Abstract:
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. The ten categories of targets identified as the primary structure for the marine ecoregional assessment are: coastal and estuarine habitats, benthic habitats, diadromous fish, demersal fish, pelagic fish, forage fish, nearshore shellfish, shorebirds and seabirds, marine mammals, and sea turtles. For more information and a detailed report, please visit <http://nature.org/namera/>.
Seabed forms classify seafloor topography into discrete units. Derived from The Nature Conservancy's derived digital bathymetry, seabed forms can be described by a combination of just two variables: seabed position and slope. Seabed position (also referred to as topographic position or slope position) describes the topography of the area surrounding a particular cell. We based our seabed position calculations on Fels and Zobel's (1995) method, which evaluates the elevation differences between the model cell and the surrounding cells within a specified distance.
Purpose:
Seabed forms are one of the three componets of Ecological Marine Units (EMUs).

Access_Constraints:
The Nature Conservancy reserves all rights in data provided. All data are provided as is. This is not a survey quality dataset. TNC-derived data analysis cannot be relied on as a definitive statement of the presence or absence of individual species or significant ecological communities at given locations and cannot be substituted for ecological surveys that may be required for environmental assessment or conservation planning. The Nature Conservancy makes no warranty as to the currency, completeness, accuracy or utility of any specific data. This disclaimer applies both to individual use of the data and aggregate use with other data. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data.
Use_Constraints:
The Nature Conservancy (TNC) compiled this data set from publicly available data sources and this data is freely distributable without permission from this TNC resource office. This data set must be cited on all electronic and hard copy products using the language of the Data Set Credit. Use and analysis of the geographic data are limited by the scale at which the data was collected and mapped, and that, as a regional analysis, it is not intended for site level decisions.
