The composition and distribution of the macrobenthic amphipod, mollusc and polychaete fauna in the Evros Delta have been investigated. The distribution of species showed a zonation mainly related to the degree of "confinement".

The dataset contains data on the presence of macrobenthos from 2 stations in the Monolmni Lagoon in the Ervos Delta which were sampled monthly in 1998.

Historical quantitative benthos grab samples from the Southern Baltic Sea, collected by Polish researchers. The dataset was digitised at the Christian-Albrechts-University Kiel; Leibniz Institute of Marine Sciences; Marine Ecology Division; Benthos Ecology section.

Historical benthic dredge samples from the southern baltic and the Gulf of Gdansk

Historical benthic samples from the Baltic Sea

Surveys of benthic invertebrates of the Southern Irish Sea were carried out in 1989 and 1991. Both quantitative and qualitative samples were taken for faunal and sediment analysis

Historical quantitative benthos grab samples from the Southern Baltic Sea, collected by German researchers. The dataset was digitised at the Christian-Albrechts-University Kiel; Leibniz Institute of Marine Sciences; Marine Ecology Division; Benthos Ecology section.

The original dataset objective is the sampling of reference stations for large-scale annual surveys of petroleum installations.

Free-living nematode fauna of lake Grevelingen, the Eastern and Western Scheldt was examined over a period of one year in the framework of a PhD thesis.

Deep-sea sampling in 2009 onboard the R/V Sarmiento de Gamboa in the three Mediterranean basins. A combination of 2 samplers was used to collect the benthic megafauna: an otter-trawl Maireta system (OTMS) and an Agassiz dredge. The OTMS is a 1-warp benthic otter-trawl designed to work seamlessly on high depth grounds: its stretch mesh size at the cod-end is 40mm, with an outer cover of 12mm, to allow retrieval of small-sized fractions of megafauna. The net total length is 25m, with an horizontal opening of 12.7m and a vertical opening of 1.4m. Trawls were conducted at 2.6 to 2.8 knots. The Agassiz dredge had a 2.5 m horizontal opening and 1.2 m vertical opening, a net mesh size of 12 mm, and was trawled at 2.0 knots.
