    I. INTRODUCTION

    The Southern California Bight (SCB; Figure I-1), an open embayment in the coast between Point Conception and Cape Colnett (south of Ensenada), Baja California, is an important and unique ecological resource. The SCB is a transitional area that is influenced by currents from cold, temperate ocean waters from the north and warm, tropical waters from the south. In addition, the SCB has a complex topography, with offshore islands, submarine canyons, ridges and basins, that provide a variety of habitats. The mixing of currents and the diverse habitats in the SCB allow for the coexistence of a broad spectrum of species, including more than 500 species of fish and 1,500 species of invertebrates. The SCB is also a major migration route, with marine bird and mammal populations ranking among the most diverse in north temperate waters.

    The coastal zone of the SCB is a substantial economic resource. Los Angeles/Long Beach Harbor is the largest commercial port in the United States, and San Diego Harbor is home to one of the largest US Naval facilities in the country. More than 100 million people visit southern California beaches and coastal areas annually, bringing an estimated $9B into the economy. Recreational activities include diving, swimming, surfing, and boating, with about 40,000 pleasure boats docked in 13 coastal marinas within the region (NRC 1990). Recreational fishing brings in more than $500M per year.

    The SCB is one of the most densely populated coastal regions in the country, which creates stress upon its marine environment. Nearly 20 million people inhabit coastal Southern California, a number which is expected to increase another 20% by 2010 (NRC 1990). Population growth generally results in conversion of open land into non-permeable surfaces. More than 75% of southern Californian bays and estuaries have already been dredged and filled for conversion into harbors and marinas (Horn and Allen 1985). This “hardening of the coast” increases the rate of runoff and can impact water quality through addition of sediment, toxic chemicals, pathogens and nutrients to the ocean. Besides the impacts of land conversion, the SCB is already home to fifteen municipal wastewater treatment facilities, eight power generating stations, 10 industrial treatment facilities, and 18 oil platforms that discharge to the open coast.

    Each year, local, state, and federal agencies spend in excess of $10M to monitor the environmental quality of natural resources in the SCB. Most of this monitoring is associated with National Pollutant Discharge Elimination System (NPDES) permits and is intended to assess compliance of waste discharge with the California Ocean Plan and the Federal Clean Water Act, which set water quality standards for effluent and receiving waters. Some of this information has played a significant role in management decisions in the SCB.

    While these monitoring programs have provided important information, they were designed to evaluate impacts near individual discharges. Today, resource managers are being encouraged to develop management strategies for the entire SCB. To accomplish this task, they need regionally-based information to assess cumulative impacts of contaminant inputs and to evaluate relative risk among different types of stresses. It is difficult to use existing data to evaluate regional issues because the monitoring was designed to be site-specific and is limited to specific geographic areas. The monitoring provides substantial data for some areas, but there is little or no data for the areas in between. Beyond the spatial limitations, data from these programs are not easily merged to examine relative risk. The parameters measured often differ among programs. Even when the same parameters are measured, the methodologies used to collect the data often differ and interlaboratory quality assurance (QA) exercises to assess data comparability are rare.

    1994 Pilot Project

    To begin addressing these concerns, twelve agencies joined in a cooperative sampling effort in 1994, called the Southern California Bight Pilot Project (SCBPP). The SCBPP involved sampling 261 sites, using common methods, along the continental shelf between Point Conception and the United States/Mexico border. Assessments were made of water quality, sediment contamination, the status of biological resources and species diversity, and the presence of marine debris. The SCBPP provided a much-needed first “snapshot” of the state of the SCB.

    Benefits derived from the SCBPP also included the development of new useful technical tools that could only be developed with regional data sets and participation by multiple organizations. For example, the project produced iron-normalization curves for the SCB, allowing distinction between natural and anthropogenic contributions of metals in sediments (Schiff and Weisberg 1998). A Benthic Response Index was developed that integrates complex benthic infaunal data into an easily interpreted form that describes the degree of perturbation at a site (Bergen et al. 1998). The project also produced a series of manuals containing standardized field, laboratory and data management approaches that increased comparability of data among participants, even after the SCBPP was completed.

    1998 Survey

    The proposed Southern California Bight 1998 Regional Monitoring Project (Bight’98) is a continuation of the successful cooperative regional-scale monitoring begun in southern California in 1994 during the SCBPP. Bight’98 builds upon the previous successes and expands on the 1994 survey by including more participants, sampling more habitats, and measuring more parameters. Fifty-four organizations, including international and volunteer organizations, have agreed to participate (Table I-1).

    The inclusion of new participants provides several benefits. Cooperative interactions among many organizations with different perspectives and interests, including a combination of regulators and dischargers, ensures that an appropriate set of regional-scale questions will be addressed by the study. The additional resources brought by new participants also expands the number of habitats and indicators that will be sampled. Sampling for Bight’98 will include all of the areas sampled in 1994, plus a new focus on nearshore habitats (bays, harbors and beaches) and offshore islands. Bight’98 will also coordinate with a Mexican program to characterize the condition of SCB coastal waters south of the US border. The new indicators that will be measured include shoreline microbiology, biomarkers and new chemical measures.

