Stream Chemistry - Total Nitrogen

Summary

Abstract: 

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of terrestrial water samples have been collected and analyzed for dissolved total nitrogen levels. This dataset shows concentrations of total nitrogen (in filtered samples) found in various streams of the McMurdo Dry Valleys.
