The data have been acquired with a Seabat 8101 (240 kHz) multibeam echosounder mounted on board of a little boat (chief scientist F.L. Chiocci; party chief A. Bosman). The main objective of the cruise was the recognition of the submarine hazard features placed offshore the Cirò Marina-Punta Alice (Ionic Calabrian Coast).

This composite Digital Terrain Model (cDTM) is a high resolution bathymetry dataset highlighting measurement of depth of water in the ocean. This cDTM covers the Irish Sea off the coast of County Louth in Ireland. The EMODnet high resolution DTM covers bathymetry surveys completed between 2002 and 2019. Bathymetric data collected on board research vessels using multi-beam and single-beam echosounder instrumentation. Raw bathymetry processed within CARIS software to produce bathymetry products subsequently converted to NetCDF cDTM for EMODnet. Acquisition, processing and product delivery follows IHO standard s44 Edition 5. cDTM is composed of six (6) images “merged simply” using GLOBE software. INFOMAR (Integrated Mapping for the Sustainable Development of Ireland’s Marine Resource) is a twenty year programme to map the physical, chemical and biological features of Ireland’s seabed established in 2006. INFOMAR is funded by the Department of Communications, Climate Action and Environment (DCCAE), and delivered by joint management partners Geological Survey Ireland and the Marine Institute. The programme is the successor to the Irish National Seabed Survey (INSS) which ran between 1999 and 2005. INFOMAR concentrates on creating integrated mapping products related to the seabed.

Multibeam bathymetry in Tangafjørður, Faroe Islands.

The DTM was generated from two dataset acquired around Ischia and Procida Islands (Gulf of Naples, Italy). The dataset were collected within CARG (Geological CARtography) Project by means of the MBES system Reson SeaBat8125. The MBES was pole-mounted on a 6 meters long vessel. The MBES has 240 beams 1°x1°; the operational frequency was 455 kHz. A LandStar 12 channel DGPS system was used for ship positioning and a motion sensor Ixea Octans3000 was used to provide corrections for attitude data. A Sound Velocity Sensor was installed near the transducers thus providing realtime sound speed for beam steering. A sound velocity profiler Reson SVP15 was lowered through the water column every 6–8 h to get the velocity profile required for the depth computation. The bathymetric data were processed using the PDS2000 software. Data de-spiking was carried out without the application of automatic filters in order to preserve data accuracy and resolution.

The DTM is produced with Kongsberg multibeam echosounder survey, acquired in 2015 by Marine Research Ltd. The resolution is 1/256 arc-minutes (~7.2m). It is located in Costinesti, Romania, on the coastal region of the Black Sea. Depths are referenced to the Mean Sea Level and the coordinates are expressed into the WGS84 reference frame.
