This data package provides analytic results for a laboratory assay on sediment samples collected in January 2019 from a transect (“P2”) across Von Guerard Stream (as described by Heindel et al. 2021), located in Taylor Valley, McMurdo Dry Valleys, Antarctica. We used excess sample from that study in a laboratory desorption assay to assess conductivity dependent desorption of ammonium.
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.
