Marine researchers find trawling noise risk to protected mammals


Trawling introduces disturbing noise to deeper waters around submarine canyons and marine mammal habitats

The noise of bottom trawling in or near underwater canyons can disturb protected mammals such as fin whales and beaked whales in important feeding grounds and along migratory paths, researchers have revealed.

The team based with iCRAG, the SFI Research Centre for Applied Geosciences in NUI Galway’s Ryan Institute, used hydrophones to record the impact of working trawlers on the marine environment in two surveys in the Irish Sea and Celtic Sea. MORE
