Seabird Bycatch Reduction in Northeast U.S. and Atlantic Canada Fisheries

This project will reduce incidental mortality of great shearwaters, northern gannets, and other seabirds injured by the Deepwater Horizon oil spill by testing seabird bycatch reduction strategies. The oil spill had a large impact on northern gannets and great shearwaters. These seabirds use the offshore waters of the northern U.S. Atlantic coastline for feeding and resting during their nesting season and migration.

Deep-Sea Benefits - Outcomes of Mesophotic and Deep Benthic Community Restoration

This project will collect and analyze data to directly assess benefits to Fish and Water Column Invertebrates, Marine Mammals, and Sea Turtles associated with Mesophotic and Deep Benthic Community restoration conducted in the Open Ocean restoration area. This project will collect three years of new data to quantify connections between Marine Mammal, Sea Turtle, Fish and Water Column Invertebrate and Mesophotic and Deep Benthic Community habitats by monitoring species distributions, abundances, habitat use, community composition, and trophic dynamics at select locations in the Gulf.

Evaluation Framework for Marine Mammal and Sea Turtle Restoration

The project will develop a feasible and cost-effective framework to evaluate the cumulative outcomes of Deepwater Horizon (DWH) Natural Resources Damage Assessment (NRDA) restoration projects for marine mammals and sea turtles in the Open Ocean Restoration Area. This will be done using a Structured Decision Making (SDM) process that incorporates expert elicitation techniques to quantify the benefits of Open Ocean restoration actions.

Analysis of Open Ocean Habitat Use, Threats, and Animal Movements

This activity will synthesize available information on priority habitats, habitat use, and movement of Open Ocean resources (Gulf sturgeon, mesophotic and deep benthic communities, and focal species representing marine mammals, sea turtles, birds, fish, and water column invertebrates) and threats affecting these resources. Examination of the overlap between threats and resources will help identify locations where threat reduction projects may have greater impact, and serve as a baseline against which the Trustee Implementation Group's threat reduction work may be evaluated.

Gulf-wide Status of Nesting Sea Turtles and Beaches Data Inventory

This activity will identify knowledge gaps in information needed to understand the status of sea turtles at three life-history stages across the Gulf of America: adult nesting females, incubating eggs, and hatchlings. The information will be used to identify restoration needs and assess progress in restoring sea turtles injured by the Deepwater Horizon oil spill.

Characterization of Caribbean Fisheries Interactions with Highly Migratory Species

The project will compile fishing data from Caribbean resource agencies, put this data in an accessible format, and conduct analysis to support restoration planning. Priority species for this project are blue marlin and yellowfin tuna, with secondary benefits to dolphinfish and other living marine resources. The analysis will include an assessment of the existing data collection programs and identify limitations that might represent challenges for restoration planning.

Conceptual Model to Inform Open Ocean Ecosystem Indicators

This activity will develop a conceptual model (CM) that will help organize what is known and not known about how restoration activities implemented by the Open Ocean Trustee Implementation Group (OO TIG) affect the resources and habitats that are the focus of OO TIG restoration (i.e., fish and water column invertebrates, marine mammals, birds, mesophotic & deep benthic communities, and sea turtles).
