The ICES EcoSystemData system joins several databases on physical, biological and chemical information into one system. The data available in EurOBIS is an extract from the EcoSystemData System of ICES

The Beam Trawl Survey dataset includes age- and length-based catch per unit effort data for commercial fish species in ICES statical rectangles.

Baltic International Bottom Trawl Survey dataset includes age- and length-based catch per unit effort data for commercial fish species in ICES Baltic sub-divisions.

The ICES programme of international herring larval surveys in the North Sea and adjacent areas is in operation since 1967. The main purpose of this programme is to provide quantitative estimates of herring larval abundance, which are used as a relative index of changes of the herring spawning‐stock biomass in the assessment. The larvae surveys are carried out in specific periods and areas, following autumn and winter spawning activity of herring from north to south. Catch data together with specific information like haul position, survey area etc. are reported to the ICES International Herring Larvae database annually. The database contains information about the surveys conducted since 1972. The ICES responsible group for the dataset is WGIPS.

The dataset includes age- and length-based catch per unit effort data for commercial fish species in the Irish Sea.

The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Scottish Rockall Survey.

Biological zoobenthos community data

The dataset includes information about spatial distribution and abundance of fish eggs and larvae in the North Sea based on the data from the North Sea Cod and Plaice egg surveys. The survey aims at studying fish egg and larval distributions in the winter in the North Sea, target species are cod and plaice. <br/> The program was steered by the WGEGGS until 2012 and is currently steered by WGEGGS2.

Biological phytoplankton community data

DOME contains marine environmental data featuring: <ul> <li> North-East Atlantic, Greenland sea, Baltic sea and Norwegian sea <li> Contaminants in biota, sediment and water, fish disease and biological communities <li> Aggregated fish trawl survey data <li>Data spanning the years 1965-2008 </ul>
