This is a biological data base of the Institute of Oceanographic Sciences Deacon Laboratory, U.K. The data are mainly open ocean, with some data from upwelling regions off N.W. Africa and in the Arabian Sea. Data were collected using nets, mainly the IOS RMT1+8 combination net or its multiple version and represent 94000 records in 2100 species.
