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 used sediment incubations to quantify and compare nutrient uptake rates from biota living in sediment across glaciers in Taylor Valley, Antarctica. Hughes Glacier is located towards the polar plateau on the western edge of the valley and flows from the southern Kukri Hills north into the valley. Canada and Commonwealth glaciers flow south into the valley from the Asgard range. Commonwealth glacier is located closest to the ocean on the east end of the valley. Canada glacier is located mid-valley, between Hughes and Commonwealth glaciers.
