Benthic aquatic microbe samples are available from the D01 Arthur Brook (Bigelow) site at Harvard Forest, MA.
Benthic microbial sampling in wadeable streams occurs three times per year at each site, roughly spring, summer, and autumn. Benthic biofilms are collected in wadeable streams during periods of stable stream flow (e.g., when the stream is not flooding, defined as >3x median discharge for the preceding year) using a series of scrubbing procedures, depending on habitat and substratum type. Microbial samples are collected both as whole sample (plant or sediment grab) and on filters for archive and analysis.
