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.

Long-term ecological field surveys from the McMurdo Dry Valleys Long Term Ecological Research program (MCM LTER) have documented the abundance and diversity of microbial mat types across ephemeral glacial meltwater streams in the McMurdo Dry Valleys region of Antarctica. However, field surveys are limited and are incapable of being performed across the entirety of streams within a field season.

An intensive field campaign was conducted during the 2018-2019 austral summer to assess spectral and biological characteristics of multiple microbial mat types, as well as mosses, across nine ephemeral glacial meltwater streams in the Fryxell Basin of Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica.