    The Bight’98 Survey is organized into three technical components: 1) Coastal ecology, 2) Shoreline microbiology, and 3) Water quality. This work plan provides a summary of the project design for the coastal ecology component. The work plan is supported by three companion documents detailing Field Methods and Logistics, Quality Assurance (QA), and Information Management. Separate work plans are also available for the shoreline microbiology and water quality two components of the program.


    II. STUDY DESIGN

    A. Study Objectives

    The overall goal of the coastal ecology component of Bight’98 is to assess the condition of the bottom environment and the health of the biological resources in the SCB. To accomplish this goal, Bight’98 will focus on four objectives:

    1. Estimate the extent and magnitude of ecological change in the SCB,

    2. Compare condition among selected geographic regions of the SCB,

    3. Assess the relationship between biological responses and contaminant exposure, and

    4. Describe historical trends at selected sites.

    The first objective, estimating the amount of area (i.e., number of acres) in the Bight in which ecological conditions differ from reference conditions, is a departure from traditional approaches to environmental monitoring, which generally focus on estimating average condition. Estimating the areal extent of ecological change offers several advantages. First, it provides a more direct assessment of status. For instance, identifying that the average concentration of dissolved oxygen in the Bight is 6.7 ppm provides less useful information for environmental managers than does identifying what percentage of the area in the Bight fails to meet water quality standards. A second advantage of estimating areal extent concerns trend detection. If conditions in the Bight change over time such that some areas improve and others worsen, the average condition might not change. By estimating the areal extent of alteration, we will be better able to describe these changes.

    The second objective of the survey is to compare condition among fifteen geographic areas of interest (Table II-1). These subpopulations of our study area were selected to represent a range of natural and potentially affected habitats, and represents a significant expansion from the number of habitats sampled in 1994. Comparison of their relative condition not only provides information about the geographic distribution of impacts, it also allows comparison of relative risk from a variety of point and non-point source discharges. Comparison of condition may be conducted by comparing the extent of area exceeding a threshold of concern or by comparison of mean condition.

    The third objective will be accomplished by simultaneously collecting numerous measures of biological response, contaminant exposure and habitat condition (Table II-2) to better identify when exposure has reached a level of concern. Measuring multiple indicators also permits us to identify the most likely type of exposure leading to biological response. Such associations provide the information necessary for risk assessment, and for developing efficient regional strategies for protecting the environment by identifying the predominant types of stress in the system.

    The fourth objective recognizes that management actions result from both assessment of present condition and from historical trends in condition. High levels of stress that are declining should result in different management actions than low levels that are increasing. This objective will be accomplished by sampling thirteen stations which have been investigated in prior monitoring programs. These stations are located in areas distant from known contamination sources, allowing assessment of integrated condition, rather than the effect of change from a particular point source. Measuring temporal change at sites distant from known point sources will also allow us to assess the effects of the recent El Nino conditions on background faunal conditions in the SCB.

    B. Sampling Design

    The coastal ecology component of Bight’98 will involve sampling of 416 sites in the SCB between July 20 and September 7, 1998. The summer period was chosen for the study because it represents a period of steady weather during which the indicators we measure are expected to remain stable.

    Maps of the sampling sites are provided in Appendix A. Sites were selected using a stratified random approach, with the strata corresponding to the subpopulations of interest in Table II-1. Stratification ensures that an appropriate number of samples are allocated to characterize each population of interest with adequate precision. We aimed to allocate thirty sites to each strata because this yields a 90% confidence interval of about ± 10% around estimates of areal extent (assuming a binomial probability distribution and p= 0.2; Figure II-1). This level of desired precision was selected because differences in response of less than 10% among subpopulations are unlikely to yield different management decisions.

    Sites were selected randomly within strata, rather than by investigator pre-selection, to ensure that they are representative and can be extrapolated to the response of the entire strata. Although sites were selected randomly, a systematic component was added to the selection process to minimize clustering of sample sites. The systematic element was accomplished by using an extension of the sampling design used in the SCBPP and in EPA’s Environmental Monitoring and Assessment Program (EMAP) (Stevens 1997). A hexagonal grid was randomly placed over a map of the sampling area, a subsample of hexagons chosen from this population, and one sample was obtained at a randomly selected site within each grid cell. The hexagonal grid structure ensures systematic separation of the sampling, while the random selection of sites within grid cells ensures an unbiased estimate of ecological condition. Further details about this site selection process are provided in Appendix B.

    One of the design attributes of Bight‘ 98 is to maximize the coincidence of indicators, allowing us to relate biological response to chemical exposure and physical habitat condition. Measuring all parameters at all sites was not possible because the resources for Bight’98 are primarily in the form of in-kind services provided by participants, and not all participants measure all parameters. The number of sites sampled for each indicator group within each strata are presented in Table II-3. To maximize overlap of indicators, sites which receive fewer indicator measurements were randomly chosen (with a systematic element) as a subset of the sites at which all indicators are measured.

