Answer:
The underwater noise that is produced during construction activities, mainly in the driving of piles and monopiles affects marine life, especially marine mammals.
Loud underwater noises also confuse marine mammals that rely on their own sonar to identify large objects in the water. Whales and dolphins use echolocation or “biosonar” systems to locate predators and prey.
In such circumstances, collisions may result from marine mammals, especially whales, being unable to locate and avoid ships because ships emit sounds over a wide range of frequencies and in all directions.
A number of factors affect the response of marine mammals to sounds in their environment: the sound level and other properties of the sound, including its novelty; physical and behavioral state of the animal; and prevailing acoustic characteristics and ecological features of the environment in which the animal encounters the sound.
Noise has deafened fish, produced dramatically reduced catch rates, caused stress responses, and interfered with fish communication, schooling, and possibly the selection of suitable habitat.
