Black Sea - Contaminants aggregated datasets 1974/2022 v2023

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 Black Sea. Data were harmonised and validated by the ‘National Institute for Marine Research and Development "Grigore Antipa" in Romania.		
The dataset contains water, sediment and biota profiles. The temporal coverage is 1974–2021 for water measurements, 1990–2022 for sediment measurements and 2008–2019 for biota 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).
EMODnet Digital Bathymetry (DTM 2020) - Tile G1

The "EMODnet Digital Bathymetry (DTM)- 2020" is a multilayer bathymetric product for Europe’s sea basins covering:
•  the Greater North Sea, including the Kattegat and stretches of water such as Fair Isle, Cromarty, Forth, Forties,Dover, Wight, and Portland 
•  the English Channel and Celtic Seas  
•  Western Mediterranean, the Ionian Sea and the Central Mediterranean Sea 
•  Iberian Coast and Bay of Biscay (Atlantic Ocean) 
•  Adriatic Sea (Mediterranean) 
•  Aegean - Levantine Sea (Mediterranean). 
•  Madeira and Azores (Macaronesia) 
•  Baltic Sea 
•  Black Sea 
•  Norwegian and Icelandic Seas 
•  Canary Islands (Macaronesia) 
•  Arctic region and Barentz Sea

The DTM is based upon more than 16360 bathymetric survey data sets and Composite DTMs that have been gathered from 49 data providers from 24 countries riparian to European seas. Also Satellite Derived Bathymetry data products have been included derived from Landsat 8 and Sentinel satellite images. Areas not covered by observations are completed by integrating GEBCO 2020 and IBCAO V4. 
The source reference layer in the portal viewing service gives metadata of the data sets used with their data providers; the metadata also acknowledges the data originators. The incorporated survey data sets itself can be discovered and requested for access through the Common Data Index (CDI) data discovery and access service that in December 2020 contained > 30.000 survey data sets from European data providers for global waters. This discovery service makes use of SeaDataNet standards and services and have been integrated in the EMODnet portal (https://emodnet.ec.europa.eu/en/bathymetry#bathymetry-services ). The Composite DTMs are described using the Sextant Catalogue Service that makes also use of SeaDataNet standards and services. Their metadata can be retrieved through interrogating the Source Reference map in the Central Map Viewing service (https://emodnet.ec.europa.eu/geoviewer/ ). 
In addition, the EMODnet Map Viewer gives users wide functionality for viewing and downloading the EMODnet digital bathymetry such as:
• water depth (refering to the Lowest Astronomical Tide Datum - LAT) in gridded form on a DTM grid of 1/16 * 1/16 arc minute of longitude and latitude (ca 115 * 115 meters).
• option to view depth parameters of individual DTM cells and references to source data
• option to download DTM in 58 tiles in different formats: ESRI ASCII, XYZ, EMODnet CSV, NetCDF (CF), GeoTiff and SD
• option to visualize the DTM in 3D in the browser without plug-in
• layer with a number of high resolution DTMs for coastal regions
• layer with wrecks from the UKHO Wrecks database.

The EMODnet DTM is also available by means of OGC web services (WMS, WFS, WCS, WMTS), which are specified at the EMODnet Bathymetry portal.  
The original datasets themselves are not distributed but described in the metadata services, giving clear information about the background survey data used for the DTM, their access restrictions, originators and distributors and facilitating requests by users to originator.

The JNCC is the UK Government's wildlife adviser, undertaking national and international conservation work on behalf of the three country nature conservation agencies Natural England, Scottish Natural Heritage and the Countryside Council for Wales. In addition to leading the MESH project, JNCC's marine habitat mapping work involves the production and subsequent revision of the National marine habitat classification for Britain and Ireland which was also fully incorporated into the EUNIS classification system. Other work involves the provision of advice to the UK conservation agencies, government bodies and others on various mapping techniques and technologies. JNCC contributes to International Council for the Exploration of the Sea (ICES) work on marine habitat mapping and has produced a Marine Monitoring Handbook that holds procedural guidelines to many of these techniques and technologies.
ICES EcoSystemData

