McMurdo Dry Valleys LTER: Dissolved oxygen measurements in supraglacial streams on Canada Glacier, Antarctica, January 2019

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. Over the course of their deployment, two of the three locations had issues with freezing around the sensor and produced large artifacts (swings) in the data.Â
