This dataset contains a series of grab samples collected from nutrient tracer injection experiments conducted in supraglacial streams on Canada Glacier in Taylor Valley, Antarctica. The purpose of these experiments was to measure potential nutrient uptake in supraglacial stream networks. We chose three reaches and co-injected nutrient tracer(s) and a conservative tracer (NaCl). Tracers were injected at the top of each reach, allowed to mix with the stream water, and move downstream.
We installed dissolved oxygen sensors in three locations on a supraglacial stream network on Canada Glacier in Taylor Valley, Antarctica in conjunction with a series of nutrient tracer injection experiments. This data collection was intended to provide context for respiration and primary productivity via dissolved oxygen dynamics during our nutrient tracer injections. Sensors were deployed a day before the start of the tracer series and collected on the last day of experiments.
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.
