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 the glacial meltwater streams in the region. Measurements are regularly made to examine water quality, quantity, and chemical properties. The stream gauge and outlet locations table serves as an index of the sampling points used to collect hydrological and stream chemistry data in the McMurdo Dry Valley network of streams.
Basic Layers from the MCM-LTER spatial data holdings have been exported and symbolized, and they are available for download here. Most of these layers date from Oct-2007 or earlier, please see the Polar GeoSpatial Center for more updated base and specialized layers.
