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

Our mission is to characterize the implications of anthropogenic underwater noise on marine invertebrates and ecosystems The increase of anthropogenic underwater noise (AUN) has altered marine acoustic
