Abstract:
All wastewater monitoring programs assess the environmental situation in the discharge area by comparing it to the situation where there is no discharge. Thus the selection of the reference or control stations is of critical importance in evaluating effects: Control stations must be as similar as possible to the area being studied except that they are not exposed to outfall materials. The Project has encountered the problem of selecting proper control sites in designing its surveys of southern California discharge areas. We considered using sites off the Channel Islands but rejected them because they are not oceanographically or biologically comparable to mainland sites. We also looked at data from the control sites used in the past by various dischargers and found that some of these were in areas influenced' by the outfalls being investigated and consequently gave invalid reference information. In some monitoring surveys, a single reference station and a single set of measurements have been used as the basis for determining the natural or background conditions for an outfall site. Yet careful analysis of many samples reveals that chemical and biological conditions vary with water depth and type of bottom material and can differ by as much as a factor of 10, even in areas not influenced by man. Plainly, no single control station or set of measurements is valid for reference purposes. Numerous benthic monitoring surveys, designed to assess the effects of existing or future discharges, have been taken on the southern California mainland shelf since 1956. While such surveys have provided much new information on the abundance and diversity of thousands of species of bottom organisms and fishes, and on the levels of pollutants in sediments around outfalls, few have provided a data base that would permit the identification of control sites, or areas where background conditions exist. An outstanding exception is the mainland shelf survey produced by the California State Water Resources Control Board and conducted some 20 years ago by the Allan Hancock Foundation, University of Southern California (California State Water Resources Control Board 1967; Jones 1969). That survey provided useful information on conditions at that time; however, we do not know if the results are representative today. Moreover, the previous survey did not provide data on sediment pollutant concentrations or trawl-caught fish and invertebrate populations--two types of information that are needed at present, particularly for rural areas of this coast. Accordingly, in 1977, the Coastal Water Research Project sponsored a new survey of the mainland shelf from Point Conception to the United States/Mexico border. The goal of the survey was to identify possible control areas for contrasting with existing municipal wastewater discharge sites and to define the apparent normal variations in the chemistry and biology of the fine sediment areas covering much of the mainland shelf.
Purpose:
We now believe we have identified 29 locations, the combined information from which can be used as control data for one depth--60 meters. We chose to limit this survey to the single depth because this is the depth of discharge of the largest municipal wastewater treatment plants along the coast -and because discharged materials tend to drift along depth contours. Details on the methods and results of the survey are given in the following sections.
Supplemental_Information:
Grabs, Trawls, and Water Quality casts were conducted at each of the stations to yield Benthic infauna, Sediment Chemistry, Trawl Fish, Macro Invertebrate, water column characterization at one meter increments from surface to bottom, and sediment grain size data. These data types can be aggregated using the StationID variable in each table. Between 28 April and 9 August 1977, 70 benthic grab samples and 53 trawl samples were taken at 71 stations between Point Conception and the U.S./Mexico border. The stations were located at intervals of approximately 10 km along the 360 km of coastline at depths of approximately 60 meters. In certain areas near the major municipal wastewater outfalls, stations were more closely spaced to delineate the expected outfall effects. Station locations are given in tblStations. Position on station was determined through the combined use of dead reckoning, sightings off headlands, radar fixes, and depth measurements from a recording fathometer. We have estimated that the inaccuracy of positioning do not exceed 100 meters. The vessels used during the survey are as follows: 1. M/V Marine Surveyor, Los Angeles City, John Keller, Skipper. 2. M/V Fury II, Orange County Department of Education, John Haas, Skipper~ 3. M/V Monitor II, San Diego City, Susan Hamilton, director of collecting efforts. 4. M/V Enchanter IV, Fred Munson, Owner/Operator. 5. R/V Sea-S-Dee, Los Angeles County Sanitation Districts, Rusty Shields, Skipper. 6. R/V Van Tuna, Occidental College, Elden McAllicher, Operator.

Methodology_Description:
One otter trawl was taken at each of 53 of the 60-meter stations using single-warped, 7.6-meter (headrope length) otter trawls manufactured by Willis or Marinovich. The Willis net, which was used at the majority of the stations, is described in detail in Table 4. At all but the Palos Verdes and Orange County stations, the trawl was deployed according to deck procedures described by Mearns and Allen (1978) and towed astern at a scope ratio (towing cable length vs. water depth) of 3 to 1 for 10 minutes on-bottom time. (The on-bottom time is the time between the full deployment of the cable and the initiation of net retrieval; in actual practice, the trawl actively captures fish on bottom for a somewhat longer time.) All tows were along the 60-meter isobath. Stations off Palos Verdes were sampled for 10 minutes on-bottom time using Willis gear; the speed of the vessels was 2.5 knots, and the scope ratio was 3 to 1. Off Orange County, a Marinovich net was towed for 10 minutes on-bottom time at each station; the vessel speed was 2.5 knots, and the scope ratio was 3.3 to 1. Previous studies (Mearns and Stubbs 1974) indicated that 7.8-meter trawls operate with door-to-door spreads ranging from 2 to 7.5 meters,' Field measurements indicate that the Willis gear opened 5 to 6.2 meters, and the Marinovich gear opened 4.9 meters. Given these net spreads and the towing speed and on-bottom time used in this survey, each tow probably covered an area of about 3,700 sq meters. All fish taken in each tow were identified, counted, weighed, and externally examined aboard ship. All fish were measured for board length; members of abundant taxa (more than 10 individuals) were measured to the nearest centimeter, and individuals representing less abundant taxa were measured to the nearest millimeter. Organisms showing signs of disease, parasitism, or abnormalities were preserved in 10 percent phosphate-buffered formalin and returned to the laboratory for further examination. Finally, numbers of newly recruited fishes were determined by inspecting the size class information and noting the asymmetric patterns that indicate the presence of individuals new to the population.
