Underwater acoustic, turbidity, biofouling, and corrosion monitoring were also conducted at the offshore Virginia location after the two monopile turbines became operational. To facilitate the presentation and review of the large quantity of observations and data generated during the study, this information was organized into three standalone volumes: 1) construction noise monitoring; 2) operational noise monitoring; and 3) turbidity, biofouling, and corrosion monitoring during the operational phase. 1380785 U.S. Department of the Interior, Bureau of Ocean Energy Management, Environmental Studies Program https://doi.org/10.13039/100012475 M0118F0006 10.67297/9A1E21 https://boem.gov/awardpages/100257
