Thymidine uptake rates for estimating bacterial production in lakes, McMurdo Dry Valleys, Antarctica (1993-2019, 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 bacterial production in perennial ice-covered lakes. This data set quantifies thymidine (TdR) uptake by bacteria, which can be used to estimate bacterial production.

Date Range: 

October 27, 1993 to December 17, 2019
