The native European oyster is to be re-established as a former key species in the North Sea and adjacent European seas in order to restore species-rich reef structures as extensively as possible. More

The overarching goal is to facilitate a politically, socially and ecologically acceptable [...] CONMAR is to provide information on the distribution and condition of munitions in the German North Sea and Baltic Sea and to generate an understanding of the release and dispersal of explosives in water and

Arctic. Due to rising water temperatures, many Arctic fish species are retreating farther and farther north, while species from more temperate latitudes are increasingly being sighted off the coasts of Greenland [...] Institute have now analysed scientific publications on the ecological impacts of climate change in Arctic seas released in the past ten years. Their findings: the shifting habitats have affected entire biotic

To what extent does polymetallic nodule mining impact the ecosystem in the deep sea? This is what the MiningImpact expedition SO295 with the research vessel SONNE is investigating for the next two months [...] months in the exploration contract areas of the Clarion-Clipperton Zone in the North Pacific. During the collection of polymetallic nodules, the bio-active layer of the seabed is removed and the sediments

From 2024, visitors can expect a unique exhibition covering everything from the history of the North Sea to the future of marine research. At the heart of the exhibition is an 80,000-litre aquarium showcasing

the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from [...] to fundamentally impact the local symbiotic communities, from the water’s surface down to the deep seas. As the authors recently reported in the journal “Ecological Indicators”, that’s precisely what happened

an ice shelf is born. Meteoric ice floats on sea water because of its density being smaller (910 kilograms per cubic meter) compared to the density of sea water (1028 kilograms per cubic meter). An ice [...] part of an ice sheet and floats on the ocean, but it rests on the sea floor at its fringes and on embedded islands. Contact with the sea floor slows down the seaward movement of shelf ice and thus the ice [...] formed by intensive sea ice formation in coastal polynyas (large ice-free area near the coast) flushes the ice shelf cavity (Fig. 2), causing melt rates less than 1 meter per year. Sea water at the surface

To make area-based statements about the sediment properties of the seabed, we employ [...] Water Meets Land – Coastal Hydrography and Geology The Wadden Sea forms a transitional habitat between land and sea. High tidal amplitudes, shallow water depths, strong winds, and rivers discharge create [...] beneath the seabed and give us the opportunity to study the historical development of the very young North Sea on geological time scales. These methods help to visualize and analyze glacial surfaces and ancient