    The number of sites on the maps in Appendix A exceeds the number of sites described in Table II-3 by about 10% in offshore areas and by about 20% in harbor areas. This difference between sample site selection and anticipated number of analytical results is in recognition that it may not be possible to sample all of the randomly-selected sites because of improper substrate type, depth restrictions, or dredging activities. To prevent an unacceptable loss of statistical power due to lost samples, the number of sites allocated was inflated by an expected site rejection rate, determined from historical sampling experience. Should the site rejection rate exceed this inflation factor by more than 10%, an additional set of random sites will be assigned during the survey.

    While most sites in this study were selected randomly to address population estimation objectives, eighteen sites were pre-selected to address additional objectives. Thirteen sampling sites were assigned to locations that had been sampled in historical SCCWRP reference surveys. The purpose of these samples was to assess trends in condition of the SCB at far-field reference sites, as described in Objective 4 above. Seven of those sites were located along a 60m transect that had been sampled in 1977, 1985 and 1990. Six of the sites were located along a 30m transect that was sampled in 1985 and 1990.

    An additional five sample points were assigned to river mouth areas to assess gradients in condition at varying distance from river mouths. Two of these site were assigned to the Los Angeles River, and one each to Aliso Creek, the San Gabriel River, and the Santa Ana River.

    C. Indicators

    Bight’98 will measure multiple indicators (Table II-2) at each site in order to relate contaminant exposure, biological response, and habitat condition. Collecting measures of contaminant exposure with measurements of biological response at common sites allows investigators to identify and statistically model associations between altered ecological conditions and particular environmental stresses. Habitat indicators help discriminate between changes caused by anthropogenic and natural factors.

    One design principle of Bight’98 is that these indicators will be measured using uniform sampling methods throughout the Bight. The probability-based sampling design provides a framework for integrating data into a comprehensive regional assessment, but the validity of such an assessment depends on ensuring that all the data that contribute to it are comparable. Below, we present a short description of the methods used to measure the Bight’98 indicators; more detailed descriptions of the methods can be found in the accompanying Field Methods and Logistics, and Quality Assurance Manuals for the project.

    Contaminant Exposure

    1. Sediment Chemistry: Chemical analysis of sediment samples provides an assessment of contaminant exposure for bottom dwelling animals. Sediment samples will be collected from the top 2 cm of a Van Veen grab sample. The chemical analyte list includes both inorganic and organics (Table II-4) and was developed to include contaminants of local interest as well as those measured in the nationwide NOAA Status and Trends program. Measurement reporting limits have been adopted that will allow the data to be compared to NOAA sediment quality guidelines for anticipated biological effect (Long et al. 1995).

    Organics
    Organic compounds in sediments will be extracted with solvents and cleaned to remove interfering substances. PAHs will be analyzed by GC/MS or HPLC. Organochlorine pesticides and polychlorinated biphenyls will be analyzed by GC/ECD. The accuracy of PCB measurements will be enhanced by measuring 41 individual congeners in all samples with elevated concentrations. The PCB congener list was selected to include compounds that are abundant in the environment and compounds with a high potential for toxicity.

    Inorganics
    Metals in sediments will be analyzed by ICPMS or atomic absorption spectrophotometry after strong acid digestion. Mercury will be analyzed by cold vapor technique. In addition to trace metals, the reference elements iron and aluminum will also be measured in each sample. Normalization of the trace metal data to reference element concentrations will enable anthropogenic contamination to be distinguished from natural variations in background concentrations.

    2. Interstitial Water Chemistry: Chemicals in the pore water between sand grains (interstitial water) are a more biologically available fraction of sediment contaminants than those bound to sand grains. Interstitial water will be extracted by centrifugation and subsamples analyzed for trace metals (Cd, Cu, Ni, Pb, and Zn). Sediment acid volatile sulfides concentration, which partially controls the partitioning of metals from the bound to the interstitial phase, will also be measured.

    3. Marine Debris: The amount of plastic, metal and other anthropogenic debris on the bottom is a measure of human influence on the bottom. Debris captured in trawls will be classified by type (e.g., plant material, plastic, and cans) and scored according to relative abundance.

    Biological Response

    While indicators of contaminant exposure provide an important measure of the influence of anthropogenic materials on the marine environment, it is the effect of this exposure upon biological processes that determines the significance of the contaminants. The effect of contaminant exposure will be examined through a variety of indicators:

    4. Benthic Infauna: Benthic infauna (animals that live in the sediment) are an important part of the ocean food web. Because infauna generally reside in one location for most of their lives and are chronically exposed to sediment contaminants, they are an excellent indicator of environmental quality. Samples for infaunal analysis will be taken with a 0.1 m2 modified Van Veen grab. Samples will be washed through a 1.0 mm stainless steel screen and preserved for identification to the lowest practical taxonomic unit.

    5. Demersal fish and megabenthic invertebrate assemblages: Demersal fish and megabenthic invertebrates are more mobile than the benthic infauna, but are still closely associated with the bottom and chronically exposed to sediment contaminants. Demersal fish and megabenthic invertebrates will be collected with a semiballoon otter trawl with 7.6-m headrope length and a 1.3 cm cod-end mesh. Trawls will be towed for 10 min at 0.8-1.0 m/s along depth isobaths. All fish and most invertebrates will be identified to species, counted, and weighed.

