McMurdo Dry Valleys LTER: 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 d...

| Summary: | 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). A laboratory nitrification potential assay was performed on sediments from Von Guerard stream to assess the functional microbial potential of the hyporheic microbial community to perform nitrification. |
