Arctic region - Contaminants aggregated datasets 1974/2022 v2026

EMODnet Chemistry aims to provide access to marine chemistry datasets and derived data products concerning eutrophication, acidity and contaminants. The importance of the selected substances and other parameters relates to the Marine Strategy Framework Directive (MSFD). This aggregated dataset contains all unrestricted EMODnet Chemistry data on potential hazardous substances, despite the fact that some data might not be related to pollution (e.g. collected by deep corer). Temperature, salinity and additional parameters are included when available. It covers the Norwegian Sea, Barents Sea, Greenland Sea and Icelandic Waters. Data were harmonised and validated by the 'Institute of Marine Research - Norwegian Marine Data Centre (NMD)' in Norway.
The dataset contains water and sediment profiles. The temporal coverage is 1974–2011 for water measurements and 1974–2022 for sediment measurements.
Regional datasets concerning contaminants are automatically harvested and the resulting collections are harmonised and validated using ODV Software and following a common methodology for all sea regions ( https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4 ). Parameter names are based on P01 vocabulary, which relates to BODC Parameter Usage Vocabulary and is available at: https://vocab.nerc.ac.uk/search_nvs/P01/ .
The harmonised dataset can be downloaded as as an ODV spreadsheet, which is composed of a metadata header followed by tab separated values. This spreadsheet can be imported into ODV Software for visualisation (more information can be found at: https://www.seadatanet.org/Software/ODV ). In addition, the same dataset is offered also as a txt file in a long/vertical format, in which each P01 measurement is a record line. Additionally, there are a series of columns that split P01 terms into subcomponents (substance, CAS number, matrix...).This transposed format is more adapted to worksheet applications (e.g. LibreOffice Calc).

Spatial distribution of meiobenthos in the Voordelta (October 1988)

Meiofauna composition and overview of nematoda genera found in Grevelingen and the Oosterschelde area on 17 and 19 October 1988. The data were digitized by VLIZ from the original report: Jian, L. (1989). The study in the spatial distribution of meiobenthos in the Voordelta (the Southern Bight of the North Sea). MSc Thesis. VUB: Yerseke. 77 pp.
Samples were taken on six stations from two areas (Grevelingen and Oosterschelde area) in the Voordelta (Southern Bight of the North Sea). At each station, three boxes corer (14.7cm diam.) were taken and out of each box corer, three replicate cores (2.4 cm diam.) were randomly taken (total of 54 core samples to be analysed). From each sample, meiofauna composition (densities of the 16 higher taxa encountered) and nematode genera (up to 65 in this study) have been determined.
Cefas09 - Effects of paint-derived tributyltin (TBT) on structure of estuarine nematode assemblages in experimental microcosms

This experimental laboratory study assessed the effects of different levels of paint-derived TBT, and different modes of exposure, on estuarine nematodes.
Fauna was exposed to two types of treatments (mixture and deposit), containing uncontaminated sediment and sediment spiked with paint-derived TBT.
Meiofauna of the Gulf of Trieste-Slovenia

The database contains abundance of main meiofaunal groups and of harpacticoid copepods separately. There are also data present from a recolonisation study.
This database is a product of 25 years of meiofaunal research of the Gulf of Trieste-TS Gulf. The data are based on coastal transects from 1-15m depth, sampling of offshore waters of the TS Gulf-31 stations, long term study at a single location in the central part of TS Gulf-10 years, and numerous other partial studies in the vicinity of mariculture site, harbour and other areas.
Soft-bottom macrozoobenthos from the littoral zone of the Natura 2000 MPA "Ropotamo", Southern Bulgarian Black Sea (2013)

