Chlorophyll-A Concentrations in Lakes

Summary

Abstract: 

An important part of the McMurdo Long Term Ecological Research (LTER) project is monitoring of spatial and temporal patterns, and processes that control primary production in perennial ice-covered lakes. This data set addresses this core area of research and quantifies chlorophyll-a concentrations at specific depths in McMurdo Dry Valley lakes.
