Geochemical flux on Commonwealth glacier

As part of a geochemical study of the Commonwealth Glacier in Taylor Valley, Antarctica, two 3-meter snow pits were dug in the accumulation zone and analyzed for major ions by ion chromatography. This dataset shows the mean annual atmospheric flux of chloride, sulfate, nitrate, and calcium to the Commonwealth Glacier. Determination of the atmospheric flux of these ions to the glacier surface aids in assessing the chemical composition of precipitation to the McMurdo Dry Valleys and the role of glaciers in the geochemical cycles of the region.

Cation, Anion Concentrations Along Lake Sediment/Water Interface

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 water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids from fresh to hypersaline lake waters. This dataset shows concentrations of lithium, sodium, potassium, magnesium, calcium, iron, chlorine, bromine, and SO4 found along the sediment/water interface of Taylor Valley lakes.

Lake Hoare Tracer Test Stream Chemistry

As part of the McMurdo Dry Valleys, Long Term Ecological Research (MCM-LTER) project in Antarctica, a LiCl tracer was injected into Andersen Creek in the Lake Hoare basin on 17 December 2012. The purpose of this study was to determine the fate of stream water below lake ice. Injection began at 20:30 hours and continued for two hours. Water samples were collected at half-hour intervals from 5 stream sites and 15 ice boreholes over a 4 hour period beginning at the start of injection. Samples were analyzed for major cations and major anions using an ion chromotograph at McMurdo Station.

Tracer Experiment Stream Chemistry

As part of the new 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 major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids (TDS) from relatively pristine glacier ice to hypersaline lake waters.

Major ion and nutrient concentrations of water-soluble salts leached from aeolian material, McMurdo Dry Valleys, Antarctica (2013-2016)

To evaluate the role of Antarctic aeolian transport in surface chemistry homogenization, fifty-three samples of aeolian material from the McMurdo Dry Valleys region of Antarctica were collected and analyzed for water-soluble major ions and nutrients at a 1:5 sediment:water ratio. Samples were collected seasonally from Alatna Valley, Victoria Valley, Miers Valley, and Taylor Valley (Taylor Glacier, East Lake Bonney, F6 (Lake Fryxell), and Explorer’s Cove) at five heights (~5, 10, 20, 50, 100 cm) above the surface between 2013 and 2015.

Snowpit chemistry from Canada, Commonwealth, and Rhone Glaciers, McMurdo Dry Valleys, Antarctica during the 2000-2001 austral summer

To examine temporal and spatial variability in snow chemistry during the 2000-2001 austral summer, snow samples were collected from the accumulation zones of Canada, Commonwealth, and Rhone Glaciers, located in Taylor Valley in the McMurdo Dry Valleys region of Antarctica. Snowpits were excavated to a depth of 2 meters at each location and samples were collected using a depth interval of 3 cm utilizing clean sampling techniques. Snow density was measured in the field at the time of sample collection. Samples were analyzed for major ions in the Crary Lab at McMurdo Station.
