This Map Service contains many of the primary data types created by both the Bureau of Ocean Energy Management (BOEM) and the Bureau of Safety and Environmental Enforcement (BSEE) within the Department of Interior (DOI) for the purpose of managing offshore federal real estate leases for oil, gas, minerals, renewable energy, sand and gravel. These data layers are being made available as REST mapping services for the purpose of web viewing and map overlay viewing in GIS systems. Due to re-projection issues which occur when converting multiple UTM zone data to a single national or regional projected space, and line type changes that occur when converting from UTM to geographic projections, these data layers should not be used for official or legal purposes. Only the original data found within BOEM/BSEE’s official internal database, federal register notices or official paper or pdf map products may be considered as the official information or mapping products used by BOEM or BSEE. A variety of data layers are represented within this REST service are described further below. These and other cadastre information the BOEM and BSEE produces are generated in accordance with 30 Code of Federal Regulations (CFR) 256.8 to support Federal land ownership and mineral resource management.

Currently the following layers are available from this REST location:
OCS Drilling Platforms
-Locations of structures at and beneath the water surface used for the purpose of exploration and resource extraction. Only platforms in federal Outer Continental Shelf (OCS) waters are included. A database of platforms and rigs is maintained by BSEE.
OCS Oil and Natural Gas Wells
-Existing wells drilled for exploration or extraction of oil and/or gas products. Additional information includes the lease number, well name, spud date, the well class, surface area/block number, and statistics on well status summary. Only wells found in federal Outer Continental Shelf (OCS) waters are included. Wells information is updated daily. Additional files are available on well completions and well tests. A database of wells is maintained by BSEE.
OCS Oil & Gas Pipelines
-This dataset is a compilation of available oil and gas pipeline data and is maintained by BSEE. Pipelines are used to transport and monitor oil and/or gas from wells within the outer continental shelf (OCS) to resource collection locations. Currently, pipelines managed by BSEE are found in Gulf of Mexico and southern California waters.
Proposed Centerline for the Atlantic Wind Connect Project
- The Atlantic Wind Connection (AWC) Project is the first offshore backbone electrical transmission system proposed in the United States. This high-voltage direct-current, subsea backbone transmission system would be constructed off the coasts of New York, New Jersey, Delaware, Maryland, and Virginia.
Unofficial State Lateral Boundaries
- The approximate location of the boundary between two states seaward of the coastline and terminating at the Submerged Lands Act Boundary. Because most State boundary locations have not been officially described beyond the coast, are disputed between states or in some cases the coastal land boundary description is not available, these lines serve as an approximation that was used to determine a starting point for creation of BOEM’s OCS Administrative Boundaries. GIS files are not available for this layer due to its unofficial status.
BOEM OCS Administrative Boundaries
- Outer Continental Shelf (OCS) Administrative Boundaries Extending from the Submerged Lands Act Boundary seaward to the Limit of the United States OCS (The U.S. 200 nautical mile Limit, or other marine boundary)For additional details please see the January 3, 2006 Federal Register Notice.
BOEM Unofficial OCS Boundaries
- Unofficial Outer Continental Shelf Boundaries: Due to a discontinuity off the SW coast of Florida, South of 26° N, a layer was created to provide a complete Fed-State Line. Currently this proposed Fed-State line is awaiting approval.
BOEM Limit of OCSLA ‘8(g)’ zone
- The Outer Continental Shelf Lands Act '8(g) Zone' lies between the Submerged Lands Act (SLA) boundary line and a line projected 3 nautical miles seaward of the SLA boundary line. Within this zone, oil and gas revenues are shared with the coastal state(s). The official version of the ‘8(g)’ Boundaries can only be found on the BOEM Official Protraction Diagrams (OPDs) or Supplemental Official Protraction described below.
Submerged Lands Act Boundary
- The SLA boundary defines the seaward limit of a state's submerged lands and the landward boundary of federally managed OCS lands. The official version of the SLA Boundaries can only be found on the BOEM Official Protraction Diagrams (OPDs) or Supplemental Official Protraction Diagrams described below.
