has so far only been analysed in theory and in smaller pilot projects in the German Bight of the North Sea. With the help of an experimental implementation of co-use, this project aims to address gaps in [...] consequences and incentives together with the most important actors. In addition, the link between sea and land under the co-use concept is to be defined practically by means of a local marketing strategy

sustainable and multifunctional use of marine areas in heavily used oceans on the example of the North Sea Objectives: The project aims to create a multi-use road map as a tool for the future use of marine [...] multi-trophic aquaculture (IMTA)-system. Model organisms are fish (turbot Scophthalmus maximus , sea bass Dicentrarchus labrax ) as fed aquaculture candidates, bivalves (mussels Mytilus edulis , oysters

on a previously unimaginable scale. One of the most obvious changes is the rapid decline in Arctic sea ice over the last two decades. This has a direct impact on Arctic microorganisms as more light is available [...] new production. In addition, ocean warming is leading to changes in the winter mixed layer in the North Atlantic, which has reduced the amount of silica entering the Arctic Ocean in recent decades. This