    6. Gross fish pathology: The presence and extent of external diseases (e.g. fin rot and tumors) and anomalies (e.g. skeletal deformities or abnormal coloration) will be recorded from fish collected in the trawls for assemblage analysis. Specimens with unusual or unidentified conditions will be returned to the laboratory for detailed examination.

    7. Sediment and interstitial water toxicity: Toxicity tests provide a direct measure of the effect of contamination on benthic organisms. These tests complement sediment chemistry measurements by providing a measure of the combined toxic effect of the complex mixture of contaminants present in sediment or in the water in the pores between sediment grains (interstitial water). Sediment samples will be collected from the top 2 cm of a Van Veen grab sample. A suite of four different test methods will be used in order to evaluate both acute and sublethal effects.

    Amphipod survival
    The toxicity of bulk sediments will be assessed using an amphipod survival test conducted according to USEPA methods. Amphipods will be exposed to a 2 cm layer of test sediment for 10 days and then examined to determine the percent survival. The amphipod Eohaustorius estuarius was selected for this study because of its wide tolerance to variations in habitat characteristics and to provide comparability with recent toxicity information from other monitoring programs in California.

    Microtox®
    Sublethal toxicity of interstitial water will be evaluated using the MicrotoxÒ test, in which changes in light production of a luminescent bacteria (Vibrio fisheri) are measured. This test was selected because it requires a small volume of sample and is relatively insensitive to ammonia toxicity. The test will be conducted using a 15 minute exposure to a 2 ml sample of interstitial water. Test measurements will be made at several dilutions of interstitial water and the median effect concentration (EC50) will be calculated.

    QwikLite
    Sublethal toxic effects will also be measured using the QwikLite test, which measures changes in light production from a luminescent marine phytoplankton (Gonyaulax polyedra). Several concentrations of each sample will be tested in order to calculate the median effect concentration. Sediment leachates will be prepared by mixing sediment and water in a 1:4 ratio and then allowing the mixture to settle. This test measures the toxicity of materials that are able to rapidly desorb from sediment particles.

    P450 RGS
    Sediment extracts will be analyzed for the presence of dioxin-like chemical compounds using the P450 Reporter Gene System (RGS). This test uses a human cell line which has been modified to produce a luminescent reaction when a gene responsible for the metabolism of certain organic contaminants (e.g., dioxins, coplanar PCBs, high molecular weight PAHs) is induced. The cells are exposed to a solvent extract of the test sediment for 16 hours and then measured to determine the change in luminescence. The degree of gene induction is compared to that produced by a standard and the results expressed as PAH or dioxin equivalents.

    8. Fish Tissue Chemistry: The objective of the fish tissue chemistry measurements will be to estimate health risk to marine birds, mammals and wildlife from the consumption of fish tissue. This will be addressed by measuring the whole body concentration of the chlorinated organics compounds asterisked in Table II-4. Fish in the SCB are largely segregated by depth range and no single species occurs over all of the range that will be sampled in Bight’98. To address this data comparability issue, species comprising a feeding guild (i.e. species with similar feeding strategies) will be targeted for collection and analysis. The primary target species (Category I, Table II-5) consist of species from the sanddab guild, which preliminary analyses indicate have comparable contaminant accumulation rates. An alternate guild (the Turbot guild; Category II) was identified for collection in the event that the required number of fish from Category I target species are not collected.

    9. Fish Biomarkers: Biomarkers are biochemical indicators of chemical exposure and sublethal effect that can be measured in field collected organisms. Biomarkers provide a more sensitive measure of fish health than the physiological or acute responses measured by external pathology or assemblages. Two biomarkers will be measured in the fish species collected for tissue chemistry measurements (Table II-5).

    DNA damage
    The integrity of DNA in fish blood cells will be examined by measuring DNA strand breakage using a procedure known as the Comet assay. In this test, blood cells are added to agarose-coated microscope slides and then ruptured to release the DNA. An electric field is used to separate the broken and intact portions of the DNA from individual cells. The extent of DNA breakage is indicated by the relative size of the damaged DNA portion of the sample and is measured using an epifluorescence microscope. The relative amount of damage is determined by comparing the data with reference samples having a known degree of effect. Increases in cellular DNA damage have been found to coincide with decreased health status in various types of organisms.

    Bile FACs
    Bile FACs (Fluorescent aromatic compounds) is a measure of recent PAH exposure in fish. Exposure of fish to PAH compounds is difficult to measure using conventional analytical chemistry methods because fish have the ability to rapidly metabolize these compounds. The bile FACs method measures the concentration of PAH metabolites that are excreted in bile. Fish will be collected by trawl and dissected on board to remove the gall bladder. In the laboratory, a bile sample is removed from the gall bladder and analyzed by HPLC (fluorescence detection) to determine the concentration of high and low molecular weight PAH metabolites. Metabolite concentrations will be normalized to bile protein content.

    Habitat Condition

    The distribution of biota is also affected by natural habitat factors, such as grain size and the amount of organic matter present. Habitat indicators will be measured to help distinguish the relative effects of natural and anthropogenic factors on biotic distribution.

