Chemical characteristics of snow in the ablation zone of Canada Glacier in the McMurdo Dry Valleys, Antarctica during the 2016-2017 austral summer

Summary

Abstract: 

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. Samples were collected in triplicate near mass balance stakes on the same date ice cores were collected as part of a larger study characterizing the spatial and temporal geochemical evolution of glacial meltwater. A subset of snow samples collected from Canada Glacier have been analyzed and are included here. This package may be amended in the future if analysis of the remaining samples from both Canada and Commonwealth Glaciers occurs.
