The Nautical Archaeology Society is a non-government organisation formed to further interest in our underwater cultural heritage. 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 Society has published The International Journal of Nautical Archaeology since 1972 and also produces the newsletter Nautical Archaeology, which is free to members.
