An important part of the McMurdo Long Term Ecological Research (LTER) project is identifying patterns and movements of nutrients in perennial ice-covered lakes. This data set addresses this core area of research and quantifies macronutrient concentrations found at specific depths in McMurdo Dry Valley lakes.
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).
