    The dataset provides a quantitative list of the macrozoobenthic taxa collected in the infra and circalittoral sandy bottom off Ericeira (central Portugal) in May 2001. The fauna was identified to species or family level. The aim was to characterize the macrozoobenthic composition of sandy sediments potentially suitable for beach nourishment, in order to assess the environmental impact of the dredging operations on the benthic communities.

    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.

    Data on incidental sightings of cetaceans reported to the Institute of Marine Research by letter or telephone, as well as information from newspapers, have been collected since 1967. From the late 1970s, data have also been obtained from research vessels, coast guard vessels, some fishing vessels and inspectors. These reports contain basic information on date, position and species, but also additional information such as group sizes. These sightings are not useful for assessing abundance, but might reveal distributional aspects. Most of the reports come from the northern areas (Barents Sea); this is clearly related to the distribution of the activities which form the basis for this kind of reporting.

    Data is an assembly of plankton monitoring stations situated between 54° and 58° North along the Danish coasts and in estuaries. There are multiple phytoplankton stations and 15 of them are maintained by 2016, although the data set also contains data of several discontinued stations. Each phytoplankton station is visited 1 to 4 times per month over a period of 25 years for some of the stations (two times per month is the norm). Samples are analyzed to estimate phytoplankton composition and abundance. The cell volume is determined for a sub group of cell of each species encountered, thus estimating a cell volume that is applied to the entire sample

    The RSL dataset results from the monitoring activities undertaken by the "Réseau de Suivi Lagunaire en Languedoc-Roussillon" RSL project. The dataset contains mainly data relating to the level of eutrophication along the French Languedoc-Roussillon area.

    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

    Qualitative and quantitative composition and spatial distribution of the zooplankton community for 32 stations sampled on 18-19 April 1978 in the Belgian part of the North Sea.The data are digitized from technical reports in the frame of the 4DEMON project.

  • Categories  

    Phytoplankton data, species composition, abundance (cells/l) (SDN:P01: PU00M00Z) and biomass (mg/m3) (SDN:P01: WWBMM00Z) collected at coastal stations located in the 1n.m. Bulgarian Black Sea area and stations on a coastal-open sea transect in the Bulgarian Black Sea region, including the EEZ, within EC, FP7 Project SESAME.

    Field survey on juvenile bivalve densities; date: 8-11 October 2007; vessel: RV POSEIDON (operated by IFM Geomar, Germany); sampling stations: 20 stations in OWEZ and 10 stations in each of the 5 reference areas R2, R3, R4, R5, RL

    A macrozoobenthos species list is provided, based on datasets originated from infra and circalittoral samples (4 to 120 m depth) collected in the marine waters from north to south of mainland Portugal. Species composition, density and wet weight biomass are provided. The data were collected in the framework of the of the EEMA Programme, whose aim was the Ecological Assessment of Water Masses in mainland Portugal.
