Bacterial Production (Thymidine Uptake)

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 uptake by bacteria and can be used to estimate bacterial production.
