Lakes Phytoplankton Primary Production

Summary

Abstract: 

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