Whale hell looms in Massachusetts
The first of the monster offshore wind arrays is ready to roll, with construction to begin in May. The acoustic hammering on the whales and other sea critters will now escalate from sonar survey blasting to the incredible noise of pile driving. Each huge wind tower sets on an enormous monopile that has to be driven into the sea floor. The project bears the happy name Vineyard Wind but there is no vineyard. Here is how they put it: “Vineyard Wind is currently building the nation’s first utility-scale offshore wind energy project over 15 miles off the coast of Massachusetts.” There are 62 enormous wind towers, each among the world’s biggest at 13 MW. >click to read< 12:54
Exposure to pile driving noise associated with construction of docks, piers, offshore wind farms, cause squid to exhibit strong alarm behaviors
“This study is the first to report behavioral effects of pile driving noise on any cephalopod, a group including squid, cuttlefish, and octopuses,” says lead author Ian Jones, a student in the Massachusetts Institute of Technology-Woods Hole Oceanographic Institution Joint Program in Oceanography. Jones and his colleagues in the Sensory Ecology and Bioacoustics Lab at WHOI exposed longfin squid (Doryteuthis pealeii) to pile driving sounds originally recorded near the construction site of the Block Island Wind Farm in Rhode Island. >click to read< 11:52
