Description:
We conducted a probability-based sampling of Lake Superior in 2006 and compared the zooplankton biomass estimate with laser optical plankton counter (LOPC) predictions. The net survey consisted of 52 sites stratified across three depth zones (0-30, 30-150, >150 m). The LOPC tow surveys were extensive and spatially covered much of Lake Superior (>1300 km). The LOPC data was field calibrated to Lake Superior zooplankton net samples and collected across the years of 2004 to 2006. The volume-weighted lake wide zooplankton biomass determined by traditional net tows to 100 m was found to be 20405