Abundance (individuals/m2) of macrozoobenthic taxa at littoral/upper infralittoral soft-bottom stations in the Natura 2000 MPA "Ropotamo" (BG0001001), southern Bulgarian Black Sea. The data were collected during field surveys of IBER-BAS in 2013 as part of project COCONET. The dataset also contains a visual description of sediment type at the stations, and a habitat type classification to EUNIS L3.
Project COCONET has two main themes: 1 - identify prospective networks of existing or potential marine protected areas (MPAs) in the Mediterranean and the Black Seas, shifting from a local perspective (centred on single MPAs) to the regional level (network of MPAs) and finally the basin scale (network of networks). The identification of the physical and biological connections among MPAs will elucidate the patterns and processes of biodiversity distribution. Measures to improve protection schemes will be suggested, based on maintaining effective exchanges (biological and hydrological) between protected areas. The national coastal focus of existing MPAs will be widened to both off shore and deep sea habitats, incorporating them into the networks through examination of current legislation, to find legal solutions to set up transboundary MPAs. 2 - explore where offshore wind farms (OWF) might be established, producing an enriched wind atlas both for the Mediterranean and the Black Seas. OWF locations will avoid too sensitive habitats but the possibility for them to act as stepping-stones through MPAs, without interfering much with human activities, will be evaluated. Socioeconomic studies employing ecosystem services valuation methods to develop sustainable approaches for both MPA and OWF development will also be carried out, to complement the ecological and technological parts of the project, so as to provide guidelines to design, manage and monitor networks of MPAs and OWF. Two pilot projects (one in the Mediterranean Sea and one in the Black Sea) will test in the field the assumptions of theoretical approaches, based on previous knowledge, to find emerging properties in what we already know, in the light of the needs of the project.

Occurrence of Eukaryotes in the size fraction 5-20 micrometres, collected worldwide during the Tara Oceans expedition (2009-2013) using a ring net and analysed by environmental High Content Fluorescence Microscopy (e-HCFM).

The Tara Oceans project sampled contrasting ecosystems of the world oceans during a three-year expedition (2009-2013), collecting environmental data and plankton, from viruses to metazoans, on board the 36-metre Tara Schooner. It surveyed 210 ecosystems in 20 biogeographic provinces, collecting over 35,000 samples of seawater and plankton. Samples were later analysed using modern sequencing and state-of-the-art imaging technologies.
We are keen to thank the commitment of the following people and sponsors who made this singular expedition possible: CNRS, EMBL, Genoscope/CEA, VIB, Stazione Zoologica Anton Dohrn, UNIMIB, ANR (projects POSEIDON, BIOMARKS, PROMETHEUS, and TARA-GIRUS), FWO, BIO5, Biosphere 2, agnès b., the Veolia Environment Foundation, Region Bretagne, World Courier, Illumina, Cap L'Orient, the EDF Foundation EDF Diversiterre, FRB, the Prince Albert II de Monaco Foundation, Etienne Bourgois, the Tara schooner and its captain and crew. Tara Oceans would not exist without the continuous support of the participating 23 institutes.

Multi-decadal shifts in fish community diversity across a dynamic biogeographic transition zone

A 21-year fisheries-independent monitoring dataset was used to explore fish community diversity across a latitudinal gradient to quantify how diversity has changed and relate those changes in diversity to changes in the abiotic environment. Additionally, this study spans a biogeographic transition zone, providing insight into future species assemblages across regions of relatively high species diversity.
Location: Indian River Lagoon, Florida, USA Methods: Spatial and temporal beta diversity was quantified latitudinally with “best derived breaks” determined by using chronological cluster analyses.  Multiple indices of alpha diversity were quantified, including species richness, Shannon diversity, Simpson diversity, and Pielou’s evenness. AIC model selection and environmental fit tests were performed to link patterns of diversity and species assemblages with the abiotic environment. Results: Evidence of a biogeographic transition zone was supported by data spanning the entire study period; the largest break in species assemblage occurred near 28°N. Fine scale analyses using small and large seine catches were noisier than broad analyses but indicated a northern shift in location of the biogeographic transition zone. Beta-diversity was generally dominated by species turnover/balance versus nestedness/gradient components, implying that changes were driven by species sorting associated with the physical environment. Excluding the summation of all environmental variables, temperature and dissolved oxygen best describe patterns of diversity and species composition. Main Conclusions: Over years less affected by disturbances, large and small seine catch data suggest the fish community assemblage and location of the biogeographic transition zone has shifted 9 km and 21 km to the north. If the trends observed in these years were to continue from 1999 until the year 2100, a 111 km to 243 km shift in fish communities could be expected. Variation in rates of movement based on gear type suggest novel species assemblages could ensue.
Abundance and biomass of benthic infauna as part of the North Channel habitat mapping project, 2017