Atlantic Wildlife Survey Tracklines(2005-2012)
- These data depict tracklines of wildlife surveys conducted in the Mid-Atlantic region since 2005. The tracklines are comprised of aerial and shipboard surveys. These data are intended to be used as a working compendium to inform the diverse number of groups that conduct surveys in the Mid-Atlantic region.The tracklines as depicted in this dataset have been derived from source tracklines and transects. The tracklines have been simplified (modified from their original form) due to the large size of the Mid-Atlantic region and the limited ability to map all areas simultaneously.The tracklines are to be used as a general reference and should not be considered definitive or authoritative. This data can be downloaded from http://www.boem.gov/uploadedFiles/BOEM/Renewable_Energy_Program/Mapping_and_Data/ATL_WILDLIFE_SURVEYS.zip
BOEM OCS Protraction Diagrams & Leasing Maps
- This data set contains a national scale spatial footprint of the outer boundaries of the Bureau of Ocean Energy Management’s (BOEM’s) Official Protraction Diagrams (OPDs) and Leasing Maps (LMs). It is updated as needed. OPDs and LMs are mapping products produced and used by the BOEM to delimit areas available for potential offshore mineral leases, determine the State/Federal offshore boundaries, and determine the limits of revenue sharing and other boundaries to be considered for leasing offshore waters. This dataset shows only the outline of the maps that are available from BOEM.Only the most recently published paper or pdf versions of the OPDs or LMs should be used for official or legal purposes. The pdf maps can be found by going to the following link and selecting the appropriate region of interest.
Both OPDs and LMs are further subdivided into individual Outer Continental Shelf(OCS) blocks which are available as a separate layer. Some OCS blocks that also contain other boundary information are known as Supplemental Official Block Diagrams (SOBDs.) Further information on the historic development of OPD's can be found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf: http://www.boemre.gov/itd/pubs/1999/99-0006.PDF
Also see the metadata for each of the individual GIS data layers available for download. The Official Protraction Diagrams (OPDs) and Supplemental Official Block Diagrams (SOBDs), serve as the legal definition for BOEM offshore boundary coordinates and area descriptions.
BOEM OCS Lease Blocks
- Outer Continental Shelf (OCS) lease blocks serve as the legal definition for BOEM offshore boundary coordinates used to define small geographic areas within an Official Protraction Diagram (OPD) for leasing and administrative purposes. OCS blocks relate back to individual Official Protraction Diagrams and are not uniquely numbered. Only the most recently published paper or pdf versions of the OPDs or LMs or SOBDs should be used for official or legal purposes. The pdf maps can be found by going to the following link and selecting the appropriate region of interest within the OPD/SOBD table.http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Index.aspx
BOEM Block Aliquots
- Aliquots are generated from full Outer Continental Shelf (OCS) blocks by sub-dividing each block into 16ths and allow for more detailed boundary delineation in offshore energy leasing. The aliquots use a letter designation in addition to their parent protraction number and OCS block number (ie. NK-1802, 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 Fed/State OCS boundary and along UTM zone borders. This dataset includes aliquots for 60 protractions out of the available 80 protractions in the Atlantic and 36 of 71 off the US West Coast . The remaining 56 protractions are located on the seaward edge of the OCS . Aliquots for these protractions will be produced at a later date as needed.
BOEM Renewable Energy Leases
- Blocks that are currently leased from the federal government by industry for the purpose of development of wind or other renewable energy or for research and monitoring purposes.
Federal OCS Sand and Gravel Borrow (Lease Areas)
– Federal outer Continental Shelf (OCS) Sand and Gravel Borrow Areas (Lease Areas) are polygons which are maintained by the Bureau of Ocean Energy Management (BOEM), part of the U.S. Department of the Interior. The polygons define areas where entities that have entered into a Negotiated Non-Competitive Lease or Memorandum of Agreement with BOEM can dredge sand, gravel or shell resources from the OCS. Section 8 (k) of the OCS Lands Act (OCSLA), as amended by Public Law 103-426 (enacted in 1994), provides BOEM the authority to negotiate an agreement for the use of OCS sand, gravel, and shell resources for use in: (1) a project for shore protection, beach restoration, or coastal restoration under taken by a Federal, State, or local government agency; or (2) for use in a construction project funded in whole or in part by, or authorized by, the Federal government. This dataset is a collection of previous and current authorized lease areas under BOEM's purview. The intent is to update the dataset when leases are added or renewed. Attribution consists of state, sand volume, and dates and identification properties associated with the lease. Revisions to the data, which would most often be to attribution, will occur regularly.
