Title:
American Samoa Request for Information and Interest Blocks and Aliquots
Geospatial_Data_Presentation_Form: vector digital data

Abstract:
BOEM conducted an evaluation of an unsolicited request to lease Outer Continental Shelf (OCS) minerals in an area offshore American Samoa. This Request for Information and Interest (RFI) requests information and comments on and indications of interest in the leasing of OCS minerals in and around the RFI Area. BOEM will consider information and interest received in response to this RFI when considering whether to proceed with additional steps leading to the offer of OCS mineral lease(s) on the OCS offshore American Samoa. Those interested in providing comments or information should provide the information requested in section 5, “Types of Information and Comments Requested,” of this RFI. Those interested in leasing in and around the RFI Area for OCS mineral development should provide the information described in section 6, “Requested Information for Indications of Interest.” BOEM may or may not offer a lease for commercial OCS mineral development offshore American Samoa after further consultations, public participation, and environmental analyses. For more information please visit https://www.boem.gov/marine-minerals/discovering-offshore-critical-mineral-resources-pacific-outer-continental-shelf. This area represents all blocks and aliquots of the RFI area. What are aliquots?Aliquots are generated from Outer Continental Shelf (OCS) blocks by subdividing each block into 16ths, and this further subdivision allows for more detailed boundary delineation in offshore energy leasing. These polygons are clipped to the Submerged Land Act Boundary and Continental Shelf Boundaries. The aliquots use a letter designation in addition to their parent protraction number and OCS block number (e.g., NK18-02, 6822F). A full OCS block is 4800 x 4800 meters, while an aliquot measures 1200 x 1200 meters. Smaller, clipped aliquots are found along the Federal/State OCS boundary and along UTM zone borders. Only the most recently published paper or PDF versions of the Official Protraction Aliquot Diagram (OPAD) should be used for official or legal purposes. These data were created in the applicable NAD83 UTM or NAD27 UTM/SPCS Projection and re-projected to GCS WGS84 (EPSG 4326) for management in BOEM's enterprise GIS. Because GIS projection and topology functions can change or generalize coordinates, these data are NOT an OFFICIAL record for the exact boundaries. These data are to be used for cartographic purposes only and should not be used to calculate area.
Purpose:
All blocks and aliquots of the American Samoa Request for Interest (RFI.)
