About Us

Headquartered in Astoria Oregon, MAS was created to help document and share maritime history with the public. The Maritime Archaeological Society is a registered 501(c)3 not for profit organization.


The mission of the Maritime Archaeological Society is to seek out, investigate, and document shipwrecks and other maritime archaeological sites; conserve artifacts from those sites, when appropriate; and educate the public in areas of maritime cultural heritage, historic shipwreck preservation, and the science of maritime archaeology.

Purpose and Vision

MAS was created to help state archaeologists document the thousands of shipwrecks and other submerged archaeological sites, and to assist with the conservation of artifacts. We will share our passion for maritime heritage with the public and promote awareness in the importance of maritime archaeology through our community outreach education programs. Additionally, our internal training program will produce qualified volunteers to assist with fieldwork and research opportunities.
