The colors of sound

One would be forgiven for thinking that measurements of the ocean floor just produce numbers. It turns out that the data acquired by sound (sonar) can be translated into some truly beautiful graphics. Check out this gorgeous digital terrain model created by Ian Colvert, a physical science technician with Coast Survey’s Navigation Response Team 6. Colvert produced the image file by processing data acquired with the team’s multibeam sonar during a recent hydrographic survey project.

The digital terrain model depicts the wreck of the freighter Fernstream, a 416-foot motor cargo vessel that sank after a collision near the entrance of the San Francisco Bay in 1952. NRT6 surveyed Fernstream as part of a recent study – identifying potential polluting shipwrecks – conducted by the Office of National Maritime Sanctuaries and the Office of Response and Restoration.

This project helps agencies prioritize threats to coastal resources. It also adds to our ability to assess the historical and cultural significance of shipwrecks. And it happens to make some dazzling graphics in the process.

UPDATE, June 26, 2013: We’ve had some requests for more information about the wreck itself. Here’s a chartlet that provides that information.
