<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Coastal restoration, beach nourishment, and habitat reconstruction are crucial to mitigate future coastal erosion, land loss, flooding, and storm damage along the US Atlantic coast. The success of long-term coastal resilience efforts partially depends on locating and securing significant quantities of OCS sediment resources that are compatible with the target environments being restored. Offshore sand resources, like upland sources, are extremely scarce where most needed. Additionally, some areas of these relatively small offshore sand resources are not extractable because of the presence of infrastructure or sensitive areas (e.g. archaeological sites, protected habitat, etc.). Since the use of OCS sediment resources is authorized by the BOEM through its Marine Minerals Program, the bureau is implementing measures to help safeguard the most significant OCS sediment resources, reduce multiple use conflicts, minimize interference with existing leases (e.g. renewable energy) and rights-of-way (e.g. submerged infrastructure, shipping lanes, military operations, etc.), and help avoid sensitive areas (e.g. archaeological sites, protected habitat, etc.). The Atlantic Sand Aliquots dataset contains Outer Continental Shelf (OCS) block aliquots (1/16th of OCS protraction grid block) in the BOEM Atlantic Ocean Region that lie at least partially within a 1 statute mile buffer of where OCS sand resources have been identified through reconnaissance and/or design-level studies (see MMIS Sand Resources layer). During the planning process, entities may reference the aliquot attributes provided in this dataset to inquire about specific resources within those areas. In doing so, the BOEM MMP can continue to serve as an effective steward of our OCS resources. This dataset will be updated as new information about OCS sand resources is incorporated into the Marine Minerals Information System (MMIS).</SPAN></P></DIV></DIV></DIV>
The Atlantic OCS Aliquots with Sand Resources layer serves as a planning tool to assist in the management of Outer Continental Shelf (OCS) sediment resources, reduce multiple use conflicts, minimize interference with existing leases (e.g. renewable energy) and rights-of-way (e.g. submerged infrastructure, shipping lanes, military operations, etc.), and help avoid sensitive areas (e.g. archaeological sites, protected habitat). Each Atlantic Sand Aliquot block lies at least partially within a 1 statute mile buffer of where sand resources have been identified through reconnaissance and/or design-level OCS studies (see MMIS Sand Resources layer). Additional OCS studies may be necessary in order to refine and quantify the extents of sand resources within these areas. The Marine Minerals Program (MMP) within the Bureau of Ocean Energy Management (BOEM) is responsible for managing non-energy minerals (primarily sand and gravel) on the OCS. Access to and identification of potential OCS sand resources is critical for the long-term success and cost-effectiveness of many shore protection, beach nourishment, and coastal habitat restoration projects along the Gulf of Mexico and Atlantic Ocean coasts. By replenishing these areas with sand from the OCS, the Nation's coastlines receive crucial resources for the maintenance of a healthy coastal ecosystem. This dataset will be updated as new information about OCS sand resources is incorporated into the Marine Minerals Information System (MMIS).

Conceptual consistency: adherence to rules of the conceptual schema
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 MMPGIS 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.

Completeness omission: data absent from the dataset, as described by the scope
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 MMPGIS data model are collections of data from multiple sources and across multiple dates. Most likely, these MMPGIS 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.
