The Smithsonian’s National Museum of Natural History and Digitization Program Office, in collaboration with The Hydrous, a non-profit organization whose mission is to create ‘open access oceans,' worked to digitize and create online experiences for a collection of coral and reef-dwelling specimens. The purpose of this project is to make ecosystems and collection more available and visible, and to preserve these type specimens digitally for future generations and research. The specimens are split across 5 lessons/modules that mimic a dive profile (immerse to ascend) and progress together, but can also be explored individually.
