Cruise NF-12-04-SERA (Sanctuary Regional Development and Assessment) (EK60). 1)Ship based mapping and characterization of benthic habitats in the waters around Gray’s Reef National Marine Sanctuary. Collected data will need to include backscatter.2)Continuation of invertebrate recruitment investigation in Gray’s Reef. This project will include diving to assess the colonization and succession of invertebrates to a natural substrate. 3)Continue investigations to quantify variation in space and time of the abundance ofschooling prey and mid-water predators at mid-shelf reefs: this involves conducting survey lines using the EK-60 survey system. 4)Continue collecting data on the abundance,diversity and distribution of both fishes and invertebrates both in side and outside the proposed Research Area in Gray’s Reef.This will require divers to conduct visual fis hcensuses along transects and take pictures of quadrats to assess invertebrate fauna. 5)Gray’s Reef would like to explore the possibility of conducting night dives aboard its own diving vessels provided that this does not present theNancy Fostercrew with unduestaffing/overtime issues and would be worked out in advance of conducting operations.

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.
