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

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

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).

The main aim of the REDIT I campaign was to assess the geographical extend of the distribution of the polychaetous Serpulid Ditrupa arietina. Nevertheless, all macrofauna >1mm was identified.

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

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

The ICES/HELCOM Intercalibration Exercise provided a series of replicate samples from one single station in Kiel Bay from May 1995

The Hellenic Centre of Marine Research collected samples in the context of a Number of National and EU-funded projects. The datasets covers qualitative temporal data from Polychaete worms in the Aegean and Ionian Sea.
