WebMar 23, 2024 · In this study, we collected surface water samples from the Southern Ocean off Prydz Bay during and after sea ice melting season (SIM). After removing the particles using 0.7-μm pore size filters, we measured the concentration of dissolved organic carbon (DOC) and the composition of dissolved organic matter (DOM) by using the total organic ... WebOct 25, 2024 · Surface melt is an important driver of ice shelf disintegration and its consequent mass loss over the Antarctic Ice Sheet. Monitoring surface melt using satellite remote sensing can enhance our understanding of ice shelf stability. However, the sensors do not measure the actual physical process of surface melt, but rather observe the …
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). WebJul 1, 2009 · Ice crystals have been studied at the air interface mainly to study the properties of the quasi-liquid layer at the ice-air interface (19)(20)(21) (22) and friction between the AFM tip and the ice ...

WebAntarctica’s northern George VI Ice Shelf experienced record melting during the 2024-2024 summer season compared to 31 previous summers of dramatically lower melt, a CU Boulder-led study found. The extreme melt coincided with record-setting stretches when local surface air temperatures were at or above the freezing point. easton synergy 200 ice skatesWebAbstract. 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.
