Previous research suggests that pelagic food webs in the Central Arctic Ocean (CAO) are highly dependent on ice-associated food sources (Fig. 1), but how prevailing trophic [...] waters, riverine input and marine traffic will bring more anthropogenic pollutants, even to remote Arctic regions, where they are entrained in water and sea ice, and transferred along the marine food chain

Consider a summer day somewhere in Europe with an Atlantic ocean breeze, and compare it to a day influenced by winds blowing from the continent. The latter will tend [...] more strongly affected by climate change, simply because the continents warm more strongly than the oceans. Can we be more specific? Yes! By using a climate model in a special way, where the winds are forced

Though our knowledge of the sea ice in the Arctic and Antarctic [...] data are needed in order to validate our computer models and depict the realities of sea ice in the Arctic and Antarctic as precisely as possible using computers. If we succeed in this detail work, we’ll

The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in

However, not all the Atlantic [...] In the last few decades, the Arctic sea ice has receded ever further, including increasingly in winter when the extent of sea ice is at its most prominent. One of the main drivers of this development is
