increase of CO2 in the ocean upsets the carbonate chemistry of the ocean and causes the waters to become more corrosive. The images indicate that all of the Southern Ocean surface waters south of 60°S and [...] may, for instance, alter the behaviour of an organism. An important question at the end of the previous CBD report on ocean acidification was the determination of so-called tipping points – has research been [...] that was previously the case in the history of the Earth. The question is therefore whether the animals can hold their own at this speed and adapt fast enough. Thus far we have studied the short-term adaptability

sampling of the Kerguelen Plateau in the southern part of the Indian Ocean. The Kerguelen Plateau rises up 2000 m above the surrounding seafloor and hence forms an obstacle for the flow of the Antarctic [...] chronicle of Cenozoic climatic and oceanographic changes in the southern Indian Ocean Located in a key region in the southern Indian Ocean the complex topography of the Kerguelen Plateau, one of the world’s [...] caused by the tectonic development of the Kerguelen Plateau as well as the opening of the Tasman Gateway, the Drake Passage and major global climatic changes. In the Kerguelen Plateau region all of these changes

The fragmentation of the Manihiki Plateau poses the question, whether distinct phases of magmatic or tectonic processes led to the deformation of the Manihiki Plateau [...] suggested that the Ontong-Java Plateau was connected to the Manihiki Plateau at the Western Plateaus and drifted towards the west. Overview map of the Pacific Ocean in the vicinity of the Manihiki Plateau [...] development of the Manihiki Plateau We try to unravel the relationship between the two largest sub-provinces of the Manihiki Plateau, the Western Plateaus and the High Plateau, which are separated by the Danger

gallery gives an insight to the research work and the living conditions on Muostakh, reaching from the arrival, the sampling of ice wedges, the measuring of the island, to the use of driftwood and a special [...] Coastal erosion The Atlantis of the Arctic The clock is ticking for Muostakh Island: another 100, 140, maybe even 200 years, then the small isle off the coast of Siberia will disappear from the map. Then, where [...] where today 15-metre-tall bluffs of ice-rich, frozen ground still defy the currents of the Lena River and the waves of the Laptev Sea, there will be nothing left. The cause: coastal erosion. Every year

Snapshots of life at the station – according to C [...] Research at the furthest reaches of civilization Modern laboratory facilities, a large fleet of vehicles and a stable Internet connection: located at the heart of the Siberian tundra, the Samoylov research [...] Morgenstern Getting there Samoylov Station is located in the middle of the Lena Delta. On the map it only looks like a tiny dot amidst the expanse of the Siberian tundra, far from any cities, airports or motorways

From [...] And the list of superlatives goes on: the coldest water masses in the world circulate below the ice shelf. With a temperature of minus 2.5 degrees Celsius, they only remain liquid because of the high [...] heat from the ocean could pose a threat to the largest ‘ice brake‘ in the Antarctic. In the past, climate researchers weren’t very worried about the Filchner-Ronne Ice Shelf. The massive sheet of ice, which

The glaciers at the edge of the inland ice are particularly affected [...] bottom of the glacier to melt at a high rate. As part of my PhD thesis, I have been examining the question of how this warm Atlantic water is transported from the Fram Strait to the 79°North Glacier. But

above all, the climatic shift has opened the door for the commercial exploitation of the Arctic. Thanks to changes in the global climate, the polar reaches will be more heavily frequented in the future. With [...] weather stations in the populated regions of the Earth has been significantly expanded since the early 20th century, the polar regions – which are in complete darkness six months of the year and where operating [...] capacities for the polar regions, in 2013 the World Meteorological Organization (WMO) launched a long-term project to improve forecasting (the Polar Prediction Project). In the context of the project, in

Researchers use this very [...] estimate the sea ice thickness and the volume of the snow cover along the ship's route. Temperature sensor A sensor chain is collecting data about the temperature and heat conductivity of the surrounding [...] Methods of the AWI sea ice physicists - an overview In action on an ice floe When will the Arctic ocean be ice free? Why did the sea ice cover of the Southern Ocean grow during the last years? And how
