SCCWRP unveils algaeMetrics tool to simplify algae-based bioassessment calculations

Posted April 29, 2016

SCCWRP has created a free online tool to help Southern California stream managers and scientists automatically generate stream bioassessment scores using raw algae data collected from wadeable streams.

The algaeMetrics calculator, unveiled in April, is designed to streamline the process by which algal indices of biotic integrity (IBIs) are calculated during stream bioassessments.

Prior to development of the calculator, stream managers were required to perform a series of lengthy calculations that required familiarity with a statistical programming language.

With the algaeMetrics calculator, the user simply uploads raw spreadsheet data to a web-based calculator, and the calculator automatically computes scores for three primary benthic algal IBIs that are used for Southern California stream bioassessments.

The three algal IBIs are described in a 2014 journal article co-authored by SCCWRP.

To request a demonstration of the calculator, contact Shelly Moore.
