Did you know that there are some five and a half million acres of our National Parks that are underwater? There are sunken ships and aircraft. There are remnants of industry and mining. There are coral reefs and underwater caverns.

The Submerged Resources Center of the National Park Service is where these water resources are explored and documented. Underwater photography is crucial in the understanding of what lies beneath the surface, and images taken by the SRC Staff are essential not only for mapping and documenting, but to help the parks address issues and solve problems.

This week, the Traveler’s Lynn Riddick sits down with Brett Seymour, the Submerged Resources Center Deputy Chief and Audio-Visual Production Specialist who has spent some thirty years with the Park Service, photographing the mysteries below the surface.
