If carbon dioxide concentrations in the atmosphere and thereby in the ocean continue to rise, this could favour the mass development of toxic algae, with far-reaching consequences for the

2013). Besides water temperature increase, expanding ocean acidification will pose another threat to pelagic and benthic life in the Arctic Ocean (e.g. Bates et al., 2009; Lischka & Riebesell, 2012; AMAP [...] Changing Arctic Ocean) focusses on the plankton community and the microbial processes relevant for biogeochemical cycles of the Arctic Ocean. This research focus is acknowledging that the Arctic Ocean has gained [...] In addition, the chemical equilibrium and the elemental cycling in the surface ocean will alter due to ocean acidification. These environmental changes will have consequences for the biogeochemistry and

and carbonate preservation in the deep ocean and the impact of ocean acidification on the ocean.

Currently the oceans provide roughly 20% of the protein consumed by humans. Emerging countries, with a huge need for ocean resources [...] in ocean education, increases the capacity and knowledge required for ocean observation in fragile shelf seas, provides new training programmes in emerging countries highlighting sustainable ocean needs
