The objectives of this project are to 1) collect high resolution multibeam and fisheries acoustic data in depths approximately 10 to 1000 meters so as to continue to characterize seafloor habitats and fish biomass hotpots in priority areas in the SE US Atlantic Waters (Outer Continental Shelf) including hardbottom seafloor habitats, sand shoals and ridges, and Ocean Dredge Material Disposal Sites (ODMDS, US Environmental Protection Agency), 2) validate seafloor habitat types using drop cameras from small boats, and 3) conduct ecological assessments of ODMDS and adjacent hardbottom habitats to determine habitat value. In addition, this project will include piggy-back objective: 1) evaluate a new unmanned surface vehicle (USV) for use in extending capabilities for seafloor mapping by NOAA survey, researchers and partners.

Cruise NF-12-05-SBNMS (Stellwagen Bank National Marine Sanctuary) (EK60). The project will place synchronous motion, acoustic recording tags on humpback and fin whales, while concurrently measuring prey field size, shape and composition. The goal is to understand water column use by endangered whales and how prey patch characteristics influence whale behavior as a way to recommend mitigation measures related to collisions between endangere d whales and commercial ships and/or fishing gear. Additionally, whale acoustic data collected will allow us to evaluate the efficacy of passive acoustic monitoring for these species by age and reproductive class.

The mission of the Office of National Marine Sanctuaries (ONMS) is to conserve, protect, and enhance the biodiversity, ecological integrity, and cultural legacy of specially designated marine protected areas around the world. NOAA has recently given clearance to begin scoping meetings to explore expansion of the Monitor National Marine Sanctuary (MNMS). This project will allow MNMS to inventory and assess resources in the proposed new expansion areas. Data collected in these new areas and within the existing sanctuary is critical to expansion and the completion of the MNMS Condition Report. This project also furthers ONMS and NCCOS goals by providing critical data to support our understanding of essential fish habitat on both naturally occurring and anthropomorphic bottom features on the continental shelf off the mid-Atlantic coast. This project employs new advances in underwater acoustic seafloor mapping technologies that will not only assess the biota of live bottom habitats but also submerged cultural resources such as shipwrecks, that have become essential fish habitats in their current role as artificial reefs. Acoustic survey methods, along with multi-beam mapping provide an efficient method on producing information on fish distribution, areas of high productivity, seafloor features, and cultural resources.
