Nöthig Research The Arctcic Ocean reacts more sensitive to Gloabal Change than other oceans. Sea ice strongly decraeses, temperatures rise at least twice as much, acidification and, the influence of warmer [...] mainly as part of projects such as FRAM, LTER HAUSGARTEN, PEBCAO in different regions of the Arctic Ocean. 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.

life in the ocean, in particular carbon, nitrogen, phosphorus and silicon, as driven by physical, biological and chemical processes. Marine biogeochemical cycles play a relevant role in ocean productivity [...] system. The elements of the biogeochemical cycles are considered essential ocean variables (EOV) as defined by the Global Ocean Observing System. In order to study biogeochemical cycles, we need to measure [...] alkalinity, which provides information about the buffer capacity of seawater, relevant to study ocean acidification. The facility is divided in three modules based on scientific topics, as follows. Nutrients:

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

Yet the deep sea is not a habitat fully separated from the surface; it is already undergoing dramatic changes in response to warmer water, ocean acidification and environmental [...] the so-called mid-oceanic ridges – volcanically active mountain chains that usually extend one to three kilometres above the seafloor and can be found in all (of) the world’s oceans. With a total length [...] standards. For another, food is harder to come by. The central Arctic Ocean is largely covered with ice and – unlike the Antarctic’s Southern Ocean – surrounded by landmasses. Exchanges with the Atlantic and Pacific

important the ocean is for us: “The global ocean is the life insurance of our planet. It has greatly slowed down global surface warming. However, this service comes at a high cost: The ocean is acidifying [...] and climate change are putting pressure on natural sinks on land and in the oceans. For example, in the past decade, the oceans have absorbed 10.5 metric gigatons per year on average, or 26 percent of overall [...] conditions have reduced the oceans’ capacity to absorb CO2 by roughly 6 percent,” says Prof Judith Hauck, an environmental researcher at the AWI, who coordinated the content on the ocean sinks.

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
