The mandate of the Maritime Museum of the Atlantic is to create for all an awareness, appreciation and understanding of Nova Scotia's marine heritage through collection, preservation, research, interpretation and exhibition.
The Collections Unit at the Museum plays a significant role in fulfilling this mandate, maintaining and developing the collection, preserving artifacts and objects, and conducting research in order to develop exhibits and facilitate interpretation.
The Museum preserves artifacts by keeping them in a carefully monitored environment. More active conservation is carried out by curatorial staff. The Museum has a full-time boatbuilder to restore and conserve the small craft collection and conservation and restoration work is on-going aboard CSS Acadia.
