Arctic Sea Ice
The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by

Arctic Ocean
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
