Huey Creek is a meltwater stream that flows into the north end of Lake Fryxell in Taylor Valley. We conducted a comparative study to determine flow balances, flow routing in Huey Creek in 2006. The hypothesis is that truncated hydrographs on Huey Creek (and other streams) are related to large subsurface storage potential that fills/empties over the daily flood pulse. The goal of the simulation and experimental data comparison described here is to use a coupled groundwater / surface flow model to test this hypothesis.
We performed a field survey to assess changes in biomass, nutrient ratios, and isotopic signatures of three different microbial mat types in two glacial meltwater streams in the McMurdo Dry Valleys, Antarctica. Samples were taken in January 2013 from pre-existing transects over Von Guerard Stream and the Relict Channel, and stretched from near the Von Guerard Glacier terminus to the stream outlets at Lake Fryxell.
