The NAS is dedicated to advancing education in nautical archaeology at all levels; to improving techniques in excavating, conservation and reporting; and to encouraging the participation of members of the public at all stages.

The Nautical Archaeology Society is a non-government organisation formed to further interest in our underwater cultural heritage. We are a registered charity based in the United Kingdom, but with strong links to sister organisations around the world. (The Charity Commission for England and Wales Reg. No. 264209 and for Scotland Reg. No. SC040130)

We aim to preserve our archaeological heritage in the marine environment, by acting as a focus for coastal and marine archaeology. To do this we need to involve everyone - divers and non-divers, scientists, historians and anyone with an interest. Our underwater heritage is not renewable, and is at constant threat from natural and human agencies.

Preserving a record of the past is vital, and it is important that this record is as accurate as possible. To achieve this we aim to improve archaeological techniques and encourage publication and research. We publish a members' newsletter of events (ISSN 0602-6098), and a learned journal, The International Journal of Nautical Archaeology (ISSN 1057-2414), which welcomes substantive contributions to the art from around the world.

Through these means the NAS aims to reveal our underwater heritage, allowing everyone to benefit from this unique and fascinating resource.
