\nIn June 2021, the Bureau of Ocean Energy Management (BOEM) convened a workshop titled \"Improving monitoring, data consistency, archiving, and access for improved regional integration of renewable energy projects and science: Passive acoustic monitoring and marine mammals.\" Attendees reviewed a nested grid monitoring design for placing PAM detector broadly across whale habitat off the US east coast continental shelf and in areas of proposed wind energy development. The design is based on achieving 100% acoustic coverage of North Atlantic right whales by using 20 x 20 km grid cells spacing throughout offshore wind energy lease areas and larger 40 x 40 km grid cells aimed at connecting the offshore wind energy areas, with suggested PAM stations centered in each respective grid cell. The latter would achieve acoustic coverage of around 50% of the area monitored, balancing the costs and logistics of collecting regional data with the ability to detect species presence across contiguous areas of interest within and between offshore wind areas. More detailed regional PAM monitoring designs can be seen for the five main current wind energy areas of interest. Baseline monitoring over the larger region is essential in order to be able to understand changes in species presence at a relevant scale for these highly migratory baleen whale species. The area grids will be updated as new wind energy areas are leased.\n
