  1. A Dynamic Physical Model for Soil Temperature and Water in Taylor Valley, Antarctica

    We developed a simulation model for terrestrial sites including sensible heat exchange between the atmosphere and ground surface, inter- and intra-layer heat conduction by rock and soil, and shortwave and...

  2. Snow-Patch Influence on Soil Biogeochemical Processes and Invertebrate Distribution in the McMurdo Dry Valleys, Antarctica

    The McMurdo Dry Valleys is the largest of the ice-free areas in Antarctica. Precipitation events in excess of 1 cm of snow accumulation are rare. During the winter, snow is transported by strong katabatic winds...

  3. Decadal Ecosystem Response to an Anomalous Melt Season in a Polar Desert in Antarctica

    Amplified climate change in polar regions is significantly altering regional ecosystems, yet there are few long-term records documenting these responses. The McMurdo Dry Valleys (MDV) cold desert ecosystem is...

  4. Biogeochemical Stoichiometry of Antarctic Dry Valley Ecosystems

    Among aquatic and terrestrial landscapes of the McMurdo Dry Valleys, Antarctica, ecosystem stoichiometry ranges from values near the Redfield ratios for C:N:P to nutrient concentrations in proportions far above...

  5. High-Resolution Ground-Penetrating Radar Profiles of Perennial Lake Ice in the McMurdo Dry Valleys, Antarctica: Horizon...

    Ground-penetrating radar (GPR) is not commonly used to study lake ice, and in general, the ground-based use of radar frequencies greater than 500 MHz in cryosphere geophysics is rare, due to a general interest...
