Item Identification

Title: Marine Mammal Protection Act
Status: Completed
Publication Date: 2016-05-11

The Marine Mammal Protection Act (MMPA or Act) prohibits, with certain exceptions, the "take" of marine mammals in U.S. waters and by U.S. citizens on the high seas, and the importation of marine mammals and marine mammal products into the U.S. The MMPA gives the Secretary of Commerce, working through the National Oceanic and Atmospheric Administration's National Marine Fisheries Service, authority and duties under the Act for all Cetaceans (whales, dolphins, and porpoises) and Pinnipeds (seals and sea lions, except walruses), and gives authority for other species of marine mammals to the Secretary of the Interior, working through the U.S. Fish & Wildlife Service. The Secretaries are also required to prepare and periodically revise stock assessments of marine mammal stocks (section 117). In addition, the Secretary of Commerce must publish in the Federal Register and revise at least annually a list of commercial fisheries that categorizes the fisheries based on the incidence of serious injury and mortality of marine mammals (section 118(c)).


Date enacted: October 21, 1972

Codification: 16 U.S.C. Sec. 1361 et seq.

Authority: National Oceanic and Atmospheric Administration and U.S. Fish & Wildlife Service


To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Data Quality


The attributes in this dataset are believed to be accurate.

Horizontal Positional Accuracy:

Maximum scale of intended use is 1:80,000.

Completeness Report:

Spatial and attribute properties are believed to be complete. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.

Conceptual Consistency:

Topology has been validated, including least possible modification of the original data as needed to correct topology errors. These errors were noted in southern Alaska (two errors) and the Gulf of Mexico (two errors).

Process Steps

Process Step 1

CC ID: 652838

1. The Marine Mammal Protection Act's geographic coverage was developed from two existing data sets: (A) OCS's U.S. Maritime Limits and Boundaries shapefile (EEZ and equivalent boundary), and (B) USGS's US/Mexico international boundary. 2. Where boundaries from the two data sources intersected in Texas and California, boundaries were cut accordingly so that no ArcGIS "dangles" remained. 3. Where boundaries in the Pacific Ocean crossed the International Date Line, the single part polylines were manually closed within an edit session. 4. Topology errors were addressed, which included two errors in southern Alaska and two errors in the Gulf of Mexico (within the OCS data). 5. The national polyline (including Alaska, Hawaii, and all U.S. territories) was converted to a polygon. 6. Added fields and populated accordingly.