The ICES EcoSystemData system joins several databases on physical, biological and chemical information into one system.
The data available in EurOBIS is an extract from the EcoSystemData System of ICES
The EcoSystemData system joins the physical, biological and chemical conditions of the sea by storing and processing oceanographic, contaminants and biological effects of contaminants in seawater, sediment and biota, and biological community abundance data into one system. For many years these data were held and managed in separate systems and one of the main goals of EcoSystemData is to function as an integrated repository where different types of data can coexist and interact for the multiple purposes, e.g. map spatial planning, ecosystem management decision support tools, climate change studies and fisheries management.
Diversity and geographic distribution of marine planktonic copepods

A complete interactive database of all described marine planktonic copepods.
A complete interactive database of all described marine planktonic copepods, including : 

Taxonomic classification with references 
Illustrated and referenced species database 
A geographic distribution in the world's oceans and seas, with division in zones and subzones
A complete bibliography including taxonomic and ecological aspects

The database was compiled from a bibliographic search of 5861 relevant scientific publications, taking into account the actual state of synonymy.

It comprises 319 genera, and 2463 studied species with geographic distribution. 

The species cards are progressively enriched with Figure plates, favouring the rare documents. 

This inventory treats all the species listed starting from the work of Giesbrecht (1892 [actually "1893"], after Holthuis - Vervoort, 2006) up to 2007/2008. It is based on the analysis of more than five thousand publications, either of a purely systematic nature, or dealing with ecology. It cannot be regarded as exhaustive, nor safe from errors or lapses of memory, but the consulted publications correspond to a world "sampling". In the case of certain species the critical analysis starting from the literature does not make it possible to be sure about their validity or their synonymy; these cases are indicated in the remarks for each one of them.
MADS - macroalgae on stone reefs

Data on species areal cover of macro-algae.
Macroalgae

It is possible to find macroalgae vegetation almost everywhere in Kattegat and the Belt Sea area and the western Baltic Sea where stone reefs are common. Salinity and light play an important role structuring the algae communities as do wave exposure at low water depth.

In Denmark more than 300 species of red, brown and green algae species is registered. Macroalgae forest on stone reefs are considered as important habitats for a large number of fish and animals.

Eelgrass
Eelgrass is the most common marine angiosperm in Danish coastal waters where it dominates the vegetation on sandy substrates.

Eelgrass plays an important part in coastal areas due to its large productivity and biomass.

Eelgrass meadows are nursery areas for fish and invertebrates and the well-developed rhizomes contribute to stabilising the sediment and thereby reducing coastal erosion.

Eelgrass grows from the coast and down to maximum depths that depend on water clarity. In the inner parts of estuaries, the deepest eelgrass patches typically occur at a depth of around 3 m, while along open coasts eelgrass typically occurs down to 5-6 m depth. The deepest registrations of eelgrass in Danish coastal waters are found at about 10 m.

The cover of eelgrass typically describes a bell-shaped pattern with depth. Cover is low close to the coast where physical exposure generates loss of biomass, and in deeper water where light limits growth. Thus, maximum cover occurs at intermediate depths where exposure is moderate and light levels are still considerable.

The monitoring programme in connection with the "Action plan for the marine environment" includes measurements of the depth distribution of eelgrass as well as of the percentage coverage of eelgrass. Reductions in nutrient loads are expected to reduce the biomass of phytoplankton, thereby improving water clarity and allowing eelgrass to grow at greater depths and obtain higher coverage in deeper waters.

MADS - Marine zooplankton

Dataset contains species abundances of microzooplankton and mesozooplankton
Zooplankton
The zooplankton can be divided in two groups the microzooplankton < 200 µm and the mesozooplankton > 200 µm. 
The microzooplankton is composed of protozoa ( e.g. ciliates and heterotrophic dinoflagellates) and the smaller developmental stages of the mesozooplankton. The microzooplankton is normally collected by water bottles together with the samples for phytoplankton.

