Title: Defacto Marine Protected Areas of the United States
Short Name: Defacto_MPAs_2008
Status: Completed
Publication Date: 2008-06
Abstract:

These data provide the spatial boundaries of DeFacto Marine Protected Areas in U.S. Waters. With nearly 1200 sites (for which GIS data are available), DFMPAs cover 3% of the U.S. waters, (0-200 nautical miles offshore), which includes the Exclusive Economic Zone (EEZ), Territorial Sea, and state waters. DFMPAs range in size from less than one acre to more than 40,000 km2, though the vast majority is at the smaller end of this spectrum. Most of the small sites were created to provide places for vessels to anchor safely. Most of the large sites provide dedicated training and operation areas for various branches of the U.S. military, or facilitate the transfer of oil and gas to moored tanker vessels.

Purpose:

As a first step towards creating a national system, the National Marine Protected Areas Center (MPA Center) is synthesizing information on all existing place-based marine spatial management efforts in the country, including those that were not implemented specifically for conservation purposes. This report gives the first nation-wide view of the number, size, type, and purpose of DFMPAs in the United States. It answers the question, How many DFMPAs exist in the United States, and how are they currently being used?

Notes:

1505

Supplemental Information:

Marine areas that are set aside for reasons other than conservation, such as economic, human health or safety, and protection of government or private property are called de facto MPAs (DFMPAs). These are places where activities are restricted by law for reasons other than conservation or natural resource management. Familiar examples include: safety, security, and danger zones, restricted areas, prohibited lightering areas, some anchorage grounds, and traffic separation schemes.

Data Quality

Completeness Report:

The inventory is complete as of June 2008.

Conceptual Consistency:

Inventory data were collected from various sources at various spatial scales. The datasets collected were not resampled and are presented in their original form as provided from the contributing agencies, with the exception for a variety of sites that were drawn from coordinates provided by governing agencies.

Process Steps

Process Step 1

CC ID: 496963
Description:

Boundary data were collected from various sources, including NOAA Electronic Navigational Charts, Notices to Mariners, as well as the National Geospatial-Intelligence Agency (NGA) Digital Nautical Charts. Where boundaries were not available in GIS formats, they were digitized from coordinates published in the Code of Federal Regulations, or from paper charts as needed.
