Abstract

The overall aim of the project is to provide the Regional Wildlife Science Collaborative for Offshore Wind (RWSC) Marine Mammal Subcommittee with analyses and recommendations to support the optimal design of a baleen whale passive acoustic monitoring (PAM) network along the U.S. East Coast. A recommended regional PAM monitoring design for the Northeast U.S. offshore wind energy areas (WEAs) was provided by Van Parijs et al. (2021) (see Figure SI-2 in that paper, referred to here as the “Van Parijs et al. design” ). The design is based on a network of PAM stations at two spatial resolutions: a 20 x 20 km grid around the WEAs (referred to here as the “small PAM grid”), and a 40 x 40 km grid between the WEAs (referred to as “large PAM grid”). Each PAM station comprises a single hydrophone bottom-mounted archival recorder. Here the study present results, based on computer simulation, of the statistical power of this proposed design to detect biologically realistic changes in simulated whale distribution and behavior associated with construction and operation of wind farms within the WEAs. Additionally the report evaluates two alternative designs for each WEA: (1) a 10 x 10 km small PAM grid, and (2) a linear array of PAM stations in a T-configuration (i.e., with three “arms”) centered on each development area (“T-design”).
