Ocean Acoustics
Due to construction work in the sea, shipping, and gas and oil extraction, the oceans are becoming increasingly louder. A comprehensive international study has now shown that this n

Sediments deposited [...] ability to predict sedimentation processes is limited especially in the North Sea. Additionally, anthropogenic activities, such as bottom trawling, can alter POC sedimentation, releasing the deposited carbon

today we will provide some information on the work of our colleagues here on board assessing anthropogenic impacts on the marine ecosystem on our way from Bremerhaven to Fram Strait (and back) and at

a research team led by Alfred Wegener Institute scientists investigated what long-term impact anthropogenic climate change will have on ocean eddies and their far-reaching effects. Using climate model
