The Biological Reference Collections (CBR) are located at the Institute of Marine Sciences (ICM-CSIC) in Barcelona. They were created in 1981, thanks to the efforts of Jaume Rucabado, Domingo Lloris and Concepción Allué.

The dataset provides a quantitative list of the benthic macrofauna taxa, identified to species level, which was collected from soft sediments in the Prof. Luiz Saldanha Marine Park (Arrábida, SW Portugal) between 2007 and 2009, at depths ranging from 10 to 100 m, aiming at describing community structure and distribution as well as classifying and mapping benthic habitats according to the EUNIS system.

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

This is a historical dataset regarding Turbellaria species collected by professor Steurer; during his three month's stay in Alexandria. It contains large forms only, all of them being Pollycladida. Some of them could not be well determined, as they were badly preserved and not yet mature.

Every year, Wageningen Marine Research carries out shellfish surveys in the Dutch coastal waters (Wadden Sea, Oosterschelde, Westerschelde and Coastal Zone), investigating the distribution and size of the most important commercial shellfish species. These are mainly mussels, cockles, knife hives and Japanese oysters, but also other species with a certain importance for ecology or fishing are included. In addition, catch data from professional fishing are also collected. The data is used by the government when deciding whether or not to permit fishing.

This dataset includes systematic bird counts data collected from the “Regional Protected Landscape of the Vila do Conde Shoreline and the Mindelo Ornithological Reserve (PPRLVCROM – “Paisagem Protegida Regional do Litoral de Vila do Conde e Reserva Ornitológica de Mindelo”), a protected area in Northern Portugal. Data were collected in winter of 2013-2014 and spring 2014, in 18 observation points (10-minute recording time per point), in which all birds detected by sight and/or sound were recorded. A total of 612 records were made (average of 3.1 individuals per record), collected from 116 sampling events. Fifty-three species of 27 families were recorded.

Monthly time series of phytoplankton species abundance, integrated in the water column at a fixed oceanographic station off Gijón (NW Spain)

This dataset contains counts of Mysidacea (determined at genus level) from two samples from Gazi Bay (October 1994), 1 at Uroa Beach (July 1996) and two at Ambon (April 1996) using a hyperbenthic sledge (0.5m high, mesh width 0.5mm) or hand net. The data were digitized by VLIZ from the original report: Poppe, B. (1997). Taxonomische studie van enkele tropische Mysidacea = Taxonomic study of some tropical Mysidacea. Thesis. Universiteit Gent: Ghent. 19 pp.
