| Summary: | This dataset consists of 75 destructive ice surface samples for which glacier algae cell counts were undertaken. The sample locations were distributed randomly over a 250 X 250 m area. Funding was provided by the NERC standard grant NE/M021025/1. : On 26 July 2018 we cast a random 75-point sampling grid over our UAS flight area defined in "Multi-spectral unmanned aerial system imagery, UPE_U, north-west Greenland, July 2018: Levels 2 (ground reflectance) and 3 (broadband albedo and surface type classification)". We used a trowel to scrape the snow away to reveal the bare ice surface beneath for sampling. Samples were made by cutting a 30 X 30 X 2 cm volume out using a metal ice saw and trowel and transferring into a sterile Whirl-Pak bag which was immediately placed in the dark to melt over a 24 hour period at ambient air temperature. Following melting, samples were homogenised, sub-sampled into Falcon tubes and fixed with 2% final concentration gluteraldehyde. Samples were then returned to laboratories at the Universities of Sheffield and Bristol for counting by microscopic haeomcyometry. Full details of the enumeration protocols used are in Williamson et al. (2018, FEMS Microbiology). : Good. |
