to various factors such as warming, nutrient deficiency or ocean acidification, by focusing on one of the most sensitive areas on Earth, the subarctic and Arctic Ocean. Thereby, we contribute to [...] emission scenarios. Firstly, as a greenhouse gas, rising CO 2 causes ocean warming: temperatures of the surface waters have already increased by 1.1°C on average, while some regions like the Arctic Ocean [...] from CO 2 : As much of the anthropogenic CO 2 is taken up by the ocean, concentrations of CO2 and bicarbonate increase while the concentration of carbonate ions and the pH decrease, also known as 'Ocean

biological carbon pump) are linked in the present-day and future Arctic ocean, as well as to which extent this relationship is driven by differences between functional groups (i.e. species shifts) 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 obtained e.g. by rosette [...] sensors are designed and calibrated to perform in temperate oceans and thus, the Arctic represents a challenging environment that lies outside the configuaration of most sensors. Hence, in order to

fast things changed, what forces drove them, how ice sheets and oceans responded – we would gain something invaluable: a longer perspective on what is possible. But how do we read a past that left no [...] – a measure of ocean acidity that is closely linked to atmospheric CO₂ levels. These are just two of the signals we work with, each opening a different [...] water masses from the Atlantic are pushing further north into the Arctic Ocean through the Fram Strait. This is a recent and ongoing phenomenon, and understanding its pace and extent requires archives with

marine biogeochemical model REcoM. When embedded into a large-scale ocean circulation model, we can project the future of the oceanic carbon sink, the conditions for marine life, and put a specific focus [...] preserved in biological archives such as foraminiferal shells or Arctic coralline algae, the group works to recover information about past ocean and climate conditions.

I strongly believe that a holistic understanding of the Arctic Ocean ecosystem is essential in view of future management and conservation strategies to preserve this unique and fragile ecosystem [...] the acoustic occurrence of baleen whales in the Arctic Ocean. This region is of special concern due to strong ongoing environmental alterations triggered by climate change, such as sea-ice
