As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor glacial mass balance and meltwater flow. This data package includes stake height and snow depth measurements to the surface of six glaciers (Canada, Commonwealth, Hughes, Suess, Howard, and Taylor) in Taylor Valley and one glacier (Adams) in Miers Valley, all of which are located in the McMurdo Dry Valleys of Antarctica. Most measurements began during the 93-94 field season.
Dataset Results
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.

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor glacial mass balance and meltwater flow. This data package includes snow density measurements determined at each stake with snow present on glaciers in Taylor Valley (Canada, Commonwealth, Howard, and Taylor) and Miers Valley (Adams), all of which are located in the McMurdo Dry Valleys of Antarctica. Included here for each stake are the snow thickness and density for each layer and the average density for each pit.

Increases in soil moisture from snow packs may influence distribution and abundances of soil invertebrates. In this study, two snow fences were erected in Lake Fryxell and Lake Bonney basins to trap snow and examine the effects of increased snow pack on soil physical, chemical and biological properties.

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.
