As a part of the McMurdo Dry Valleys LTER program, isotope ratios have been determined from 295 ice/snow samples in Taylor Valley, Antarctica. Hydrogen/deuterium isotope ratios are given for all samples, and for a subset, there are oxygen isotope ratios, and a deuterium-excess. Values are reported relative to VSMOW, +/- 1.0 per mil for hydrogen, and +/- 0.1 for oxygen.
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.

This data package contains chemical and other relevant characteristics for several waterfalls situated along the terminus of two glaciers in Taylor Valley, located in the McMurdo Dry Valleys region of Antarctica, during the 2017-18 and 2018-19 austral summers. Specifically, water samples were collected from terminal waterfalls along Canada and Seuss Glaciers as part of a larger study characterizing the geochemical evolution of glacier ice to meltwater.
