During HE607 it is planned to visit the again the wreck site of the submarine [...] Bremerhaven – Bremerhaven The aims of the cruise HE635 are cross disciplinary investigations of munition dumping sites in the southern German Bight and the test of new underwater crawler for munition monitoring [...] (e.g., patterns of coastal runoff) and chemistry to reveal terrestrial and marine sources of nutrients, OM, freshwater, and the distribution of greenhouse gases of the PCES.

The sea bass can tolerate temperatures in the North Sea, but the average temperature of 10 ° C in [...] flow velocities of 5-10 cm s -1 for optimal nutrient and CO 2 exchange on the surface of the thalli, as well as for the reduction of growth of epiphyts. In strong currents, the thalli of macroalgae become [...] escape through the mesh or other materials. Cod is one of the species with the highest rate of the escapees, which can have a negative impact on the wild population by cross-breeding. The extreme temperature

learning more about the ecosystem of the deep and how it reacts to human activities at the surface is indispensable. Antarctic sponge ground (Photo: Luisa Federwisch) The landscapes of the deep sea The deep sea [...] in 150 years of deep-sea research we have only managed to take a closer look at a small fraction of this ecosystem; in fact, we know more about the dark side of the moon than we do about the ocean depths [...] considers all waters beyond the reach of light from the surface to be part of the deep sea. This lightless deep sea encompasses ca. 88 percent of the global oceans and begins at a depth of 200 metres. Consequently

Within the AWI-HZG research program PACESII, the CSD is located in Topic 2 (Fragile Coasts). The Centre for Scientific Diving is also the home of the working group "In situ ecology" which is part of the AWI [...] important for the protection of our coastlines. A good example for this development is the North Sea, were more than 80 % of the coastline is already artificially protected. In 2010, the Centre for Scientific [...] Scientific Diving of the AWI has installed an underwater experimental field North of Helgoland called MarGate to study the impacts of artificial structures on the demersal fish and macroinvertebrate communities

that the theory is correct. Wegener got profoundly involved in the matter. 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
