Description: This layer represents transects from New England Aquarium aerial surveys conducted from 2011-2021. These surveys focused on all marine megafauna visible from a plane (excluding birds) and were comprised of ten north-south transects evenly spaced at approximately six nautical miles (nm). Eight survey options are available: each option shifts all 10 transects 0.75 nm east or west, but maintains the six nm spacing between transects. One of these options was selected at random before each survey. The surveys have been funded by the Massachusetts Clean Energy Center (MassCEC), the Bureau of Ocean Energy Management (BOEM), and most recently by offshore wind development companies. In some years, surveys were coordinated with partners that conducted boat-based oceanographic sampling to assess the physical and biological characteristics of the study area. <br/> <br/> The surveys show that many species of marine megafauna use the study area in high numbers. The most recent surveys show an increased presence of right whales in all seasons and a decrease in the presence of other large whales, such as humpbacks. There also appears to be a shift in presence of all large whales towards the eastern side of the survey area. Continued surveys are needed to determine the consistency of these patterns. Continuing this 10-year time series of consistent aerial survey data also represents a unique opportunity to detect potential short-term effects of turbine construction on US marine species and develop solutions for mitigating these effects. <br/> <br/> View the most recent survey report: <a href="https://files-cdn.masscec.com/uploads/attachments/BOEM%202021-054%20NEAq%20MACEC%20BOEM%20Large%20Pelagics%20Campaign%206A%20Final.pdf" target="_blank">Megafauna Aerial Surveys in the Wind Energy Areas of Massachusetts and Rhode Island with Emphasis on Large Whales: Summary Report Campaign 6a, March 2020 - October 2020</a>.
