All these data are freely available for the scientificcommunity in order to reusing them through the initiativeEMODnet Ingestion3 (Data Ingestion Portal) and SeaDataNet4infrastructure.The use of single-beam echo-sounders is now combined withmulti-beam ones in order to gain data accuracy. The combinedresults in regional Data Terrain Models (DTM) have also beenintegrated into EMODnet Bathymetry2 This work adds valuableinformation that completes previous multi-beam surveys,thereby, improving the resolution of less sampled seafloorareas in the Spanish waters (Fig. 2).REFERENCES:[1] Octopus Version 1.5.3: https://wwz.ifremer.fr[2] https://www.emodnet-bathymetry.euMETHODOLOGYINTRODUCTIONSeabed mapping techniques have improved overthe last decades due to the increasing needs ofhigh-resolution data. In the framework ofoceanography surveys carried out by the R/V R.Margalef (Fig.1) performed by the Spanish Instituteof Oceanography (IEO) since 2014.The navigation trajectories have been recordedusing a continuous single-beam echo-sounder tomeasure the depth along its tracks. The systemintegrates the bathymetry measurements and theship GPS position. They are mainly held aroundSpanish territorial waters.[3] https://www.emodnet-ingestion.eu[4] https://www.seadatanet.orgFig. 2. Combined map showing all track points based on bathymetryFig. 1.
