Institute of Biology of the Southern Seas has huge amount of different multidisciplinary datasets collected since 1871. At the moment only part of them is digitized and put to the integrated data and information management system of the institute. This dataset presents biological data such as zooplankton and phytoplankton samples data from different scientific cruises performed by the IBSS ships and from cruises of other organizations where IBSS group worked. The database is being populated with newly digitized and obtained data on the permanent basis. These data were put to the institute’s information system and were made available for the scientific community with the support of the Flemish Government within the OceanUkraine project (http://www.vliz.be/projects/ocean-ukraine)
