The primary aim for this data collection was to built a database and to apply GIS techniques in the Gulf of Trieste and North Adriatic Sea

Taxonomy database of the Western and Sea Scheldt from the of the Netherlands Institute of Ecology; Centre for Estuarine and Marine Ecology; Department of Ecosystem Studies

This data collected in the framework of a PhD thesis were collected between 1934 and 1936. Scientists from the Hellenic Centre of Marine Research computed the dataset afterwards (Vatova, A. 1949).

This dataset was compiled in order to monitor long-term responses of the macrobenthos community to the environmental quality changes in the Northern Adriatic Sea

The data is the integration of three different subdatasets i.e. the impact of dredging on benthic macrofauna (1979 data), comparison of macrobenthos between major European tidal estuaries (1991-92 data) and ecological monitoring of macrobenthos in an area affected by the effluents of a nuclear power plant (2004 data)

Global information system on fishes, including key information on all fish taxa. FishBase on the web contains practically all fish species known to science.

This dataset is part of a national project on the consequences of the Navarino Oil spill, in 1994 at the Gialova Lagoon, Ionian Sea. The Cretan coasts were studied from May 1987, in order to assess the level of their environmental degradation due to touristic and other anthropogenic activities

Comparison dataset of Animalia in the North Sea, the English Channel and the Celtic Sea.

Partial contribution from the British Oceanographic Data Centre's databases (see below for details on status).

We assembled occurrence records (presence-only) for all four horseshoe crab species in Asia and Eastern America from our own observations, collaborators, scientific networks as well as through publishing a scratchpad site at http://horseshoecrabs.myspecies.info/. For many species, numerous distribution records exist in the literature, and we manually geo-referenced additional occurrence data from these sources.