This dataset contains information on infaunal abundance and biomass from sediment grabs in North Channel as part of a larger, more comprehensive habitat mapping project. This survey was carried out over two days in 2017 by the Agri-Food - Biosciences Institute (AFBI) on the RV Corystes. A 0.1m2 Day Grab was used to collect the sediment samples. Particle size analysis (PSA) and Carbon - Nitrogen analysis were carried out. The infaunal samples were sent away to accredited taxonomic laboratories to be identified and weighed. There were many commercially and biologically important species found in the samples for example Modiolus modiolus (Northern Ireland priority species) and a few non-native species such as Goniadella gracilis. There were also a few records of species that are not formally recorded in the UK e.g. Syllis licheri. The most abundant species recorded was the polychaete Sabellaria spinulosa. The polychaete species Syllis armillaris was present in all 12 samples taken.
Survey of North Wales and Pembrokeshire Tide Influenced Communities

Marine biological surveys of seabed and shore habitats in four areas exposed to strong tidal currents around southwest and northwest Wales, made in summer 2002 and 2003.
Marine biological surveys of seabed and shore habitats in four areas exposed to strong tidal currents around southwest and northwest Wales, made in summer 2002 and 2003. Survey work focused on rocky reefs and tidal rapids, and recorded the extent, quality and composition of the biotopes and communities. The results forms the basis for CCW Contract Science Report 611. 

Tidal Rapids are a UK Biodiversity Action Plan feature and rocky Reefs are an Annex I feature under the Habitats Directive (1992). These features are of conservation importance and the data collected during this survey is used to help define conservation objectives and inform decisions regarding protection and management. 

The survey was conducted on the shore or by diving. Survey methods were based on the standard Marine Nature Conservation Review (MNCR) techniques using in-situ identification of conspicuous species and description of habitat and community characteristics. Subtidal and intertidal components of the fieldwork were carried out separately. Further details of these standard methodologies are given in MNCR Rational and Methods (Hiscock 1996). Each site survey was recorded immediately on standard MNCR recording forms. Work carried out for CCW under contract by Coastal Assessment, Liaison - Monitoring (CALM), Jon Moore.

Norfish: Norwegian/Swedish Bohuslän Herring Landings 1520–1808

NorFish is a European Research Council (ERC) Advanced Grant led by Prof Poul Holm in Trinity College Dublin, focuses on the premise that a 16th century shift in marine fish pricing and supply in conjunction with the Little Ice Age and lowering of sea temperatures not only rise to the North Atlantic Fish Revolution but also forms one of the first documented examples of the disrupting effects of globalisation and climate change. The project examines the role of the Fish Revolution for a range of inter-related aspects of North Atlantic history, with NorFish’s interdisciplinary team drawing on archaeology, history, cartography, geography, and ecology to develop interpretative frameworks that synthesise a broad spectrum of source data to assess the overall objective of the project. NorFish’s interdisciplinary team draws on archaeology, history, cartography, geography, and ecology to assess the objectives of the project.
Today, Bohuslän is a Swedish region by the Skagerrak coast between the Oslo fjord and modern Gothenburg. In the medieval period to 1658 it was ruled by Norwegian and Danish kings. The region enjoyed a large herring fishery in the second half of the 16th century. In 1658, under the Treaty of Roskilde, Bohuslän was ceded to the Swedish kingdom. Under Swedish control, commercial herring fishing grew again in the latter half of the 18th century with several fishing communities springing up along the coast.
