This data package includes measurements pertaining to the spatial distribution and multi-annual persistence of cryoconite holes on Canada and Commonwealth Glaciers in Taylor Valley, Antarctica during two consecutive austral summers (2013-14 and 2014-15). Four circular sampling zones were established on each glacier and multiple measurements of the surface shape and absolute location of all cryoconite holes within the sampling zones were recorded.
Dataset Results
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 contains daily summaries derived from 15-minute measurements of water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the daily hydrological summaries for the McMurdo Dry Valleys' Bohner Stream at the B5 streamgage, located in the Bonney Basin of Taylor Valley.

Snow patches within and adjacent to stream channels in the Fryxell Basin of Taylor Valley, Antarctica were sampled during the 2021-2022 austral summer as part of the McMurdo Dry Valleys Long Term Ecological Research program. This data package includes snow pit measurements (snow temperature, depth, density, and water equivalent) as well as chemical characteristics of snow samples that were analyzed for nutrient, cation, and anion concentrations.
