The contribution of the African institutions to the Ocean Biogeographic Information System (OBIS) and the World Register of Marine Species (WoRMS) was improved considerably through the organization of focused workshops during which experts from ODINAFRICA institutions in Africa developed databases on marine molluscs, sponges, and decapods. The work formed the basis for creation of the African Register of Marine AfReMaS (www.marinespecies.org/afremas/Species – AfReMaS), which already had more than 24,300 as at the end of August 2013. Some of the institutions have made progress in developing national marine biodiversity databases and availing them online or through the AfrOBIS node, which is one of the global nodes of OBIS. A project to digitize marine biodiversity data collected in the Gulf of Guinea (in particular national waters of Guinea) by ex-Soviet Union research vessels was implemented and the data generated included in OBIS.