BOEM Oil and Gas Leases
– Blocks that are currently leased from the federal government by industry for the purpose of development of traditional oil or gas energy products and may or may not be actively developed or producing. Leases in state waters are not included in this layer.
BOEM Wind Planning Areas
-This data set represents the most recent changes for the Wind Development Planning Areas in the Atlantic. Wind Planning Areas in this dataset represent up to seven different types of announcements within the US Federal Register that can be used to show the current status of an area that is being considered for Wind Power Development. The Original February 2011 Smart from the Start Wind Energy Areas (WEAs) are represented in a separate layer. Not all areas will start out as WEAs. For the areas represented here, once an area has changed from one type of area to another, it will be replaced entirely by the new area. In many cases the area may be more than one type of area at the same time. The Category or Info attribute will show the reader which type of category the area is. The types of areas and their descriptions can be found in the Attributes section of the metadata record.
Wind Energy Areas February 2011
- WEAs are offshore locations that appear most suitable for wind energy development. Secretary Salazar identified the WEAs on February 7, 2011 in a joint announcement with Secretary Chu of the U.S. Department of Energy as part of the National Strategic Work Plan for Offshore Wind. Data has been andwill continue to be collected for these high priority areas to inform government and industry assessments and planning, allowing a more efficient process for permitting and siting responsible development. Requests for Interest (RFIs) and Calls for Information have been or will be issued for these new WEAs to support lease sale environmental assessments. This file can be downloaded from http://www.boem.gov/Renewable-Energy-Program/Smart-from-the-Start/Index.aspx
Atlantic Wildlife Survey Study Areas (2005-2012)
- These data depict study areas (footprints) of wildlife surveys conducted in the Mid-Atlantic region since 2005. The study areas are comprised of aerial and shipboard surveys. These data are intended to be used as a working compendium to inform the diverse number of groups that conduct surveys in the Mid-Atlantic region. The study areas as depicted in this dataset have been derived from source tracklines and transects. The areas have been simplified due to the large size of the Mid-Atlantic region and the limited ability to map all areas simultaneously. The areas are to be used as a general reference and should not be considered definitive or authoritative. This data can be downloaded fromhttp://www.boem.gov/uploadedFiles/BOEM/Renewable_Energy_Program/Mapping_and_Data/ATL_WILDLIFE_SURVEYS.zip
Proposed Final OCS Oil and Gas Leasing Program 2012-2017
-Management of the oil and gas resources of the Outer Continental Shelf (OCS) is governed by the OCS Lands Act (Act), which sets forth procedures for leasing, exploration, and development and production of those resources. Section 18 of the Act calls for the preparation of an oil and gas leasing program indicating a five year schedule of lease sales designed to best meet the Nation’s energy needs. The Bureau of Ocean Energy Management (BOEM) is the bureau within the Department of the Interior (DOI) that is responsible for implementing these requirements of the Act related to preparing the leasing program. BOEM is in the process of preparing a Five Year Program for 2012-2017. This data is from the Proposed Final Program (PFP), which is the third in a series of mandated leasing proposals developed for public review before the Secretary of the Interior may take final action to approve the new Five Year Program for 2012-2017. This dataset will be replaced with the Final Five Year Program layers once they have been approved.
BOEM Oil and Gas Planning Areas
- Planning areas are used to support the 5-Year Oil and Gas Program consisting of a schedule of oil and gas lease sales indicating the size, timing and location of proposed leasing activity the Secretary of Interior determines will best meet national energy needs for the five year period following its approval. An area must be included in the current 5-Year Program in order to be offered for leasing. Section 18 of the OCS Lands Act prescribes the major steps involved in developing a 5-Year Program including extensive public comment steps. A 5-Year Program balances energy needs and environmental considerations in accordance with 30 Code of Federal Regulations (CFR) 256.8 to support Federal land ownership and mineral resource management.
Outer Continental Shelf Lands Act
– The spatial footprint that shows the approximate location of the authority granted to the federal government under the Outer Continental Shelf Lands Act as amended.
2010 Vessel Traffic (AIS)
-Derived from 2010 Automatic Identification System (AIS) broadcast returns. Each vessel count per aliquot represents the number of vessels traveling through the block during the year of 2010. An aliquot measures 1/16 of a full OCS leasing block or 1200 x 1200 meters. Only areas where BOEM publishes Official Protraction Diagrams will contain the aliquot AIS counts, therefore, large areas of inland state waters may be missing aliquot AIS counts. The data has also been clipped so that any aliquot that touches land has been deleted so that the user can discern the location of the coastline. Vessel type breakdowns can be viewed using the ID tool or by downloading the data.