    10. Sediment grain size: Grain size will be measured with a laser diffraction technique, a method that provides greater resolution between particle size classes with less variability than conventional pipette techniques. Two instruments will be used: 1) A Horiba LA900 which measures 74 size classes of particles between 0.05-1019 mm and 2) a Coulter LS230 that measures 116 size classes between 0.04-2000 mm.

    11. Total Organic Carbon (TOC): TOC will be measured with a Carlo Erba 1108 Elemental Analyzer equipped with an AS/23 Autosampler.

    12. Mineralogy: Mineralogy provides additional information about the shape and nature of the sediment grains. The amount of clay in the sediment will be determined by the diffraction of x-rays. The amount of heavy minerals in the sediment will be measured by counting mineral grains on glass slides.

    D. Coordinated Studies in Mexico

    While the focus of Bight’98 is on the US side of the border, a comparable, coordinated study will be conducted at 90 sites in Mexican coastal shelf waters. The Mexican component will share the first Objective of the US study, and will assess the area of 10 to 200 m depth between the Mexican border and Ensenada. Sample sites were selected using the Bight’98 sampling design.

    The Mexican component is presently limited to the collection and processing of sediment chemistry samples, though additional funding is being sought to add benthic infauna and toxicity measures, which will complete the benthic triad and allow relationship between chemical exposure and biological response measures. All sampling effort and laboratory analysis for Mexican sampling sites will be conducted by Mexican scientists, who have helped prepare, and will follow, the procedures outlined in the Bight’98 Field Methods and QA manuals. Mexican scientists have also participated in all laboratory intercalibration exercises conducted by their US counterparts.

    Coordinating these programs will allow the first unbiased comparison of relative condition between the coastal waters of the two countries. Joint participation in intercalibration exercises also provides an opportunity to establish comparability that can be exploited in cooperative programs that extend beyond the tenure of Bight’98. Additional details about the Mexican component of the program are provided in . Appendix C


    III. LOGISTICS

    Bight’98 is a complex project with 11 organizations collecting samples (Table III-1) and 12 organizations processing them in the laboratory (Table III-2). For most samples, collection and processing will be conducted by different organizations. Such complexity requires an effective plan for transferring and tracking samples among organizations. The details of that plan are provided in Bight’98 Field Methods and Logistics Manual; a short summary of that plan is provided here.

    SCCWRP will be responsible for tracking all samples collected during Bight’98. Chain of custody forms will be used to track each sample from the time it is collected to its final destination in the laboratory. At the end of each sampling day, the field crew will fill out a form for each set of samples to be transferred. This form will be signed by the crew member transferring the samples and the laboratory staff member receiving them. A copy of the form will be kept and the original form with signatures will accompany the samples. Copies of all chain of custody form will to be faxed or delivered to SCCWRP.

    Samples being processed by the organization collecting the samples will be sent directly to the organization’s laboratory. All other samples will be sent to SCCWRP for re-distribution to the processing lab. For items that must be processed quickly (Toxicity, AVS), samples will be redistributed to the processing labs at the end of every week. All other items will be accumulated and redistributed at the mutual convenience of SCCWRP and the processing labs.


    IV. INFORMATION MANAGEMENT

    A. Overview of Approach

    Bight’98 is based on the principle of partnership; all participating organizations will have equal and complete access to the data collected during the project. Historically, each organization has collected and managed its own data. Consequently, there are many different information management systems in Southern California, which impedes sharing of data among project participants. Bight’98 will address this challenge by developing and implementing an integrated, uniform, and well-documented information management system (IMS). The foundation for this system was developed during the SCBPP, when procedures were developed to facilitate data transfer and sharing between participants, and will be enhanced for Bight’98 to include a more rigorous quality assurance program. The highlights of the system are presented here; additional details are presented in an accompanying information management manual.

    The core of the IMS will be a set of standardized data transfer protocols (SDTP) for sharing information among project participants. These protocols will be an expansion of the formats developed during the SCBPP and will detail the information to be submitted with each sample collection or processing element, the units and allowable values for each parameter, and the order in which that information will be submitted. Use of SDTP allows each participating organization to retain their existing data management system, yet output the data in a manner that allows sharing among organizations.

    The SDTP calls for sharing of data at the level of individual replicate, rather than in a summarized format. The protocols will also carry summary quality assurance (QA) information, though routine laboratory QA procedure data (e.g. blanks, spikes) will be retained at the individual laboratory. Our objective in selecting which QA data to carry within the IMS will be to provide the user enough information to evaluate the data.

    A second attribute of the IMS will be centralized data storage. Bight’98 includes many collaborators, with eleven boats responsible for sampling and a dozen labs responsible for laboratory processing, which precludes a distributed system. The centralized location will be at SCCWRP, where it will be stored on personal computers in Microsoft Access.

    B. Data Flow and Quality Assurance

    Each field crew or laboratory generating data will initially enter it into their own data management system and subject it to their internal QA/QC procedures. Recommended QA will include double punching of data and range checks. Data will next be reformatted into the SDTP and submitted to the Information Management Officer (IMO) at SCCWRP in comma-delimited, ASCII format.

