EMODnet Digital Bathymetry (DTM 2018) - Tile B7

The "EMODnet Digital Bathymetry (DTM) - 2018" 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 9400 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 satellite images. 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 September 2018 contained > 27.000 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: EMO, EMO (without GEBCO data), ESRI ASCII, ESRI ASCII Mean Sea Level, XYZ, NetCDF (CF), RGB 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.

Cartographie des principaux peuplements sublittoraux du secteur de Plogoff (Source Belsher T., Hamon D., Guillaumont B., 1980-1981) - Echelle 1/25000

Cette cartographie des principaux peuplements sublittoraux du secteur de Plogoff constitue la synth├¿se de l'├®tude men├®e par l'Ifremer et publi├®e sous forme papier en 1987.
Pour cette ├®tude, des photographies sous-marines associ├®es ├á des pr├®l├¿vements par plong├®es ont permis de caract├®riser et de quantifier les principales composantes bios├®dimentaires. Ces prospections terrain ont ├®t├® r├®alis├®es entre juin 1979 et juin 1980. Neuf ensembles bios├®dimentaires ont pu ├¬tre distingu├®s.
Cette carte a fait l'objet en 2010 d'une num├®risation dans le cadre du SINP Mer (Syst├¿me d'Information sur la Nature et les Paysages, volet Mer), avec le soutien du REBENT (REseau de surveillance de la flore et de la faune BENThique marine).
Acoustic mapping of the seabed of the Menai Strait. North East Menai.

The section of the Menai Straits that were surveyed were divided into three parts.

The hardness/roughness isopleths were combined using CAMRIS GIS to produce a composite map showing 7 types of group (very hard/very rough; hard/rough; moderately hard/moderately rough; moderately soft/moderately smooth; soft/moderately rough; soft/smooth; very soft/very smooth).
A map for the whole of the survey area was followed by a map showing the biotope types as observed using the remote video, which are as follows (SA = superabundant; A = abundant; C = common; O = occasional)

Sand/shell: Medium fine sand with shell: very silty.
Coarse sand/silt: Coarse sand: very silty.
Gravel: Barren
Silty cobble: Silt accretion (A); Cerianthus (O-C); Urticina (O-C).
Silty cobble/rich: Silt accretion (A); sponges (Haliclona, Halichondria) (C); hydroids (C); Urticina (O-C).
Boulder/cobble sponge: Similar to above, but with sponges C-A.
Cobble/bounder faunal turf: Hydroids (C); Tubularia (O); Alcyonium(O); Flustra(O).
Cobble hydroid turf: Short turf of hydroids (C-A).
Cobble Pomatoceros: Pomatoceros and barnacles (A).
Bedrock/boulder silt sponge: Similar to boulder/cobble sponge above, but on bedrock/boulder.
Boulder Laminaria: Small Laminaria hyperboraea (C); red algal turf (C).
Bedrock sponge/Flustra: Bedrock with encrusting sponges (C-A) and Flustra (O-C).
Bedrock Mytilus. Small Mytilus (A-SA); Asteria(C-SA); encrusting corralines (O).
Bedrock and faunal turf: Hydroids (C); Tubularia(O); Alcyonium(O); encrusting and branching sponges(O-C).


The maps were subsequently transposed into EUNIS in 2006 using expert judgement.
Presence of Cockleareas in the Dutch wadden Sea

The data is based on the monitoring of cockle beds bij cockle-fishermen. Per 200m-square the presence of cockles is counted in the period from 1980 untill 2005. Information about the original data can be found in the report: EVA2-rapport RIZA/2004.028 Bodemgesteldheid en mechanische kokkelvisserij in de Waddenzee; L. Zwarts e.a..
