Stream Chemistry - Total Nitrogen

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.

Nutrient tracer injection experiments in supraglacial streams on Canada Glacier, Antarctica, January 2019

This dataset contains a series of grab samples collected from nutrient tracer injection experiments conducted in supraglacial streams on Canada Glacier in Taylor Valley, Antarctica. The purpose of these experiments was to measure potential nutrient uptake in supraglacial stream networks. We chose three reaches and co-injected nutrient tracer(s) and a conservative tracer (NaCl). Tracers were injected at the top of each reach, allowed to mix with the stream water, and move downstream.

Surface and hyporheic porewater chemistry and sediment nitrification potentials in Von Guerard Stream, Taylor Valley, Antarctica from 2018 to 2019

Surface water and hyporheic porewater samples were collected at high frequency over two periods (01/20/2018–01/21/2018 and 01/10/2019–01/12/2019) from the lower reaches of Von Guerard Stream, Taylor Valley. Porewater samples were collected using plastic tubing inserted to depths of 15 or 30 cm and drawn out by syringe. This data set shows sampling locations, water chemistry (including concentrations for dissolved organic nitrogen species, dissolved organic carbon, silica, as well as water isotopes).
