Another topic will be the development of the necessary [...] feed on other crustaceans as well. In addition to the growth rate of the animals, we also focus on the digestibility of the feed. The prototype of the trap has been in Belgium since 2019 (Photo: Alfre [...] Successful control of invasive mitten crabs with an innovative trap concept The mitten crab is on the IUCN's list of the world's 100 most dangerous invasive species. In Germany, the crab is found in large

Over the decades, layer after layer of snow [...] content, the staff can determine when there were past volcanic eruptions. Another question is how the temperature developed in e.g. the Antarctic hundreds of thousands of years ago. In this regard, the water’s [...] and head of the ice-core drilling group in Bremerhaven. Since they can’t simply turn back the clock, the scientists rely on laborious measuring methods to test the ice cores. These rods of glacier ice

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

This state may change if the position and strength of the Antarctic Circumpolar [...] focuses on recording the history of the position of the ACC and major SO fronts, the status of Antarctic Bottom Water (AABW) formation today and in the past, as well as a range of additional hydrographic [...] series of 3D-distributions in the water column of the Arctic Ocean. The selected stations are based on locations and variables that have been observed in the past. The quasi-synoptic survey of the CAO and

Aims of this Symposium There are five major aims of this symposium

The instrumental record is only a snapshot of our climate record. Two recent advances allow a deeper use of the paleo-record: (1) the increased [...] itut) Lake & Sea ice algae Lake & Sea-ice algae The seasonal extent and properties of Arctic ice on land and in the ocean determine the efficacy of the albedo feedback mechanism causing arctic climate

The Centre for Scientific Diving is also the home of the working group "In situ ecology" which is part of the AWI [...] for humankind with more than half of the world’s population living less than 50 kilometres away from the sea.
