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 package addresses this core area of research by quantifying chlorophyll-a concentrations within specific depths along the water column of several lakes located across the McMurdo Dry Valleys region of Antarctica.
