This data package contains chemical characteristics of water samples collected along four supraglacial streams on Canada Glacier, located in Taylor Valley, McMurdo Dry Valleys, Antarctica. Samples were collected during the 2015-16 and 2016-17 austral summers in order to characterize the spatial and temporal evolution of glacial meltwater as it travels over and off Canada Glacier. Samples from the 2015-16 austral summer have been fully analyzed and those data are included here.
Dataset Results
Elemental stoichiometry is a useful theoretical framework for understanding the sources and controls on nutrient availability that can structure the composition, diversity, and life history of biotic communities. One such relationship, as postulated by the growth rate hypothesis (GRH), is that organismal development rate is positively linked to cellular phosphorus (P).

As part of the McMurdo Dry Valleys Long Term Ecological Research program, continuous stage (lake level) and ice surface ablation were collected at Lake Hoare, located in Taylor Valley, Antarctica. This package contains data measured at 1-minute intervals from Nov 2012 to Apr 2013, Nov 2013 to Feb 2014, and Nov 2014 to Oct 2016.

This data package contains chemical characteristics of snow in the ablation zone of Canada Glacier, located in Taylor Valley, McMurdo Dry Valleys, Antarctica during the 2016-17 austral summer. Specifically, snow samples were collected from the ablation zones of Canada and Commonwealth Glaciers to characterize the chemistry of recent snowfall in the ablation zones of these glaciers.
