Located about 1,700 kilometers off the South Carolina shoreline in the Atlantic Ocean, Bermuda resembles a giant fish hook. The eye of the hook in the northeast is formed by Castle Harbour. The smaller enclosed body of water immediately below that is Harrington Sound. Under the water, coral reefs glow bright blue. The coral reflects light, coloring the shallow water blue and green. The Moderate Resolution Imaging Spectroradiometer on NASA’s Terra satellite captured this true-color image of Bermuda on March 4, 2004.
