<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Outer Continental Shelf (OCS) Study Area polygons represent the generalized geographic extent of studies that have contributed to the stewardship goals of the Bureau of Ocean Energy Management's (BOEM) Marine Minerals Program (MMP). These studies were fully or partially funded by the Bureau of Ocean Energy Management and or partner agencies and consist of reconnaissance- and design-level sand and gravel resource assessments, geologic and geophysical framework studies, research on baseline benthic ecological conditions, and studies aimed at understanding the potential effects of dredging operations on the physical, chemical, and biological environments. One of the main objectives of the MMP is to use these studies to help assess the effects of OCS activities on natural, historical, and human resources, and determine appropriate monitoring and mitigation techniques.

The MMIS data model utilizes a hierarchical structure where an ESRI enterprise geodatabase represents the top tier, and feature datasets and raster catalogs are the secondary tiers which contain groupings of similar data layers. These individual data layers were identified by MMP as important, and they make up the bottom tier. Most individual vector layers and tables are collections of data from multiple sources and across multiple dates. Extensive research went into the construction of (1) the hierarchical groupings of data (primarily by subject matter and file format) and (2) technical aspects of the data model. Data within the geodatabase was consolidated to reduce redundancy, resulting in several stand-alone tables. Relationship classes utilizing global IDs were built between vector layers and stand-alone tables in order to link disparate data. The entire MMIS data model was originally constructed using ESRI ArcGIS Diagrammer, a tool that creates and edits a geodatabase schema. The resulting geodatabase structure, data, and relationship classes were reviewed thoroughly by multiple individuals using ESRI Geodatabase Diagrammer Add-In, ESRI ArcGIS, and Microsoft Visio. ESRI Geodatabase Diagrammer Add-In creates a detailed break-down of the geodatabase and a Visio data model poster.
The spatial data and attribute tables loaded into the MMIS data model are believed to be complete, in regards to maintaining each data layer/table after retrieving it from its source. Please refer to the scientific reports, as well as BOEM MMP Leases, negotiated agreements, Memoranda of Agreements, and project completion reports, for discussions of the results on the corresponding source data. Most individual vector layers and tables in the MMIS data model are collections of data from multiple sources and across multiple dates. Most likely, these MMIS layers/tables will continue to have more data loaded in the future, therefore expanding upon the list of sources and dates. Additionally, the Pacific Outer Continental Shelf (OCS) and Alaska OCS regions may eventually be added to the data model, aside from the Atlantic and Gulf of Mexico OCS regions.
Please refer to the scientific reports, as well as Bureau of Ocean Energy Management (BOEM) Marine Minerals Program (MMP) Leases, negotiated agreements, cooperative agreements, Memoranda of Agreements, and project completion reports, for accuracy statements on the corresponding source data. These documents are referenced in the attribute tables, where appropriate. In regards to attribute assignment in the Marine Minerals Information Systems (MMIS) data model, every effort was made to load source data into MMIS without error or modification. Some attributes contain domain restrictions in an effort to standardize the field entries and to decrease potential inconsistent entries (e.g., spelling, grammar, typographical errors, and subject matter) in the attribute.

The spatial and tabular data presented in this dataset were identified by the Bureau of Ocean Energy Management (BOEM) Marine Minerals Program (MMP) for the MMIS project as being critical for MMP's decision making and management responsibilities of Federal Outer Continental Shelf (OCS) mineral exploration and Federal non-energy sand/gravel lease activities. The spatial extent of each study area in the OCS were either retrieved directly from BOEM in the form of ESRI's ArcGIS shapefiles or the polygons were manually digitized in ArcMap by referencing written descriptions and figures from the study report. A study area polygon feature was made for each study and loaded into a project-specific geodatabase in its native projection. Next, a master layer was created in the MMIS geodatabase data model to house all OCS study area polygons in a single feature class (reprojected into the NAD83 geodetic reference system). Attributes added to the feature class include the state, year the report was published, and OCS study area ID. Next, the disparate OCS study area feature classes and their attribute data were loaded into the MMIS OCS Study Areas feature class. For increased accessibility, each study area polygon was linked to the corresponding PDF report document(s) within the MMIS geodatabase.

Outer Continental Shelf (OCS) Study Area polygons represent the generalized geographic extent of studies that have contributed to the stewardship goals of the Bureau of Ocean Energy Management's (BOEM) Marine Minerals Program (MMP). These studies were fully or partially funded by BOEM, an agency within the U.S. Department of the Interior, and consist of reconnaissance- and design-level sand and gravel resource assessments, geologic and geophysical framework studies, research on baseline benthic ecological conditions, and studies aimed at understanding the potential effects of dredging operations on the physical, chemical, and biological environments. Data and conclusions from such studies are heavily relied upon by the Bureau of Ocean Energy Management (BOEM) Marine Minerals Program (MMP) when making decisions for how to best manage non-energy mineral resources (primarily sand and gravel) on the OCS. Informed decision-making by BOEM ensures that the removal of any mineral resource is conducted in a safe and environmentally sound manner, and that any potentially adverse impacts on the marine, coastal, or human environments are avoided or minimized. OCS study area polygons were either provided along with the report in spatial format, such as an ArcGIS shapefile, or were manually digitized by referencing written descriptions, figures, or the spatial extent of data collection and analysis.
