Thereâ€™s a database of underwater photographs that you can access for free at the NCCOS website. The online Coral Reef Ecosystem Database, developed and managed by the National Centers for Coastal Ocean Science, provides access to images of coral reef species and habitats, which were taken during studies in Puerto Rico and the U.S. Virgin Islands.
The online database consists of thousands of digital photographs from six years of coral reef field studies. Anyone can access the database which provides high resolution digital photographs of fish, hard and soft corals, hydroids, sea grass, sponges, and other invertebrates, vertebrates and algae which can be directly downloaded via the Internet.
All they ask in return is for users to credit the NOAA CCMA Biogeography Team for the use of their photos.
The NCCOS website is under the auspices of the Center for Coastal Monitoring and Assessment of the National Oceanic and Atmospheric Administration, an agency of the U.S. Commerce Department.
