UN Decade of Ocean Science Spotlight on the Ocean It’s a world full of riddles: though the ocean shapes the face of our ‘blue planet’, covering 70 percent of its surface, we still know far too little about [...] safety. In the context of the Decade, all of this knowhow is to be made available worldwide. And last but not least, the goal is to raise awareness for the economic, social and cultural value of the ocean; [...] network that investigates open research questions and develops solutions for the preservation and sustainable use of the ocean. Its motto: “The science we need for the ocean we want”. After all, intact ocean

The density of the nests and the size of the entire breeding area suggest a total number of about 60 million icefish [...] breeding at the time of observation. These findings provide support for the establishment of a Marine Protected Area in the Atlantic sector of the Southern Ocean. A team led by Autun Purser from the Alfred [...] Fascinating discovery
Near the Filchner Ice Shelf in the south of the Antarctic Weddell Sea, a research team has found the world's largest fish breeding area known to date. A towed camera system ph

We have proof of his meticulousness in that we possess his personal copy of the first edition of his book “The Formation of Continents [...] elements in the Earth’s crust. He called one of them sial and the other sima. Wegener assumed that the oceans were composed of a heavier material than the continents. He thus presumed that the lighter continents [...] continents float on the heavier subsurface, like ice floes on the water. That was the core of his idea! It was associated with the concept of so-called isostasy. This says land bridges or the like couldn’t come

The ocean takes up about one quarter of the excess CO2 [...] carried out in this remote region of the world’s oceans.
