The study was conducted in an effort to collect data needed to assess potential impacts of development of the NYLA on environmental and socioeconomic concerns (BOEM 2014b). Specifically, the objectives of this project were to: (1) establish an acoustic telemetry array in the lease area and a nearshore connector array, (2) tag 100 Atlantic sturgeon and 118 individuals of other species, (3) estimate the total number and proportion of tagged individuals present in the NYLA and (4) estimate occurrence as
