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 the glacial meltwater streams in the region. Measurements are regularly made to examine water= quality and quantity, as well as chemical and biological properties. The stream descriptions table serves as an index of the streams that have been studied. It documents the streams' basins and lengths, and provides a brief desciption of the landscape in which the streams are found.
