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 that region. This package contain data pertaining to continuous monitored water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the hydrology data set for the McMurdo Dry Valleys' Lawson Creek at the B3 streamgage, located in the Bonney Basin of Taylor Valley. Measurements commenced during the 1994-95 season. The data associated with this record can be used to extrapolate the discontinued hydrological data nearby at the Santa Fe Stream. This dataset extends through the first half of the 2019-20 field season.
