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
