Abstract This work presents the results of physical and biological investigations at 27 biogeochemical stations early winter sea ice in Ross Sea during 2017 PIPERS cruise. Only two similar cruises occurred past, 1995 1998. The year was a specific year, that growth Central considerably delayed, compared to previous years. These conditions resulted lower thicknesses Chl- burdens, as those observed cruises. It also different structure sympagic algal community, unusually dominated by Phaeocystis...
Abstract Storfjorden, Svalbard, hosts a polynya in winter and is an important source region of Brine‐enriched Shelf Water (BSW) that, if dense enough, feeds the Arctic Ocean deep water reservoir. Changes BSW production may thus have far‐reaching impacts. We analyze mass distribution circulation Storfjorden trough south it, Storfjordrenna, using hydrographic sections occupied July 2016, following characterized by lowest ice coverage recorded Barents Sea. These observations reveal unusual...
A paradox is commonly observed in productive sea ice which an accumulation the macro-nutrients nitrate and phosphate coincides with of autotrophic biomass. This requires a new conceptual understanding biogeochemical processes operating ice. In this study, we investigate using three time series Antarctic landfast ice, massive algal blooms are reported (with particulate organic carbon concentrations up to 2,600 µmol L–1) bulk nutrient exceed seawater values 3 times for 19 phosphate....
Abstract Given rapid sea ice changes in the Arctic Ocean context of climate warming, better constraints on role CO2 cycling are needed to assess capacity polar oceans buffer rise atmospheric concentration. Air-ice fluxes were measured continuously using automated chambers from initial freezing a cover until its decay during INTERICE V experiment at Hamburg Ship Model Basin. Cooling seawater prior formation acted as sink for CO2, but soon first crystals started form, turned source which...