2009 Vessel Traffic (AIS)
-Derived from 2009 Automatic Identification System (AIS) broadcast returns. Each count per aliquot block represents the number of vessels traveling through the block during the year of 2009. An aliquot measures 1/16 of a full OCS leasing block or 1200 x 1200 meters. The original raw data for June 2009 is missing 25 days of broadcast data.
230,000 sq km of seismic data interpretation mapping over 28,000 seafloor seismic amplitude anomalies in the Gulf of Mexico using 3-D time-migrated seismic surveys. This mapping program means to understand the distribution of natural hydrocarbon seeps and the related benthic fauna, and to characterize other seafloor features related to the geological framework of the seafloor. These areas show anomalously high or low amplitude response over the background response, and include: Positive- Slow to moderate hydrocarbon seepage Negative- Rapid expulsion of sediment, brine, and hydrocarbons Mud volcano- Cones created by negative anomalies Confirmed mud volcano- Direct observation of mud volcanos Flow- Sediment flows from fast moving sediment or hydrocarbons Pockmark- Circular to oval depressions created by the rapid removal of sediment Cretaceous- Outcrops of Cretaceous-aged carbonate rock Lithologic- Outcrops of Cretaceous-aged carbonate rock Salt- Salt outcrops (not seep related) Slump- Downslope sediment flows Fan- Submarine channels and sand rich turbidite fans Confirmed organisms- Direct observation of chemosynthetic and coral communities Confirmed coral- Direct observation of benthic corals Confirmed gas hydrate- Direct observation of gas hydrate occurrences Confirmed gas- Direct observation of gas plumes Confirmed oil- Direct observation of oil seepage Possible oil positive- high positive oil seepage located under an oil slick Possible oil negative- low positive oil seepage located under an oil slick For more detailed information, and individual layers for download: http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Map-Gallery/Seismic-Water-Bottom-Anomalies-Map-Gallery.aspx
BOEM Marine Hydrokinetic Planning Areas
-This data set represents the most recent changes for the Marine Hydrokinetic (MHK) Development Planning Areas in the Outer Continental Shelf. MHK Planning Areas in this dataset represent up to six different types of announcements within the US Federal Register that can be used to show the current status of an area that is being considered for wave, current, or tidal power development. Previous MHK Planning Areas that are now designated as leases can be found on the BOEM Renewable Energy Leases Shapefile. See attribute table for links to more information about each area.
OCS - Oil and Gas Resource Plays
This data layer shows the extent of the probable oil and/or gas geologic structures (plays) identified within the US Outer Continental Shelf. Plays are groups of known and/or postulated sub-seafloor pools (hydrocarbon accumulations) that share common geologic, geographic, and temporal properties, such as history of hydrocarbon generation, migration, reservoir development, and entrapment. Geologic classifications of each play and its potential are described in the associated reports for each region. The analysis was based on seismic surveys analyzed by BOEM geologists. The layer is classified according to the number of plays thought to be present within the area represented. Plays are represented in horizontal space but may overlap vertically allowing for multiple plays in the same horizontal space. Individual region files can be downloaded from the following location: http://www.boem.gov/National-Assessment-Shape-Files/
Marine Minerals Significant Sand Resource Blocks
- This data set contains OCS block outlines and delineated polygons in ESRI ArcGIS shape file format for the BOEM Gulf of Mexico Region that contain sediment resources and areas of disposal in support of the Marine Minerals Program. Coastal restoration, beach nourishment, and levee reconstruction are crucial to mitigate future coastal erosion, land loss, flooding, and storm damage in the Gulf of Mexico. The success of that long-term effort 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, vast areas of these relatively small offshore sand resources are not extractable because of the presence of oil and gas infrastructure, archaeologically sensitive areas, and biologically sensitive areas. Since the use of OCS sediment resources is authorized by the BOEM through its Marine Mineral Program, the bureau is implementing several measures to help safeguard the most significant OCS sediment resources, reduce multiple use conflicts, and minimize interference with oil and gas operations under existing leases or rights-of-way.
