Ocean Acidification
In November 2017, the German research network on ocean acidification BIOACID (Biological Impacts of Ocean Acidification) reaches its conclusion after eight years of extensive in [...] from 20 German institutions clearly indicate that ocean acidification and warming, along with other environmental stressors, impair life in the ocean and compromise important ecosystem services it provides

implementation of sustained observations in both the Arctic and Southern oceans and the development of a truly novel finite-element ocean model. AWI is in the unique position to make the long-term commitments [...] has generated novel insights into the role of the biological pump in climate control. AWI ocean acidification research is world class, as also reflected by top-ranking publications, and innovative experimental [...] permafrost and carbon turnover in the coastal, shelf and deep sea environment WP 6: Ocean warming and acidification: organisms and their changing role in marine ecosystems Topic 2: Coastal change WP 1:

marine organisms in the fjords of Spitsbergen react to increased UV radiation and increasing ocean acidification. The geosciences, on the other hand, focus on changes in permafrost soils and glacier systems [...] Without Borders in the Arctic The Svalbard archipelago is located east of Greenland in the Arctic Ocean. The archipelago is home to Ny-Ålesund, one of the northernmost settlements in the world. Depending

vulnerable to ocean acidification. The increasing amount of carbon dioxide in the atmosphere leads to an increased absorption of CO2 in the cold waters of the polar oceans and enhances the acidification there

Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent their [...] recently demonstrated. If this comes to pass, it could have far-reaching consequences for life in the ocean, as they report in the journal Nature.

Stefan Hendricks) The Arctic Ocean Unlike at the southern tip of the planet, in the High North there is no continent, only an ocean. These waters, also known as the Arctic Ocean, extend to the northern coasts [...] Arctic Ocean is the smallest in the world. Moreover, it’s not particularly deep: just 987 metres on average, though 5,669 metres at its deepest point. Its only deep-sea connection to other oceans lies in [...] freshwater is flowing into the Arctic Ocean. This freshwater lies like a lid atop the deeper, saltier water layers. As a result, fewer nutrients from the ocean’s depths rise to the surface, while less

The main goal of our arctic research is to understand and follow seasonal and interannual fluctuations [...] Key aspect is to measure the changes of all parameters in relation to rise in temperature and acidification.
