    The High Resolution Layer Tree Cover Density (TCD) dataset provides information on the proportional crown coverage per pixel at 100 meter spatial resolution and ranges from 0% (all non-tree covered areas) to 100%, whereby Tree Cover Density is defined as the "vertical projection of tree crowns to a horizontal earth’s surface“. This product is an aggregation of its corresponding high resolution dataset. This dataset is provided annually starting with 2018 in 100 meter rasters (fully conformant with the EEA reference grid) in 100 x 100 km tiles covering the EEA38 countries. High Resolution Layer Tree Cover and Forest product is part of the European Union’s Copernicus Land Monitoring Service.

    This product displays for Naphthalene, median values since 2012 that have been measured per matrix and are present in EMODnet regional contaminants aggregated datasets, v2024. The median values ranges are derived from the following percentiles: 0-25%, 25-75%, 75-90%, >90%. Only "good data" are used, namely data with Quality Flag=1, 2, 6, Q (SeaDataNet Quality Flag schema). For water, only surface values are used (0-15 m), for sediment and biota data at all depths are used.

    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.

    The High Resolution Layer Grassland (GRA) raster product provides a binary status layer of grassland/non-grassland mask. This grassy and non-woody vegetation baseline product includes all kinds of grasslands: managed grassland, semi-natural grassland and natural grassy vegetation. It does not include temporary grasslands, which are masked out using the corresponding Ploughing indicator (PLOUGH), indicating on the number of years since a pixel was last ploughed. This dataset is provided annually starting in 2017 with 10 meter rasters (fully conformant with the EEA reference grid) in 100 x 100 km tiles covering the EEA38 countries. High Resolution Layer Grasslands product is part of the European Union’s Copernicus Land Monitoring Service. Confidence layer available for the dataset. This dataset includes data from the French Overseas Territories (DOMs)

    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 1970–2024 for water measurements, 1966–2023 for sediment measurements and 1972–2022 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).

    The Copernicus High Resolution Layer Tree Cover Precense Change (TCPC) 2018-2021 raster product provides information on the change between the reference years 2018 and 2021 and consists of 4 thematic classes (unchanged areas with no tree cover / new tree cover / loss of tree cover / unchanged areas with tree cover). The class 255 = outside area is predefined by the 100m boundary layer and remains unchanged. This layer for previous reference year compraissions is called Tree Cover Change Mask (TCCM). This dataset is provided in 20 meter rasters (fully conformant with the EEA reference grid) in 100 x 100 km tiles covering the EEA38 countries. The production of the high resolution forest layers was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme. Confidence layer available for the dataset. This dataset includes data from the French Overseas Territories (DOMs)
