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 eutrophication and acidity, and covers the Baltic Sea. Data were aggregated and quality controlled by "Swedish Meteorological and Hydrological Institute (SMHI)" in Sweden. ITS-90 water temperature and water body salinity variables have also been included ('as are') to complete the eutrophication and acidity data. If you use these variables for calculations, please refer to SeaDataNet for the quality flags: https://www.seadatanet.org/Products/Aggregated-datasets . Regional datasets concerning eutrophication and acidity are automatically harvested, and the resulting collections are aggregated and quality controlled using ODV Software and following a common methodology for all sea regions ( https://doi.org/10.13120/8xm0-5m67 ). Parameter names are based on P35 vocabulary, which relates to EMODnet Chemistry aggregated parameter names and is available at: https://vocab.nerc.ac.uk/search_nvs/P35/ . When not present in original data, water body nitrate plus nitrite was calculated by summing all nitrate and nitrite parameters. The same procedure was applied for water body dissolved inorganic nitrogen (DIN), which was calculated by summing all nitrate, nitrite, and ammonium parameters. Concentrations per unit mass were converted to a unit volume using a constant density of 1.025 kg/L. The aggregated dataset can also be downloaded as an ODV collection and spreadsheet, which is composed of a metadata header followed by tab separated values. This spreadsheet can be imported to ODV Software for visualisation (more information can be found at: https://www.seadatanet.org/Software/ODV ).

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 European 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 Artic Ocean, the North East Atlantic, the Greater North Sea and Celtic Seas, the Baltic Sea, the Mediterranean Sea and the Black Sea. It is produced by the merging of the regional data sets for the above mentioned six regions. Regional datasets were harmonised and validated regionally by: 'Institute of Marine Research - Norwegian Marine Data Centre (NMD)' (Norway), 'IFREMER / IDM / SISMER - Scientific Information Systems for the SEA' (France), 'Aarhus University, Department of Bioscience, Marine Ecology Roskilde' (Denmark), 'Swedish Meteorological and Hydrological Institute (SMHI)' (Sweden), 'Hellenic Centre for Marine Research, Hellenic National Oceanographic Data Centre (HCMR/HNODC)' (Greece) and 'National Institute for Marine Research and Development 'Grigore Antipa' (Romania). 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 European aggregated and harmonized contaminant dataset contains water, sediment and biota profiles and timeseries. The temporal coverage is 1974–2021 for water measurements, 1966–2022 for sediment measurements and 1979–2021 for biota measurements. The European aggregated and harmonized contaminant dataset can be downloaded 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 visualization (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).

This product displays for Cadmium, positions with values counts that have been measured per matrix and are present in EMODnet regional contaminants aggregated datasets, v2024. The product displays positions for all available years.

Gagnaset (data set) ni_vg25v_1.1utg og ni_vg25r_3utg: Vistgerðir á Íslandi (Habitat types of Iceland). Vistgerðakortið sýnir útbreiðslu vistgerða á Íslandi. Vistgerðum á Íslandi er skipt upp í land, ferskvatn og fjörur. Alls hafa verið ákvarðaðar 64 vistgerðir á landi, 17 vistgerðir fyrir ferskvatn og 24 vistgerðir fyrir fjörur. Landvistgerðir skiptast í 12 meginflokka (vistlendi). Innan landvistgerða eru fjórar jarðhitavistgerðir sem finnast á háhita- og lághitasvæðum landsins. Land- og ferskvatnsvistgerðir skiptast í tvö þrep, en fjöruvistgerðir í fimm þrep. Við skilgreiningu og flokkun vistgerða á Íslandi var tekið mið af EUNIS-flokkunarkerfinu (European Environment Agency 2012). Landupplýsingaþekjan fyrir landvistgerðir er á rastaformi (ni_vg25r_3utg), en þekjur fyrir jarðhita, ferskvatns- og fjöruvistgerðir er á vektorformi (ni_vg25v_1.1utg). Vektorþekjurnar eru flestar flákaþekjur, en fyrir ferskvatn er einnig línu- og punktaþekja. Gögn fyrir stöðuvötn (vg2 = V1) eru fjarlægð tímabundið úr niðurhalsþjónustu vegna ágreinings um grunnkort Loftmynda ehf. en þekjan er sýnileg í kortasjá. Náttúrufræðistofnun Íslands leggur með ritinu Vistgerðir á Íslandi fram tillögur að flokkun vistgerða sem á sér fyrirmynd í samræmdri og viðurkenndri flokkun vistgerða í Evrópu. Flokkunin byggir á rannsóknum víða um land með fyrirvara um að bæta mætti í þá þekkingu. Athuga skal að aðgreining landvistgerða með fjarkönnun reyndist erfið, bæði fyrir lítið grónar vistgerðir sem og vel grónar, einkum innan vistlenda. Því má búast við verulegum skekkjum þótt þær séu mismiklar eftir vistgerðum. Nánari útlistun og mat á skekkjum má finna í aðferðalýsingu og á staðreyndasíðum vistgerða í ritinu „Vistgerðir á Íslandi“. Frekari upplýsingar um flokkun og skilgreiningu vistgerða má sjá í ritinu (Jón Gunnar Ottósson, Anna Sveinsdóttir og María Harðardóttir, ritstj. 2016. Vistgerðir á Íslandi. Fjölrit Náttúrufræðistofnunar nr. 54. Garðabær: Náttúrufræðistofnun Íslands) og á vef Náttúrufræðistofnunar Íslands. Í 3. útgáfu vistgerðakortsins 2024 eru eingöngu landvistgerðir endurskoðaðar.
