-
High resolution composite DTM based on single beam, multi beam and Lidar covering Norderney and waters in proximty. All data was acquired in the year 2016. Data used:SDN:CPRD:1850_DGM_Norderney_2016
-
Multibeam bathymetry collected from Asköfjärden and Fifång Deep, east of Askö Island in southern Stockholm archipelago. The data were collected with Stockholm University research vessels (RV) Electra and Skidbladner between 2012 and 2018 for multiple purposes. Some of the data were collected as a part of a course in marine geophysical mapping at Stockholm University. The processing of the raw data was carried out using the Qimera software by QPS. The data have been cleared for public release by the Swedish Maritime Administration.

Satellite-derived intertidal bathymetry for the Danish Wadden on the West coast of Denmark
-
The data have been acquired with a SeaBat RESON 7125 (frequency 450kHz and depth up to 150 m) multibeam echosounder mounted on board of the research vessel "Minerva 1" (party chief F. G. Falese) between 27 september and 5 october 2016. The main objective of this cruise was the search of relict sand deposits potentially exploitable for beach nourishment on these continental shelves. Weather and marine conditions were fair during the acquisition.

Bathymetric data were collected on the Gorringe Bank, located along the Europe-Africa obliquely convergent plate boundary offshore SW Portugal. The high-resolution swath bathymetry dataset allowed the investigation of the shallow-depth structure of the Horseshoe Seamounts. Data were collected by means of the MBES system Reson SeaBat8101. The MBES was hull-mounted on a 60 meters long vessel. The MBES has 101 beams 1,5° x 1,5°; the operational frequency was 240 kHz. A LandStar 12 channel DGPS system was used for ship positioning and a motion sensor TSS-DMS02-05 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 SVP20 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.
