ChEssBase is a dynamic relational database for all deep-water species from chemosynthetic ecosystems (hydrothermal vents, cold seeps and other reducing environments such as whale carcasses, sunken wood or OMZs) being constructed from the ChEss project (Biogeography of Deep-Water Chemosynthetic Ecosystems) within the Census of Marine Life initiative.
