    A study that focuses on the seasonal community structure of the macrobenthic molluscs at the marine-lagoonal environmental gradient that takes place at Kalloni solar saltworks (Lesvos Island, NE Aegean Sea, Greece).

    Phytoplankton monitoring in the South Adriatic (Adricosm-STAR project), 2008-2009. Discrete water samples are taken at multiple depth layers. The samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance and species composition of phytoplankton were estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 200-320-400x final magnifications.

    The AMORE project contributes to the implementation of an integrated land-coastal zone research methodology to assess and predict the eutrophication level of the coastal North Sea and the associated undesirable effects. The ultimate aim is to reduce the current context of uncertainty in which decisions to counteract the eutrophication of the NS and protect its natural resources are made. Process-level field and laboratory-scale experiments were conducted to improve the basic knowledge on mechanisms through which a change in nutrients (in terms of N:P:Si NO3:NH4 inorganic:organic N ratios) induced modification in the phytoplanktonic community structure and hence the functioning of the whole planktonic food-web. For this the MUMM station 330_a has been monitored for a period of three years.

    This dataset contains a list of species of the Codiales sampled at the coasts of Kenya, Zanzibar and the Seychelles between 1985 and 1993. Sampling was done by walking, snorkeling or SCUBA diving. The data were digitized by VLIZ from the original report: Van den heede, C (1994). De Codiales (Chlorophyta) van Kenya, Zanzibar en de Seychellen. The codiales (Chlorophyta) of Kenya, Zanzibar and the Seychelles.. MSc Thesis. Rijksuniversiteit Gent. Faculteit Wetenschappen: Gent. 160, 74 platen pp.

    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.

    The REBENT dataset results from the monitoring activities undertaken by the "Réseau benthique" REBENT project. The dataset contains mainly data relating to seabed habitats and associated benthic biocenosis living along the the French coastal area's.

    Dataset originated from field surveys carried out from May to October 2001, to assess the seasonal variations in the population structure of four species of intertidal harpacticoids (Paraleptastacus kliei, Huntemannia jadensis, Heterolaophonte minuta, and Stenhelia palustris) at three sites in the middle intertidal zone of Chernorechenskaya Bay (White Sea) with different sediment compositions.

    Phytoplankton data collected by the IBSS staff near Sochi (Mamaika. Matsesta. Sochi river's mouth), Black Sea, during three surveys in 1974 and 1975. Samples were taken in the area of deep sea outfall of Sochi. This dataset contains abundance data (individuals per liter) and biomass (mg/m³) for phytoplankton taxa. Also size records are given for some of them. No additional metadata is available.

    The dataset comprises data on the substrate type, temperature, salinity and benthos from 77 samples colected in 3 fixed points (P1 - 44.2357 Lat. N, 28.6288 Long. E, depth - 1.5 m; P2 - 44.2388 Lat. N, 28.6363 Long. E, depth - 4.5 m; P3 - 44.2416 Lat. N, 28.6447 Long. E, depth - 8 m) in the period 20.10 1959 - 2.11.1961, in Mamaia sector (Constanta, Romanian Black Sea Coast). The sediment samples were taken with a Van-Veen grab, the sampling size of the first 28 samples was - 0.1 m2, while for the rest of 29 - 77 samples it was 0.05 m2.. The samples have been preserved with 10% buffered formalin, then sieved through a 1 and 0.25 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (individuals count, density and wet weight biomass per square meter) for 30 macrobenthic species and 6 supraspecific groups.
