Data for Reduced snow and increased nutrients show enhanced ice-associated photoautotrophic growth using a modified experimental under-ice design

We modified an existing stream method to create a novel under-ice approach by deploying nutrient diffusing substrates (single nutrient amendments, nitrogen or phosphorus; combined enrichment of nitrogen and phosphorus) under two different light scenarios (snow covered, reduced light; snow removed, increased light) near the water-ice interface to mimic the habitat of ice-associated photoautotrophs. The data associated with the nutrient diffusing substrates are: chlorophyll a concentrations, 16S, and 18S.
