Amplicon sequencing dataset of that profiled Bacteria (16S ssu rRNA gene) in different closed cryoconite holes on the Diamond Glacier and Koettliz Glacier (Southern Victoria Land, Antarctica). meer
Access through the ice lid was accomplished using a 50-mm diameter Kovacs ice drill, which was cleaned between each hole with antibacterial wipes. Water samples were collected directly into three 60-mL centrifuge tubes for determination of major ions and isotopes, using a manual vacuum apparatus. A sample (1 L) was collected by vacuum into an acid-washed PVC bottle. A subsample (100 mL) filtered (Whatman GF/F) into an acid-washed polyethylene bottle and frozen for later nutrient analysis. Study Extent: Cryoconite holes were sampled in the austral summer (December–January), during Antarctic field seasons between2010 and 2013 at the Koettlitz Glacier and Diamond Glacier (Southern Victoria Land, Antarctica). Only cryoconite holes with a diameter of greater than 30 cm (which were typically also greater than 35 cm deep) routinely contained liquid water, and were targeted for sampling. Selection was based on replicate N+1 being the next encountered appropriately sized closed cryoconite hole encountered in a random direction from replicate N. Method step description:
