Satellite-derived intertidal bathymetry for the Tagus estuary near Lisbon Portugal

Satellite-derived intertidal bathymetry for the Danish Wadden on the West coast of Denmark

Gridded multibeam data acquired during scientific surveys and transits of French research vessels from 1992 to 2017 off the French Caribbean Islands.

Gardline Geosurvey Limited was contracted to survey the Dogger Bank Offshore Wind Farm (OWF) Area between 04-Apr-2013 and 02-Aug-2013, comprising the Tranche C zonal surveys. The aim of the surveys was to carry out a geophysical investigation that would broadly assess the entire developable area of the zone. Seabed information was required to inform the site selection process and enable preliminary foundation design to be undertaken. The geological data acquisition programme was carried out on M.V. Sea Surveyor, which sailed from Hull and returned to Blyth, and M.V. Vigilant which sailed from, and returned to, Great Yarmouth upon completion of survey operations. The Crown Estate is the data owner and copyright holder.

High resolution (1/512 minute ~ 3.6m) bathymetry dataset from the Mineplat 4 cruise onboard IPMA RV Noruega. Portugal southern continental shelf, off Alentejo coast, 24 March to 4 April 2019. Depths between 60 and 110m. Seabed sediments sampling was performed during daytime and multibeam mapping during the night, with a Reson T50-P multibeam echosounder. Depths are referenced to the Portuguese Chart Datum (2m below MSL) and WGS84 horizontal reference frame. Position and attitude data (GNSS+Inertial via Applanix OceanMaster POSMV) was post-processed with POSPAC.

The data have been acquired with a SeaBat RESON 8125 (455kHz) e Seabat RESON 8160 (50 kHz) multibeam echosounders mounted on board of the research vessel "Universitatis" (chief scientist F.L. Chiocci; party chief F. Falese). The main objective of this cruise was the search of relict sand deposits potentially exploitable for beach nourishment on these continental shelves. Weather conditions were good during the acquisition.
