Using Geographic Information System tools, scientists and researchers can zoom into to an image like this to reveal fine details about the location, health, and variety of submerged aquatic vegetation in a given area. This image of Redfish Bay, Texas near Corpus Christi--part of the new Texas Coastal Bend map--shows seagrass (green), oyster reefs (pink), sand bottom (yellow), mangroves (magenta), and salt marsh (light blue).
