COMARGIS is the Information System of COMARGE (COntinental MARgin Ecosystems on a worldwide scale), a field project of the Census of Marine Life. The core of the system is a relational database implemented in ORACLE. Additional software help the users uploading, retrieving or updating data in the database. The whole system is derived from Biocean, a database developed and maintained by the Deep-Sea Department and the French Oceanographic Data Centre at Ifremer, Brest.
