Scholz (Photo: Alfred-Wegener-Institut) Daniel Scholz - Within the FRAM project (Frontiers in Arctic Monitoring), my responsibilities are the development, deployment, calibration and data validation of [...] to monitor nutrients and carbonate chemistry parameters in the Fram Strait and the Central Arctic Ocean. To monitor such parameters in the ocean, it is common practice to analyze discrete water samples

biogeochemical sensors distributed over a certain area (e.g. in the Fram Strait or in the Weddell Sea) over a period of several years or even decades. This has been done at the AWI for a long time and forms

Today, the HAUSGARTEN observatory consists of 21 monitoring stations at depths of between 250 [...] responses in the deep-sea ecosystem. This can already be seen in Fram Strait between Svalbard and Greenland, where the composition of the phytoplankton has changed. Whereas, in past decades, more diatoms [...] untouched by time. Even in remote regions like the floor of Fram Strait between Greenland and Svalbard, the number of these large bits of litter has grown substantially in recent years. Moreover,

the overall diversity of the entire plankton community of the Fram Strait (Arctic) is assessed. This data is then applied to forecast future scenarios of Arctic planktonic biodiversity. Recommendations

different test campaigns are planned, including a shorter drift in Fram Strait in summer 2025 and winter experiments in Svalbard. Tara Polar Station in Lorient, France, in April 2025 (Photo: Marcel Nicolaus
