252_CNR-38-Gorringe_HR

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.
