Analysis results include estimates of available suitable habitat for a variety of resident fish, the best sites for placing juvenile salmonid bypass facilities, and evaluations of prototype bypass facilities. Researchers at the WFRC collect point-sampled data on terrestrial and aquatic systems and store this information in relational databases and spreadsheets. Data are collected at fixed and random locations and at locations where target organisms are found. Collected variables include vegetation type, soil type, water depth, substrate, water velocity, water temperature over time, and fish community composition. This study uses miniature depth-indicating transmitters placed in juvenile salmonids.
Mobile tracking provides information on the rate and depth of movement for individual fishes.
Results of this study are used to determine the effects of gas supersaturated conditions on the physiological performance of fishes. All fungi at each site are located and mapped by measuring the distance and azimuth from permanent benchmarks identified with coordinates from a GPS receiver. The receivers enable researchers to periodically return to benchmarks. Attributes are either logged at the time positions are collected or appended to the coordinates later. Commercial software is used to perform coordinate transformations.
