Description

These data were acquired by BOEM (formerly MMS and USGS). Under the terms of procurement, these data are to be available to the public 25 years after the issuance of the exploration permit.

Purpose

These data were acquired commercially for geophysical and geological (G&G) exploration of oil and gas prospects on the U.S. Outer Continental Shelf (OCS). The Dept. of Interior, which regulates G&G activities on the OCS, acquired these data in order to ensure that the Federal government received fair market value for leases issued for oil and gas production on the OCS, and to accomplish other regulatory functions.

Notes

MCS Data transferred from BOEM to USGS for posting on NAMSS. Limited information available.

Other Survey Identifiers

M77-008 was used by Bureau of Ocean Energy Management.
