These movies were originally created to be incorporated into an introductory movie for the Calvert Marine Museum, Solomons, Maryland. The data maps for this movie were compiled by Peter Vogt. The animation was created by Tanya Atwater, using Photoshop and Morph. The animation work was supported by a grant from the National Science Foundation.
