BOEM and NOAA partnered to deploy drifting acoustic recording buoys to collect acoustic data from cetacean species and ocean noise in these offshore waters. In addition to successful deployment of 90 buoys in and near the proposed Wind Energy Areas (WEAs), NOAA analyzed archived drifting acoustic data from two previous surveys (CCES 2018, PASCAL 2016) for soundscape and the presence of marine mammal species. 1365410 U.S. Department of the Interior, Bureau of Ocean Energy Management, Environmental Studies Program https://doi.org/10.13039/100012475 M20PG00013 10.67297/9A1E50 https://boem.gov/awardpages/100304
