The principle aim of this research was to investigate the morphometry of nematode communities as triggered by a phytoplankton spring bloom deposition in a well oxygenated North Sea sampling station. Length and width measurements are available together with densities.

A regular monthly sampling at the time series station C1 in the Gulf of Trieste, North Adriatic Sea began in 1986. The time series station C1 was initiated by the University of Trieste, and was later taken care by the Laboratory of Marine Biology of Trieste after its formal institution in December 1979 and, since October 2005, by the Department of Biological Oceanography, now Division of Oceanography (OCE) of OGS, Istituto Nazionale di Oceanografia e Geofisica Sperimentale of Trieste. 

Data on pelagic fishes from German North Atlantic cruises from the 1970s to 1980s kept by the Zoological Museum of Hamburg (ZIM Hamburg). The dataset was provided to MAR-ECO by Dr. Heino Fock. Primary reference: Post, A. 1987. Pelagic transects of FRVs "Walther Herwig" and "Anton Dohrn" in the Atlantic Ocean 1966 to 1986. Mitt. Inst. f. Seefischerei d. BfaFi Hamburg, 42: 1-68.

Fal nematode and copepode abundance and environmental data; samples from November and March, from 5 creeks (Restronguet, Mylor, Pill, St Just, Percuil)

The phytoplankton dataset includes samples collected from shallow to shelf Romanian waters, in the period 1975 - 1980, from March to November; there is no similar frequency each year. Dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa.

Data is an assembly of plankton monitoring stations situated between 54° and 58° North along the Danish coasts and in estuaries. There are 6 zooplankton stations that are visited 6 times per year. Samples are analyzed to estimate zooplankton composition and abundance. The individuals are either sized or staged and species is determined to lowest possible taxonomical level. This dataset includes multicellular prokaryotes as well as ciliates and same heterotrophic dinoflagellates

Phytoplankton data collected by the IBSS staff at diurnal stations in the Sukhumi region, Black Sea, in November 1948. This dataset contains abundance data (individuals per liter) for phytoplankton taxa. No additional metadata is available.

Tuna species caught and commercialized by pole and line tuna fishery boats.

In the framework of the OMEX-programme (Ocean Margin Exchange, CEC-MAST II), data were collected on the metazoan meiobenthos along the continental slope of the Goban Spur.

The “Pipeta programme” (named after the Italian commercial trawler used; 300 HP; LOA = 26 m) was started in 1982 by the Laboratory of Marine Biology and Fisheries (LMBF, Italy) and the Institute of Oceanography and Fisheries (IOF, Croatia). The expedition was a fishery-independent trawl-survey of the demersal communities using a bottom otter-trawl net (wing mesh-size: 55 mm; cod-end mesh-size: 22 mm; foot-rope length: 41 m; head-rope length: 32 m). The average towing speed was about 3.5 knots, and the sampling duration was 60 minutes for almost all hauls, with the exception of one haul (sampling duration of 15 minutes). Two successive trawl hauls were performed at each station, with the second towing frequently performed along the same distance but in the opposite direction. Data per stations are given as the mean value of two replicates. The survey was successively named GRUND programme and ended in 2007.
