Offshore Wind


Substrate-Borne Vibration and Particle Motion Impact on Atlantic Fisheries Species


Atlantic fisheries species generate over $20 billion annually for the New England economy across commercial and recreational sectors. Last year, Massachusetts and Rhode Island announced the largest offshore wind selection in New England history, 2,878 MW, spanning 100 miles of coastline. Some fisheries communities have responded with concern that key fish species will be displaced, with no guarantee that they will return to local estuaries. Other scientists have argued that species will just swim away from the noise. While offshore wind acoustic research has primarily focused on marine mammals and pelagic species, a key gap has been the response of benthic fish and invertebrates who spend their lives in the substrate and are particularly sensitive to particle motion and substrate-borne vibration. In this ongoing work, we are investigating changes in physiology related to respiration rate, startle response, and temporary hearing loss in the summer flounder, heart rate patterns in the American lobster, and ramp-ups as a possible soft-start technique. This work is still in the data analysis phase, but will present key estimates of how species will be affected by offshore wind construction along the East Coast. Collaborator
