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.

The nematode communities from 102 stations in the Southern Bight of the North Sea, sampled between 1972 and 1984, are examined. On the whole, 456 species, belonging to 159 genera and 37 families were found.

Taxonomic Information System for the Belgian coastal area. Biogeographical information on (mainly) Belgian species. Focus area of the dataset spans from north of Wimereux (northern France) to the Scheldt estuary (southern Netherlands).

Density, biomass, population structure and brood size were determined for Mysid shrimp populations in the Scheldt-estuary.

Data on the ecology of the hyperbenthos community of the Scheldt estuary were derived from research projects on this matter (1988-2001).
