This report presents detailed methods and basic results of a benthic survey designed to detmine long-term trends in the macrobenthos of southern Lake Michigan. Forty stations were sampled in late May/early June, July, and September of 1980 and 1981. Each of the forty stations represented a location that was sampled in one of several earlier surveys. At each station, three replicate samples were generally taken with both a Peterson and a Ponar grab sampler. The benthic data for each sampling date and station are presented in a table giving (1) number of each taxa found in each replicate sample, (2) mean abundance determined separately for each type of sampler, (3) ash-free dry weight found in each replicate sample for the major taxa, and (4) mean ash-free dry weight for the major taxa. |
