Optical study of surface melting on ice
WebAbstract. Melting of the Greenland Ice Sheet (GrIS) is the largest single contributor to eustatic sea level and is amplified by the growth of pigmented algae on the ice surface, which increases solar radiation absorption. This biological albedo-reducing effect and its impact upon sea level rise has not previously been quantified. Here, we combine field … WebDec 22, 2024 · The spatial distribution of surface meltwater in the study region is hence closely controlled by melt–albedo coupling between exposed bedrock, blue ice and surface melting (Kingslake et al., 2024). On both grounded and floating sections of the study region, lakes typically form in the same location on an annual basis (Fig. 6).
