Bacterial Enumeration

Summary

Abstract: 

An important part of the McMurdo Long Term Ecological Research (LTER) project is monitoring spatial and temporal patterns, and processes that control bacterial production in perennial ice covered lakes. This data set quantifies bacteria concentrations at specific depths in Dry Valley lakes.
