<p>The Thornton measuring buoy is part of the oceanographic component of ICOS Belgium (The Integrated Carbon Observation System), it carries sensors for both LifeWatch and ICOS. Management is organized as part of ICOS, an established and landmark European Research Infrastructure Consortium (ERIC) delivering high quality observations of greenhouse gases in all environmental domains.&nbsp;</p><p>The buoy collects data at approximately 30 minutes frequency and is regularly maintained and calibrated by VLIZ. This dataset includes the 2018 CTD data. Sensors were calibrated pre and post deployment and the analysis of the data alongside the calibrations suggest that no data corrections were needed.&nbsp;</p>

In the framework of the Lifewatch marine observatory a number of fixed stations in the Belgian Part of the North Sea (BPNS) are visited on a monthly or seasonal basis using RV Simon Stevin. A grid of nine stations covers the coastal zone and are sampled monthly. Eight additional stations, located further at sea, are sampled on a seasonal basis. Samples are taken using a 55µm mesh size Apstein net and fixed in Lugol's iodine solution. In the lab, the samples are processed using a VS-4 FlowCAM model at 4X magnification, size range imaged is 55-300µm. The identification of the image data is done with the use of a classifier and followed by a manual validation step. Since May 2017, this dataset provides micro- and phytoplankton observations, mainly covering diatoms, dinoflagellates and cilliates, for the Belgian Part of the North Sea (BPNS).

Dataset includes phytoplankton data collected during cruise 38 (December 1986 - April 1987) on board of R/V Dmitriy Mendeleev.

Dataset includes zooplankton data (limited to order Tintinnida Kofoid and Campbel, 1929) collected during First Ukrainian Antarctic Expedition (March-April 1997) on board of R/V Krenkel.

French benthic invertebrates composition and abundance taxa data are collected during REBENT monitoring surveys on the English Channel / Bay of Biscay coasts and during RSLFAU monitoring surveys on Mediterranean coast. Protocols are implemented in the Water Framework Directive.

Data collection on population size and distribution of cetaceans in Sicily, Ionian Sea, promoted by the MareCamp association thanks to the citizen science initiative "Report a sighting and help the research" through phone and e-mail communications made by yachtsmen and fishers, and also filling in the following online form https://forms.gle/mAx9ZHZDzrPfs9P59 Data here provided were collected in 2008-2019 period. The project is ongoing; sightings are reported in the database only if the advisories have good photos of reference able to distinguish the species and the area of observation. Presence of boats, fishing activities, other species like birds, fish, jellyfish, meteorological and sea conditions are also collected.

The Aves (bird skeletons) collection is part of the SeSAM collections of Senckenberg which combines all collections held at the Senckenberg Natutal History Museum of Frankfurt. This collection contains bird skeletons from all over the world.

This dataset contains a list of species of Ceramiaceae present at the coast of Kenya, Tanzania and the Seychelles sampled between 1985 and 1997. Most specimens have been collected by wading or snorkeling. The data were digitized by VLIZ from the original report: Roels, T. (1998). Taxonomisch-morfologische studie van enkel genera van de Ceramiaceae langs de Oost-Afrikaanse kust = Taxonomic-morphological study of a few genera of the Ceramiaceae along the East-African coast..

Occurrence (presence/absence) of Bryozoa on several substrates (<i>Cystoseira</i>, <i>Posidonia</i> and rocky cliff hard substrate) sampled at Calvi Bay (Corsica) in September 1982 and April 1983. The data were digitized by VLIZ from the original report: Janssen, C.R.; Thielemans, L.K.; Vermeulen, Y. (1983). Bryozoa van de Baai van Calvi (Corsica), in: FKFO Project 2.9007.82. Systematiek en ecologie van mariene organismen: verslag over het tweede werkingsjaar 1983. pp. 59-69.

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