In this data package, we present chlorophyll concentrations, percent loss-on-ignition organic matter, sorbed ammonium concentrations, and percent biogenic silica for hyporheic sediments collected in January 2019 from nine transects across Von Guerard Stream, Taylor Valley, Antarctica. These samples were collected to address questions about the retention and processing of particulate organic matter in the hyporheic zone of McMurdo Dry Valley streams.
Dataset Results
This data package contains chemical and sediment characteristics of ice cores collected from the ablation zones of five glaciers in Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica, during the 2015-16, 2016-17, 2017-18, and 2018-19 austral summers. Specifically, shallow ice cores were collected from the ablation zones of Hughes, Howard, Seuss, Commonwealth, and Canada Glaciers in order to characterize the spatial and temporal evolution of ice chemistry and sediment concentration across Taylor Valley.

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.