The mesozooplankton is the zooplankton fraction > 200 µm. The mesozooplankton is composed by two main groups, the holoplankton that is pelagic throughout their life cycle and the meroplankton composed by pelagic larvae stages of benthic organisms. The mesozooplankton is normally dominated by copepods, cladocera and meroplankton. The mesozooplankton is normally collected by plankton nets or submersible pumps.

Data
Species abundance of both microzooplankton and mesozooplankton are avaible.

MADS - Marine benthic soft-sediment macrozoobenthos

Data contain abundance (number of individuals) and biomass (wet weight or dry weight) information.
Benthic macrofauna
Investigations of benthic macrofauna, in particular from soft sediments, have a long tradition, with the first quantitative studies in Scandinavian waters performed over 100 years ago.

Benthic macrofauna is important as food for demersal fish, the cycling of organic matter and contaminants, and not the least as an indicator of environmental quality.

Benthic macrofauna is normally defined as organisms retained on 1 mm (European standard) or 0.5 mm sieves. It includes invertebrates over a wide size spectrum; from large crustaceans like Norway Lobster and large bivalves like the Ocean Quahog, to small worms like polychaetes and oligochaetes.

Benthic macrofauna also forms a substantial part of marine biodiversity, with more than 500 species in the soft sediments of Kattegat and the Danish estuaries.

The general aims of CSEMP are to

Detect long-term spatial and temporal trends in physical, biological and chemical variables at selected estuarine and coastal sites 
Support consistent standards in national and international monitoring programmes for marine environmental quality 
Establish appropriate protective regulatory measures 
Coordinate and optimise marine monitoring in the UK 
Provide a high quality chemical and biological data set from the UK’s marine environment
Irish deepwater survey

The purpose of the survey is to investigate the impact of fishing on the abundance and biological parameters of deepwater species.
Fisheries science services recommenced the Irish deepwater survey program in September 2006. The purpose of the survey is to investigate the impact of fishing on the abundance and biological parameters of deepwater species. The survey is also used to collect ecological data such as hydrography, bottom sediment type and distribution of deepwater invertebrates. This will help to describe the ecosystem that the deepwater fish species inhabit.
Irish anglerfish survey

The objective is to provide an estimate of the total weight of the highly valuable Anglerfish stocks and to provide information on how the stock changes from year to year.
This is a new survey which began in December 2006 and extends from the waters to the south west of Ireland, the Porcupine Bank and the North West of Ireland. It is conducted in close collaboration with colleagues from the Marine Laboratory, Aberdeen who survey the west coast of Scotland, the Rockall Bank and into the Northern North Sea.

The objective is to provide an estimate of the total weight of the highly valuable Anglerfish stocks and to provide information on how the stock changes from year to year. Ultimately, this information is presented to the ICES stock assessment working groups and will form an important source of information for future fisheries advice.
Contaminants in the Irish marine environment: water

Nephrops underwater TV survey

This is the spatial dataset for UWTV Survey stations in the areas known as the Aran Grounds, the Irish Sea and the Celtic Sea which are surveyed on three separate surveys.
The prawn (Nephrops norvegicus) are common around the Irish coast occurring in geographically distinct sandy/muddy areas were the sediment is suitable for them to construct their burrows. Nephrops spend a great deal of time in their burrows and their emergence from these is related to time of year, light intensity and tidal strength. This is the spatial dataset for UWTV Survey stations in the areas known as the Aran Grounds, the Irish Sea and the Celtic Sea which are surveyed on three separate surveys.

The Marine Institute has been using underwater television surveys to independently estimate abundance, distribution and stock sizes of Nephrops on the Aran Grounds and Western Irish Sea. Data are also collected on Nephrops behaviour and the impact of fishing activity on the seabed.
Acoustic survey of herring and blue whiting

Acoustic surveys are generally carried out on spawning and pre-spawning aggregations of fish.
Acoustic surveys are generally carried out on spawning and pre-spawning aggregations of fish. Outside of the spawning season many pelagic species are generally very scattered over a large geographical area and difficult to detect using acoustic methods. A cruise track is first formulated with data from previous surveys, commercial catch data and the help of the fishermen and fishing industry. This is the spatial dataset of the Acoustic pinger transects.

