Ireland’s Marine Atlas is developed and maintained by the Marine Institute with funding by the Government of Ireland. This work is part supported by the Irish Government and the European Maritime & Fisheries Fund as part of the EMFF Operational Programme for 2014-2020. The atlas provides a one-stop-shop to view and download marine environmental data relevant to reporting under Ireland’s Marine Strategy Framework Directive (MSFD). The aim of the European Union’s MSFD directive is to protect more effectively the marine environment across Europe through the establishment of “good marine waters”. Data in Ireland’s Marine Atlas has been guided by the European Directive on harmonising environmental data across Europe within a spatial data infrastructure known as INSPIRE. INSPIRE Data Specifications (Data Models) have been used to manage data to the categories visible under THEMES in the atlas. Many of the layers displayed in the Atlas are also used in the National Marine Planning Framework (NMPF). This framework aims to bring together all marine-based human activities, outlining the government’s vision, objectives and marine planning policies for each marine activity. The NMPF report details how these marine activities will interact with each other in an ocean space that is under increasing spatial pressure, ensuring the sustainable use of our marine resources to 2040.

Eutrophication status of the OSPAR of 2007 zones of metropolitan France. Data collected in the course of "initial assessment" phase of the MSFD.

The statistical analysis used (Principal Component Analysis followed by a classification method) to identify groups common to all months and describe the evolution of these groups during the year. The data used allows for monthly tables showing the selected parameters, calculated over the entire geographic area with a resolution of 0.1 °. This method identifies 10 hydrological landscapes present at various times of the year, and characterized by homogeneous hydrological conditions.

The analysis concerns the assessment of the overall state of the coastal and transitional waters of the Western Channel and the Bay of Biscay. It results from the combination of the ecological status and the chemical status of each water body according to the rules of the European Water Framework Directive (WFD). The most recent assessment of the state is presented in the DCE Loire-Bretagne atlas. Earlier reports are available in annual archives.

The chemical status of a coastal water body (coastal water or transition water) is determined by the most declassing of the defined states for heavy metals, pesticides, industrial pollutants and other pollutants taken into account by the WFD . The assessment is done once per management plan (once every six years). The most recent assessment of the state of the chemical state is presented in the DCE Loire-Bretagne atlas. Earlier reports are available in annual archives.

3D seasonal temperature range (in ° C) obtained by objective analysis (interpolation) of the raw data in situ, near the seafloor. Within the Bay of Biscay Challenge and the programme of the Operational Coastal Oceanographic Centre Prévimer, the services of SISMER DYNECO-PHYSED of IFREMER have built a joint hydrological database of the Bay of Biscay, from CTD measurements, Bouteilles, XBT / MBT and Profileurs from multiple global data centres to achieve a climatological atlas of the region for temperature and salinity.

This is a compilation of OSPAR habitat point data for the northeast Atlantic submitted by OSPAR contracting parties. The compilation is coordinated by the UK's Joint Nature Conservation Committee, working with a representative from each of the OSPAR coastal contracting parties. This public dataset does not contain records relating to sensitive species (e.g. Ostrea edulis) in specific areas, or where data are restricted from public release by the owner's use limitations. This version (v2020) was published in July 2021.

Excel file containing CPR data from Standard Areas B4,C3,C4,D3,D4,D5,E4,F4 for the plankton Calanus finmarchicus and helgolandicus, total traverse (small) copepods, total large copepods, Phytoplankton Colour Index and Cnidaria (presence denoted by a 1, absence by a zero). All taxa are from 1980, except Cnidaria which are from 2011. Dataset is in the format of sample level data, with each row being a discrete sample, with a sample being 3m3 filtered seawater, and 10nm of tow. For each row, a sample has the following information, starting at column a: Standard area of sample, sample id, latitude (decimal degrees) of sample mid point, longitude (decimal degrees) of sample midpoint, sample midpoint date and local time, year of sample, month of sample, then plankton abundance values (or PCI index or cnidaria presence/absence). All taxa have been looked for during the period this dataset spans, so zero values represent true absence.
