Black and Bloom Work Package 2: Particulates Black and Bloom is a research project, funded by the UK Natural Environment Research Council (NERC), that aims to unravel how dark particles (black) and microbial processes (bloom) darken and accelerate the melting of the Greenland Ice Sheet. The data has been collected during two distinct field seasons (July 12 – August 18, 2016 and June 1 – 28, 2017). Ten-day particle dispersion calculations made using the FLEXPART model initiated from the ground site (67.07° N, 49.38° W 1073 m AMSL) in the ablation zone in southwest Greenland, approximately 35 km from the ice sheet margin. The outputs were collated into animations, which are in this folder
