As we reported last month, the collection features more than 1,000 negatives, including over 700 original glass plates, documenting more than 200 shipwrecks off the Isles of Scilly and Cornwall between 1869 and 1997.
The archive was started by press photographer John Gibson who bought his first camera 150 years ago.
The museum, part of Royal Museums Greenwich, acquired the archive for £122,500 at a Sotheby’s auction.
Royal Museums Greenwich today said it plans to conserve, research and digitise the archive and showcase the images in exhibitions touring museums and galleries, starting in the South West of England.
