Dissolved Inorganic Nitrogen Concentrations in Lakes

Summary

Abstract: 

The McMurdo Long Term Ecological Research (LTER) project monitors patterns of inorganic material transport in perennial ice-capped lakes. This data set addresses this core area of research and quantifies dissolved inorganic nitrogen concentrations at specific depths in McMurdo Dry Valley lakes.
