An important part of the McMurdo Long Term Ecological Research (LTER) project is identifying patterns and movements of nutrients in perennial ice-covered lakes. This data set addresses this core area of research and quantifies macronutrient concentrations found at specific depths in McMurdo Dry Valley lakes.
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.