    Upon receipt, the IMO will check the data for errors, such as inclusion of all required fields, range checks, and proper naming conventions for text fields. Most of the error checking will be automated, conducted by a computer program developed specifically for Bight’98. The program will identify potential errors in the data by comparing the submitted values to expected ranges and formats specified in the information management plan. Small errors will be corrected by the IMO with the consent of the submitting lab; data sets with larger errors will be returned to the providing lab for correction, along with a list of corrections that the organization needs to make.

    Once the IMO has certified that the data is consistent with the SDTP requirements, the data will be distributed to the Technical Committee Chair (TCC) responsible for that class of data. The TCC, with assistance of their Technical Committee, will review the data with respect to scientific content. This review will involve plotting of data and examining interrelationships among individual parameter responses and will address more extensive data quality issues than can be accomplished by range checking alone. The TCC will communicate any identified data problems to the IMO.

    All corrections to the data will be made by the IMO; access to the database for other users will be in read-only form. Prior to making any changes, the IMO will document the changes and receive (written or electronic) concurrence from the organization that originated the data. The IMO will only make changes in the centralized data base; originating organizations will be responsible for making corresponding changes in their own internal data storage systems. All changes to the data will be documented in a computerized file available to all data users.

    C. Data Availability

    All data from Bight’98 will be made publicly available, though the schedule of availability will vary by user class. The different schedules recognize the differing levels of quality assurance and data documentation that will have been completed at various stages in the project. Four classes of user have been identified:

    1. Information Management Officer: All organizations will submit data to the IMO within one month of completing their assigned sample collection or laboratory processing task. The amount of time before data is expected to reach this stage varies by indicator and is summarized in Table IV-1.

    2. Technical Committee Members: The Technical Committee Chairs will be provided data of the type for which they are responsible immediately following certification by the IMO that the data follows the SDTP formats. The TCCs will work with their Committee members to conduct scientific content review.

    3. Steering Committee Members: All project participants will have access to data once the TCC has conducted initial scientific review for data quality. TCCs will be asked to complete this review within three months.

    4. General Public: Data will be released to the general public once the TCC has conducted initial data analysis and the Steering Committee has accepted an oral report from the TCC that summarizes the major project results for that data type. TCCs will be asked to make this presentation, and provide summary results tables from the presentation, within six months of releasing data to the Steering Committee.

    Each release of data will include comprehensive documentation. This documentation will include a lookup tables used to populate specific fields in specific tables, access control, and database table structures (including table relationships). It will also include quality assurance classifications of the data (flags, as appropriate) and documentation of the methodologies by which the data were collected (metadata).


    V. QUALITY ASSURANCE AND QUALITY CONTROL

    Quality assurance/quality control (QA/QC) is an important part of any environmental monitoring project. A carefully planned QA/QC program ensures that the data collected are scientifically valid, comparable, and adequate to meet the goals of the study. QA/QC is particularly important for large monitoring projects like Bight’98 that involve many participants.

    The QA/QC program consists of two distinct but related activities: quality assurance and quality control. Quality assurance includes design, planning, and management activities conducted prior to the study to ensure that the appropriate kinds and quantities of data are collected. Quality control activities are implemented during the project to evaluate the effectiveness of the QA activities in controlling measurement bias and error. QA activities are emphasized in Bight’98 due to the distributed implementation of the project. The QA and QC activities are outlined below; a complete description of the QA/QC elements for each field or laboratory component can be found in the Bight’98 Quality Assurance Plan.

    A. Quality Assurance Elements

    The QA activities are intended to ensure that comparable data are collected and that the number of lost or damaged samples are minimized. Four types of QA activities will be conducted prior to the collection or analysis of samples.

  • Standardization of sample collection, processing, and analysis methods
    The use of standardized field sampling methods is important for ensuring data comparability because the type of gear and how it is used can affect the final data. Methods for the collection and handling of samples in the field will be standardized and documented in the Bight’98 Field Methods and Logistics Manual. In addition, some analytical methods (e.g., sediment toxicity testing) will be standardized among laboratories. Standardization of analytical methods is not possible for all parameters due to differences in instrumentation among laboratories. For these parameters, comparability of the analytical measurements will be documented by a performance-based program that includes the analysis of standard reference materials.

  • Training workshops for field and laboratory personnel
    Standardized methods cannot specify every detail of a procedure or anticipate unusual events. Training of field and laboratory personnel is needed to ensure that the methods are being followed correctly and that the participants have an adequate level of expertise to conduct the study. Bight’98 training activities will include meetings of field and laboratory technical committees to discuss methods, joint workshops with the Southern California Association of Marine Invertebrate Taxonomists (SCAMIT), exchange of voucher specimens, and field review/training exercises for sampling and fish dissections methods.

