Scientific Research Marine Conservation Anthropogenic Noise Pollution

The article discusses a study published in the Journal of Experimental Biology regarding long-finned pilot whales in the Strait of Gibraltar. It explains how human-made noise, particularly from shipping, forces these whales to increase the volume of their calls to communicate.
