  1. High-Resolution Elevation Mapping of the McMurdo Dry Valleys, Antarctica, and Surrounding Regions

    We present detailed surface elevation measurements for the McMurdo Dry Valleys, Antarctica derived from aerial lidar surveys flown in the austral summer of 2014–2015 as part of an effort to understand...

  2. The Impact of a Large-Scale Climate Event on Antarctic Ecosystem Processes

    Extreme climate and weather events, such as a drought, hurricanes, or ice storms, can strongly imprint ecosystem processing and may alter ecosystem structure. Ecosystems in extreme environments are particularly...

  3. Impacts of Permafrost Degradation on a Stream in Taylor Valley, Antarctica

    The McMurdo Dry Valleys (MDV) of Antarctica are an ice-free landscape that supports a complex, microbially dominated ecosystem despite a severely arid, cold environment (< 5 cm water equivalent/y, − 18 °C...

  4. 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...

  5. A Stable Isotopic Investigation of a Polar Desert Hydrologic System, McMurdo Dry Valleys, Antarctica

    The hydrologic system of the coastal McMurdo Dry Valleys, Antarctica, is defined by snow accumulation, glacier melt, stream flow, and retention in closed-basin, ice-covered lakes. During the austral summers...

  6. Water track modification of soil ecosystems in the Lake Hoare basin, Taylor Valley, Antarctica

    Water tracks are zones of high soil moisture that route shallow groundwater down-slope, through the active layer and above the ice table. A water track in Taylor Valley, McMurdo Dry Valleys, was analysed for...