  • Establishment of Measurement Quality Objectives
    Measurement Quality Objectives (MQOs) specify acceptable levels of precision, accuracy, and completeness for each measurement (Table V-1). Establishment of standard, quantitative MQOs for precision and accuracy will ensure that individual data sets produced by the field crews and laboratories will be comparable and free of any crew- or laboratory-specific bias. An MQO of 90% for completeness has been established for Bight’98. Completeness is a measure of the proportion of the expected, valid data that is actually collected during a measurement process. Large monitoring programs typically lose some samples due to logistical difficulties or failure to achieve laboratory quality control criteria. The sampling design for Bight’98 is sufficiently redundant to absorb the loss of up to 10% of the samples without compromising the goals of the program
  • Interlaboratory comparison exercises
    The comparability of laboratory data produced during Bight’98 will be assessed prior to the survey, since multiple laboratories will be measuring most indicators (Table II-3). Presurvey interlaboratory comparison exercises are especially valuable since they provide an opportunity to identify problems and correct them before data quality is compromised. Participation in presurvey interlaboratory comparison exercises is a requirement of laboratories processing Bight’98 samples. These exercises will include the analysis of split samples for sediment chemistry and the identification of fish and invertebrate voucher specimens.
  • B. Quality Control Elements

    A QC program will be conducted to ensure that measurement error and bias are identified, quantified, and accounted for or eliminated if practical. The QC program is performance based, which means that data quality is assessed on the basis of each laboratory’s ability to produce measurements that meet specific MQOs. The Bight’98 QC program includes both internal and external procedures.

    Internal QC procedures include activities performed on the Bight’98 samples. For chemistry, toxicity, and biomarker measurements, internal procedures include routine checks of instrument calibrations and analysis of spiked and duplicate samples. These internal QC checks are conducted on a frequent basis during the survey, so that problems with personnel or instrumentation can be identified and corrected at an early stage. Taxonomic performance for benthic infauna will be evaluated by the reanalysis of a subset of the samples. Taxonomic performance for identification of megabenthic invertebrates and demersal fish will involve expert re-identification of voucher specimens.

    External QC procedures include the analysis of reference or split test samples among laboratories to provide an ongoing evaluation of interlaboratory data comparability. In addition, field performance audits will be conducted by individuals designated by the technical committees. The performance audits will include visits to each vessel during the survey to verify that the correct sampling and taxonomic procedures are used.


    VI. PROJECT MANAGEMENT

    A. Management Structure

    Almost a thousand people from 50 organizations are involved in the planning and implementation of Bight’98. Success of the program depends largely on an effective management structure to communicate project objectives and coordinate the effort among participants to produce data that are reliable and comparable. This is being accomplished with a three-tier management structure; the three tiers have distinct roles and provide the opportunity for participation by different levels of personnel from within each participating organization (Figure VI-1).

    At the center of the Bight’98 management structure is the Steering Committee, which is composed of scientifically-trained, mid-level managers from each of the participating agencies (Table VI-1). The Steering Committee is responsible for overall planning of the project, including establishing project objectives, developing the sampling design and selecting the indicators to be measured. Steering Committee members are responsible for defining the resources their organization bring to the project and for ensuring that the objectives set forth for the project are achievable within the cumulative set of resources available. The Steering Committee also serves as a point of technical review for all documents that are produced by the project. Participation on the Steering Committee ensures each participating organization the opportunity to direct the program through a consensus building process.

    The Steering Committee is supported by eight technical subcommittees, which are responsible for recommending technical approaches to accomplish the objectives set forth by the Steering Committee. There are two different types of technical committees that support the Steering Committee. The first group are discipline-specific committees, including Sediment Chemistry (which has formed metals, PAH and PCB subcommittees), Toxicology, Fish, Benthic Infauna, Water Quality and Microbiology. The second group are cross-cutting committees, including Field Methods/Logistics and Information Management. Technical committees are responsible for preparing methods and quality assurance manuals for the project. They are responsible for implementing the quality assurance procedures (e.g. intercalibration exercises) prior to the study and the quality control assessments during the study. Additionally, the discipline-specific committees are responsible for preparing the reports that summarize project data from within their discipline. Technical Committee representatives are generally scientists with extensive knowledge within the discipline and are appointed by Steering Committee members. Technical Committees ensure that the abilities and expertise available from the diverse participants in Bight’98 are exercised to the fullest advantage throughout the project. Appendix D lists current members of each Technical Committee.

    Technical Committees make recommendations and present draft documents to the Steering Committee. The Steering Committee is responsible for assessing whether these recommendations and documents are consistent with the project objectives and for assessing whether the costs of the recommendations are consistent with the resources available for conducting the project. The Steering Committee is also responsible for resolving conflicts that arise within or among Technical Committees.

    The third tier of project management is the SCCWRP Commission, which is the primary audience for the products of this project. SCCWRP is a joint powers agency, that is coordinating Bight’98. The SCCWRP Commission is a nine-member board that is composed of the highest level of management from each of the largest municipal dischargers to Southern California Bight and from each of the agencies responsible for regulating discharge to the Bight. Reporting to the SCCWRP Commission, which meets on a quarterly basis, ensures that the questions addressed by Bight’98 remain relevant to current management issues. Reporting to the Commission also maximizes the likelihood that the project results will be incorporated into the southern California environmental management decision-making arena.

    B. Project Reporting

    Bight’98 will produce four types of technical reports. The first will be Technical Committee reports, with each Technical Committee assigned a group of indicators to be included in their report (Table VI-2). These reports will focus on addressing the core questions of the project. Generally, the Technical Committees will be asked to present their reports orally to the Steering Committee about six months after the data have past Technical Committee QA review. Written reports will generally follow about six months after the oral report.

