Abstract
Federal government mapping of the offshore areas of the USA in support of the development of oil and gas resources began in 1954. The first mapping system utilized a network of rectangular blocks defined by State Plane coordinates which was later revised to utilize the Universal Transverse Mercator grid. Creation of marine boundaries directed by the Submerged Lands Act and Outer Continental Shelf Lands Act were mathematically determined using early computer programs that performed the necessary computations, but required many steps. The Bureau of Ocean Energy Management is revising these antiquated methods using Geographic Information System technology which will provide the required accuracy and produce the mapping products needed for leasing of energy resources, including renewable energy projects, on the outer continental shelf.
Highlights
The Bureau of Ocean Energy Management, formerly the Minerals Management Service, is the bureau within the U.S Department of the Interior that is responsible for the exploration and development of energy and marine mineral re-sources on the Outer Continental Shelf of the United States
While diagrams illustrating where the Submerged Lands Act boundary passed through an Outer Continental Shelf block had been created as early as 1957, the format for the Supplemental Official Block Diagram was not developed until 1980
Supplemental Official Block Diagrams are generated for all Outer Continental Shelf blocks which contain a portion of a boundary, such as the Submerged Lands Act boundary
Summary
The Bureau of Ocean Energy Management, formerly the Minerals Management Service, is the bureau within the U.S Department of the Interior that is responsible for the exploration and development of energy and marine mineral re-sources on the Outer Continental Shelf of the United States This includes the leasing of the mineral resources of the seabed of the Outer Continental Shelf. The marine cadastre includes the block grids and official boundaries, which provide the base for most of the Bureau of Ocean Energy Management offshore maps and leasing processes. It gives the Bureau of Ocean Energy Management the means to define, describe, analyze, and account for every acre/hectare of federal offshore submerged lands
