The EMODnet Bathymetry World Base Layer (EBWB) service is a gridded representation of worldwide bathymetric and topographic coverage adapted for a better representation of seabed morphological features. Based on modern WMTS schema, it allows a fluid and powerful rendering. For the global oceans EBWB1 is composed of the 2018 EMODnet Bathymetric grid around Europe (approx. 100m resolution) and uses the GEBCO 2019 grid (approx. 500m resolution) elsewhere in the marine environment. Land coverage is based on a combination of 30 arc second ASTER GDEM, SRTM3, EU-DEM, and Global 1 second world-wide water body map for the topographic part. This compilation of publicly available data sources have been merged and pre-tiled for rendering, at 10 levels of zoom starting from 1/24th of an arcminute (approx. 75m resolution). The EBWB1 service is available in non-projected system (Lat, Long, WGS84: EPSG:4086), Web Mercator (EPSG:3857), Inspire compliant ETRS-EALA projection (EPSG:3035) and projections adapted to both poles (ESPG 3031 and 3996) Service URL: https://tiles.emodnet-bathymetry.eu/wmts/1.0.0/WMTSCapabilities.xml

DTM data source was created by taking contour lines and spot soundings from Norwegian Electronic Navigational Charts. NOTE: Data east of appr.

Maas West Outer Vlissingen, South part. There are sand waves. Surveyed by one of the Hydrographic Survey Vessels of the Royal Netherlands Navy.

Multibeam bathymetry of Haifa Bay. Description of processed data sources: the data come from the IOLR's R/V Etziona www.ocean.org) with a Kongsberg-Simrad EM1002 (90 kHz, 111 beams). The data is the property of the Israeli Government, Ministry of National Infrastructures, which was renamed to the Ministry of Energy and Water. The original data is classified. The navigation is all with real-time corrections and is <1 m. The appropriate oceanographic measurements were made with my AML CTD as well as a Valeport SV. The analysis was all done with CARIS HIPS/SIPS. The data include another survey in deeper water with an ELAC Nautik Gmbh. SeaBeam 3050 50 kHz system, a year ago aboard the R/V Mediterranean Explorer (www.ecoocean.com) . It covered some 7,000 sq. km. from depths of ~500 to 1600 m.

Multibeam data acquired in 2007 during the SVAIS cruise on board the R/VHespérides with a Simrad EM12 echo-sounder

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset that covers GEOMARGEN-2 surveys. Multibeam data acquired in 2013 on board the R/V Angeles Alvariño with a Kongsberg EM710 echo-sounder

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset that covers CASCADES-I, CASCADES-II, COSTEM-1, COSTEM-2, COSTEM-3, COSTEM-4, FORMED-2, FORMED-4 and FORMED-6 cruises. Multibeam data acquired in 2008, 2009, 2010, 2011, 2013, 2014 and 2015 on board the R/V Sarmiento de Gamboa and the R/V García del Cid with an Atlas Hydrosweep DS-3 and an Elac Seabeam 1050D echo-sounder.

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset that covers SALTFLU cruise. Multibeam data acquired in 2012 on board the R/V OGS Explora with a Reason 8150 echo-sounder

Systematic survey performed by IDROSPED with Singlebeam EchoSounder
