Ocean Portal by the Smithsonian Institution
http://ocean.si.edu/

Ocean Portal is a unique, interactive online experience that inspires awareness, understanding, and stewardship of the world’s Ocean, It has been developed by the Smithsonian Institution’s National Museum of Natural History and more than 20 collaborating organizations. You are among the first wave of visitors to the Portal, an experience which they hope will empower you to shape and share your personal Ocean experiences, knowledge, and perspectives. The input you provide through feedback modules and comment boxes will help them to shape future Ocean Portal content and functionality. Like the Ocean, which is made of millions of marine species, your comments, questions, and clicks will help to bring the Portal closer to the vastness and variety of the Ocean itself.
