Stream Microbial Mat Biomass (Chlorophyl-A and Ash free dry mass)

Summary

Abstract: 

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in that region. This table contains microbial biomass concentrations found at specific locations in McMurdo Dry Valley streams and mats. Microbial mat biomass has been collected as part of the McMurdo LTER since the 1993-1994 field season and measured as Ash-free dry mass (AFDM) and chlorophyll-a (Chl-a).
