Maryland Maritime Archeology ProgramMaryland Maritime Archeology Program

As part of the state Department of Planning and housed in the Maryland Historical Trust, the Maryland Maritime Archeology Program (MMAP) was created in 1988 in response to the National Abandoned Shipwreck Act which gave states that had management programs in place, title to significant historic shipwreck remains within their waters.  In addition to shipwrecks, the MMAP searches for, inventories and manages the State's other submerged cultural resources. These include prehistoric sites, historic structures such as buildings, bridge, and wharf remains.  Maryland’s waters cover a range of vessels from native log canoes to colonial merchantmen and warships, and even relatively modern shipwrecks of historic importance.

MMAP actively undertakes cooperative endeavors with numerous groups and agencies at local, state, and federal levels to promote wise management as well as public education and outreach. These partnerships include the U.S. Navy; the National Park Service; the U.S. Army Corps of Engineers; the Maryland State Highway Administration; the Maryland Department of Natural Resources; maritime, historical and archeological societies; dive clubs; metal detecting groups; and local and regional schools.

In addition to finding and studying submerged cultural resources, MMAP actively manages individual and collections of sites.  The U-1105 Black Panther Historic Shipwreck Preserve is an example of a submerged site that the Trust manages through and agreement with the U.S. Navy.


Most of the work that MMAP carries out would not be possible without the help and support of volunteers. 

Currently, the Trust has awarded two non-profit organizations – Maritime Archeological and Historical Society, and the Institute of Maritime History – with non-capital grants to survey and synthesize archeological data on parts of Maryland waters.  MMAP maintains a database of interested volunteers and sends out information to those volunteers when projects come available. 

Interested persons should click here to fill out the volunteer form.  Volunteers need not be interested in diving, as archeological surveys and data management requires skills in boat handling, recording of artifacts, and a range of computer skills.

State and federal laws protect submerged historic and archeological resources located on Maryland bottomlands.  In Maryland, State waters include tidal waters up to the mean high tide line and three miles from the coastline, and non-tidal waters within the boundaries of the state that were navigable under the laws of the United States as of April 28, 1788, up to the ordinary high water mark.  The Trust regulates and manages all prehistoric and historic cultural remains in, partially in, or submerged beneath State waters.  Additionally, MMAP is responsible for the administration of the Submerged Archeological Historic Property Act and its implementing regulations as well as applications for research, recovery, or construction projects, site assessments, and evaluations for National Register eligibility.  MMAP also assists governmental agencies and their program clients to meet their statutory historic preservation responsibilities through the project review and compliance process.

MMAP works continuously to survey and study the wide variety of submerged cultural resources that are located on or under Maryland’s bottomlands.  Information from these projects is made available to the public in the form of survey and archeological reports, informational brochures, posters, and exhibits.

Currently, MMAP is finishing the survey of Maryland’s ocean waters, which includes the Atlantic Ocean ranging from the shoreline to three nautical miles off shore.  This multi-year project was made possible through partnerships with the National Park Service’s Assateague Island National Seashore and Maryland Department of Natural Resources’ Coastal Program.  In June 2009, MMAP staff and volunteers will be surveying the final 20 square mile section of the Atlantic off Assateague Island.