Redshank nesting on saltmarshes in Britain

This survey was undertaken to establish the breeding abundance and conservation status (i.e. stable, increasing or declining) of redshank nesting on saltmarshes in Britain.
This survey was undertaken to establish the breeding abundance and conservation status (i.e. stable, increasing or declining) of redshank nesting on saltmarshes in Britain. The redshank is a species of conservation concern in Britain and Europe. In Britain and Ireland redshank can be found breeding on wet grassland and saltmarshes. Redshank on lowland wet grassland habitats is well known and this survey highlights the importance of saltmarsh habitats for breeding redshank.63 saltmarsh sites were surveyed, representing around 5% of the total area of saltmarsh in Britain. Sites were selected to include a range of saltmarsh habitats evenly distributed around Britain. No formal random sampling protocol was used to select sites. The entire dataset is presented at 100m resolution. Data points for this dataset represent the central point of the site surveyed.The survey was carried out in the 1996 breeding season (between 15 April and 31 May).Numbers of redshank breeding at each site were measured using standard methods developed by Green et al. (1984) and Green (1986). The mean number of redshank counted on survey visits up to 31 May was used as an estimate of the peak number of pairs with nests. The abundance of other species such as wildfowl and other waders were also captured as part of this survey, but these data do not occur as part of this dataset. These data have been gathered by trained field-workers and are therefore of a high quality. These data have also been mapped and checked for sensitivities and typographical/geographical errors.This survey highlighted that saltmarshes support circa 45% of the national population of redshank breeding in Britain. Since a previous survey carried out in 1985, there has been a 22.9% decline of redshank breeding on saltmarshes. The decline is thought to be caused by an increase in grazing pressure of saltmarshes, it was therefore suggested that mitigation procedures such as habitat creation and changes in agricultural management measures were required.
Aegean Sea Cruise Benthos

This is the dataset from the sampling that was conducted within the framework of the European Community MATER program (Mass Transfer and Ecosystem Response). At September 1997, six stations were sampled in the southern (depth 900 - 2200 m) and seven in the northern Aegean Sea (depth 100 - 1200 m).
The data send to Eurobis only contains abundances. The original datafiles also contain dry and wet weigth biomass values. It was not included in Eurobis as the data is a somation per species per station, whereas the abundances are available per sample.
Number of species and observations per IHO Sea Area based on EurOBIS data

For each IHO Sea area, intersecting with the ERMS scope, the total number of unique species and the total number of distribution records together with the same values for the mammals, birds, reptiles, benthos, zooplankton, phytoplankton, macroalgae en angiosperms.  The calculations were done with SQL queries, on the complete sea areas. These areas have been clipped with ERMS, which created a little error on the results on intersecting seas, not completely within the study area.
Nematode and pore-water geochemistry data from the Darwin MV collected during the JC10 Cruise 2007 and processed by Ugent

These data were gathered in the framework of the HERMES project (WP3: cold seep systems) and its successor; i.e. the HERMIONE project (WP5: chemosynthetic ecosystems). The paper describing these data is also part of the PhD thesis of Ellen Pape
Macrofauna of the Nordic Margin collected during the Vicking Cruise 2006 and ARK XXII Cruise 2007 and processed by IFREMER

Noorvegian margin datasets (Vicking and ARK) were part of the Hermes project. The objective was to provide an comprehensive and integrative study of the faunal communities of the different habitats of the Haakon Mosby Mud Volcano and a first description of communities of the Storrega pockmarks. This study was combined with microbial (MPI) and chemical (MPI, Ifremer) characterisation of the same habitats.
New Records of Polychaetes from the South Part of Suez Canal, Egypt

Faunistic analysis of benthic samples were obtained during a trip to the south part of Suez Canal,
Egypt, during April, 2007, which revealed the presence of 82 polychaete species, 18 of them are considered as new records for the Egyptian waters. In order to achieve this study fouling components and sediments samples were collected by Van Veen grab (0.5 to 8 m depths), from six stations extending from Deversoir to Port Toufiq.
