Abstract

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.

Description

1. File List A. Filename: NDS_chl.csv Short description: chlorophyll-a concentrations across snow treatments and nutrient treatments for the 21 day experiment and 25 day experiment. B. Filename: 16S_Sequences zipped folder Short description: folder containing 8 fastq files for 4 paired-end 16S V4 amplicon sequencing samples. Files are named based on their nutrient treatment replication and are for the 25 day experiment. C. Filename: 18S_Sequences zipped folder Short description: folder containing 8 fastq files for 4 paired-end 18S V9 amplicon sequening samples. Files are named based on their nutrient treatment replication and are for the 25 day experiment. 2. Relationship between files: The main dataset is "NDS_chl.csv" and has chlorophyll-a concentrations for all NDS deployed in the experiment. The 18S_Sequences and 16S_Sequences are the 18S and 16S data from a subset of NDS.
