Radiometric and hydrologic analysis of radar-sounding data is consistent with a reflection from a subglacial groundwater table• Dual radiometric constraints indicate a layer of either debris-laden ice or fractured bedrock above the subglacial groundwater table• This first detection of a subglacial groundwater table was enabled by favorable local geology

the ocean colour derived open water season is lengthening by up to 2 days per year. Winter ocean color satellite coverage starts to degrade at 52°N for the Northern Hemisphere. Analysis suggests signicant decreasing trends in winter cloud cover in sub-Arctic waters of the northern Atlantic

thin ice and the wide bandwidth radar system

volcanic ash

which lowers surface fCO2w • Air-sea CO2 fluxes are biased when estimated using fCO2w observations from the sub-surface (6 m depth) in sea-ice melt areas • Summertime sea-ice melt potentially results in a 6%–17% (with high uncertainty) underestimate of annual Arctic Ocean CO2 uptake

with living biomass a minor fraction • Low‐light and high detrital biogenic silica promotes net dissolution rather than net production
