Point nesting data, Environmental Sensitivity Index (ESI) importance and nesting areas and sightings per unit effort (SPUE) for the three species of turtles - Green sea turtle, Leatherback turtle, and Loggerhead turtle.
Marine Mammal data: assessed, combined and converted from seasonal species sightings into 10-minute squares. Individual grids were then multiplied by 1000 and divided by seasonal effort grids previously generated by the U.S. Navy. The resulting sightings per unit effort (SPUE) grids were used to identify important areas within the Ecoregion for each species.
The three components of benthic data used for creation of the Ecological Marine Units (EMUs) and the Benthic Habitat Types (combinations of EMUs considered with their species assemblages) for the Northwest Atlantic Marine Ecoregional Assessment. Download includes: Bathymetry, Benthic Habitats, Benthic Sediment, Ecological Marine Units, Seabed Forms, and Ecoregional Boundaries.
Includes: Coastal Habitat, Coastal Marine Ecological Classification Standard (CMECS), Shoreline Units - represents a parsing tool to help compare and contrast geographies with the understanding that boundary changes, or splitting/lumping of areas may be desirable when developing conservation approaches at more localized geographies, Coastal Vulnerability Index (CVI) - provides insight into the relative potential of coastal change due to future sea-level rise, and Eelgrass.
Includes: Seasonal data on Zooplankton - biomass data were obtained from the COPEPOD database (NOAA) for 1977-2007, Chlorophyll - measured to determine phytoplankton concentration, Sea Surface Temperature - data were extracted from three dimensional climatologies representing 28 years from 1980 - 2007, averaged, and interpolated with ordinary kriging to produce a smooth surface, and Stratification - data helps describe the physical environment of the water column near the surface. These data help to understand the seasonal patterns of mixing and stratification that help to determine areas of high productivity and benthic-pelagic coupling.
Species richness of large pelagic fish - The richness of target species values were calculated to outline the diversity of the species in each ten minute square. The essential fish habitat (EFH) metrics were developed to understand how much of the region is considered EFH and to identify points were EFH for the target species overlapped. The persistence score identifies which target species were observed in the same ten minute square over time. The days fished metrics were calculated to understand the distribution of gillnet, longline, and bottom longline fishing trips.
Seasonal trends and weighted persistence for 3 target species: Blueback herring, American shad, and Atlantic mackerel The Trend in Abundance Metric was developed to address the following question concerning the distribution of specific fish species relative to places in the North Atlantic Marine Ecoregion: Where in the ecoregion has the abundance been increasing or decreasing? (trends) The Weighted Persistence metric was developed to address the following questions concerning the distribution of specific fish species relative to places in the North Atlantic Marine Ecoregion: Where in the ecoregion has the species been consistently found over time? (persistence) Where in the ecoregion is the species consistently...
Ecological Marine Units (EMUs) are the three-way combination of physical variables - depth, sediment grain size, and seabed forms. The breaks in bathymetry and substrate grain size are based on the ecological thresholds revealed by the benthic organism relationships. Download includes: Bathymetry, Benthic Habitats, Benthic Sediment, Ecological Marine Units, Seabed Forms, and Ecoregional Boundaries.
This data product was created as part of the Northwest Atlantic Marine Ecoregional Assessment. The Nature Conservancy developed this science-based ecoregional assessment for the Northwest Atlantic Marine region (Bay of Fundy to Cape Hatteras, North Carolina). This assessment synthesizes information on oceanography, chemistry, geology, biology, and social science to inform decisions about coastal and marine ecosystems. By integrating this information at a regional level, the Conservancy is able to provide both a greater understanding of the interrelated biological diversity of the marine ecoregion, and a clearer picture of the current condition of its natural areas and the challenges to their continued persistence....

This data product was created for the project titled: “Application of the Coastal and Marine Ecological Classification Standard (CMECS) to the Northwest Atlantic” which was partially funded by the U.S. Department of the Interior, Fish and Wildlife Service and a joint collaborative project with The Nature Conservancy (Eastern Division Conservation Science), University of Rhode Island (Graduate School of Oceanography), and Massachusetts Department of Fish and Game (Division of Marine Fisheries). In the Northeast United States region, efforts are underway to better organize and integrate spatial marine data to support ocean planning and management efforts. An important step in this process is translating existing...
