Phytoplankton primary production measurements from discrete water column samples collected from lakes in the McMurdo Dry Valleys, Antarctica (1993-2022, ongoing)
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 dataset addresses this core area of research and quantifies carbon production at specific depths in McMurdo Dry Valley lakes.
