The purpose of this study was to follow the gradient of the benthic algal vegetation from the head to the mouth of the Borgafjördur. Attention was paid to the zonation patterns, algal associations and the species distribution. These data were also compared to the vegetation of other Icelandic fjords.

In 1997 and 1998 soft-bottom fauna of the arctic glacial fjord Kongsfjorden was extensively sampled and major communities were identified along the fjord axis, which were believed to be related to the diminishing influence of the glacial activity. This set of data was collected as part of a PhD programme and was the result of repeated sampling in search for natural or climate driven community changes.

A total of 648 incidental catches of Black Sea cetaceans in fishing gear have been recorded in the northern Black Sea off the coasts of Crimea between 1997 and 2009.

Zooplankton from the Belgian Part of the North Sea was sampled monthly in 2009 and 2010 at 10 monitoring stations, using a WP2 net (57cm, 200µm mesh size), which was towed in an oblique haul from bottom to surface.

Frequency, density and biomass of copepoda species for several stations in the Oosterschelde, Grevelingen and the Eems-Dollard sampled between 1976 and 1983. The data were digitized by VLIZ from the original report: Willems, K.A. (1989). Verspreiding, ecologie en gemeenschapsstructuur van benthische copepoden in het Delta-gebied en de Eems-Dollard (Nederland). PhD Thesis. Rijksuniversiteit Gent, Faculteit der Wetenschappen: Gent. 2 vol. (440, 198) pp.

Abundance of phytoplankton species and related environmental parameters for 8 zones in the Southern North Sea between October 1974 and October 1978. The data were digitized from technical reports in the frame of the 4DEMON project.

This data set provides a list of species of the genus <i>Padina</i> that were sampled at the coasts of Saudi-Arabia, Oman, Socotra, Kenya, Zanzibar (Tanzania), Seychelles, Mauritius, La Réunion and South Africa between 1985 and 1999. In total, eleven species were identified. The list also contains the herbarium codes of the species. Sampling was done by snorkeling, walking or SCUBA diving. The algae were removed from the substrate using a knife and put in plastic bags or lobster bags. The data were digitized by VLIZ from the original report: Muylle, J. (2000). Taxonomische en biogeografische studie van het genus Padina (Dictyotales, Phaeophyta) in de westelijke Indische Oceaan. Taxonomic and biogeographical study of the genus Padina (Dictyotales, Phaeophyta) in the west Indian Ocean.. MSc Thesis. Rijksuniversiteit Gent. Faculteit Wetenschappen: Gent. 222 pp.

Species list with remarks on the frequency of occurrence and ecology of the species for the pier of Zeebrugge in 1977 and 1978. The data were digitized by VLIZ from the original report: De Vos, D.; Coppejans, E. (1980). Recente inventaris van de benthische wieren (Cyanophyta, Chlorophyta, Phaeophyta, Rhodophyta) van de pier van Zeebrugge = Inventaire récent des algues benthiques (Cyanophyta, Chlorophyta, Phaeophyta, Rhodophyta) du môle de Zeebrugge.

An annotated check-list is given of Ascidiacea species occurring deeper than 2000 m in the seas bordering Europe.

This dataset contains presence/absence information of infaunal bycatch from seed mussel stock (Mytilus edulis) assessment surveys off the Outer Ards Peninsula in Northern Ireland. The seed mussel survey is carried out each year and this particular dataset contains the bycatch information from initial ground truthing (dredge) on these surveys from 2017-02 to 2018- 07.
