For the past 25 years, the Alfred Wegener Institute has operated a long-term observatory in the Arctic deep sea: the HAUSGARTEN. Located between Greenland and Svalbard, it is where researchers investigate [...] investigate natural and climate-change-related changes in a polar, marine ecosystem – from the ocean’s surface to the seafloor, 5,500 metres below. Many of the observatory’s stations are located below the sea

in the Arctic is expected to rise due to the increase in available light as the sea ice melts, however the role of nutrient limitation is less understood. The inflow of silicic acid into the Arctic Ocean [...] biomass was actively taking up nutrients (Fig. 4). Light limitation is a key driver of central Arctic Ocean primary productivity, regulating C and N uptake, with increasing light being a potential stimulant [...] Impact of sea ice decline and changing silicic acid availability on Central Arctic primary productivity Antonia Thielecke1, Jeffrey Krause2, Natasha Bryan1, Lena Eggers1, Mar Fernández-Méndez1 1Alfred

Research aircraft from the Alfred Wegener Institute have been surveying the ice-covered Arctic Ocean for 30 years. The immense effort of the past 52 expeditions has paid off: 40,000 km of measurement data [...] aeroplane- and helicopter-based measurement series in the world that has been carried out in the Arctic over such a long period. Currently, two Basler BT-67 aircraft are in operation: the Polar 5 and Polar

The unique geometry of the Arctic—surrounded [...] the Arctic Ocean with hydrographic observation lines (Figure 1). A method to treat the Arctic as a single box bounded by hydrographic lines and land has been developed recent years. This pan-Arctic approach [...] monitor the major oceanic heat and FW exchanges between the Arctic Ocean and surrounding Oceans?