    While Technical Committees are being asked to produce draft written reports within one year after data availability, this is an aggressive schedule that may require some flexibility. Bight’98 involves a large number of participants and includes measurement of new indicators in unfamiliar habitats. More importantly, one of the focal points of the Bight’98 reporting process will be consensus among project participants, and consensus about data interpretation is not always reached quickly. All project participants are provided the opportunity to place members on any of the Technical Committees that are preparing reports; in addition, all project reports will be reviewed by the Steering Committee, where additional opportunity for discussion will take place. One of the strengths of the 1994 SCBPP was the healthy dialog that took place among the varied project participants, an aspect we’d like to mimic in Bight’98.

    The second type of report will be indicator development reports. Indicator development reports will assess the quality of information produced by selected indicators, or will use information from the project to enhance information produced by a set of measurements. Examples of such reports include the iron-normalization curves and Benthic Response Index developed during the SCBPP. Indicator development reports will lag the basic Technical Committee reports because they typically require data from multiple indicator groups, which may be available on different time schedules. Indicator development reports may be produced as appendices to Technical Committee reports, if they are available in an appropriate time frame.

    The third type of report will be cross-cutting reports that relate biological response to contaminant exposure. The target date for these reports will be about three years after sample collection. These reports take longer to produce because they require expertise and interaction among multiple Technical Committees. In addition, these reports require multiple types of data and are time-limited by the last data to became available from the laboratory.

    The last type of report will be an Executive Summary Report (ESR). The target ESR will be a 25 page document that summarizes all aspects of the projects findings and is intended for easy reading by upper level managers and the general public. The first three types of reports will generally be long, technically complex, and contain many details of interest only to the most dedicated scientists. The ESR will be prepared in recognition that our primary audience for this study is the SCCWRP Commission and other SCB environmental managers. The Steering Committee will have the responsibility for selecting from and summarizing the massive amount of information that will be produced in this project into a format that can be easily assimilated by the primary target audience. The ESR will follow production of the other document types and should be available about three years after sampling is completed.

    APPENDIX B. SAMPLE SITE SELECTION PROCESS

    Sample sites for Bight’98 were selected using an extension of the sampling design used in the SCBPP and by EPA’s Environmental Monitoring and Assessment Program (EMAP) (Stevens 1997). The design calls for a double randomization superimposed upon a spatially systematic element. The systematic element is created by linearizing two dimensional space using hexagons that spatially order the sample frame and then stratifying that linear space. The double randomization follows from random selection of individual hexagons within the stratified units, and then random selection of specific sampling coordinates within the selected hexagon.

    The address scheme used to spatially order the hexagonal grid was developed by picking one of the hexagons near the center of the study area and linking it with the six adjacent hexagons to form a cluster of seven hexagons, or a hexal. The seven hexagons were numbered starting in the center with 0, and proceeding up and clockwise (Figure B-1). Construction of the addressing system continued by surrounding the hexal just formed with six other hexals of the same shape (Figure B-2). This time, however, the seven components of the hexal are themselves hexals rather than hexagons. This pattern of a central figure surrounded by six identical figures can be continued indefinitely.

    The resulting figures have interlocking shapes, so that they fit together leaving no spaces. At each stage, the figures are numbered in the same manner: the central figure is numbered 0, and the other six are numbered in sequence by moving up and clockwise. This numbering scheme produced a hierarchical numbering system and a spatial address for each hexagon. The highest order digit corresponded to the highest order hexal, the next digit specified a hexal within the high-order hexal, and so on down to the low order digit which specified a hexagon.

    The subsample was chosen by placing the hexagons along a number line in the order given by the hierarchical numbering system. Each hexagon was assigned a unit length on the line, and then the hexagons were subsampled using a systematic sample with a random start. The selection interval was the ratio of the required sample size to the number of hexagons on the line. This procedure selected a random point r between 0 and 1, the length of the selection interval. That point falls in the unit length associated with some hexagon, and the random point in that hexagon becomes a sample point. Subsequent points and hexagons were selected at equal intervals (i) along the line at r+i, r+2i, r+3i and so on.

    Implementing this design involved application of the EMAP hexagonal grid system at 5 different levels of enhancement, corresponding to the various subpopulations. The enhancements were 4x9x9x9 for Bays and Harbors, 3x4x4 for Deep subpopulations, 3x3x3x4 for Islands, 3x7x7 for Large POTWs, and 3x3x4 for Shallow and Mid-depth subpopulations. The enhancements were chosen to achieve the minimum number of sites per subpopulation.

    To maximize overlap of indicators, the design was first implemented for the indicator group with the highest sample density within each subpopulation. Random subsamples of these were then selected to produce nested designs for the indicator groups that were measured at a smaller number of sites within the subpopulation.

    Within the river mouths and small POTW strata, there was an additional design criterion to assign nearly equal numbers of sample sites to each of the individual discharge areas. For river mouths, this was accomplished by laying out a systematic random sample, resulting in approximately 3 sites per river mouth. A simple random sample of 4 sites were placed in each Small POTW.
