3288_Mineplat_HR_A - Alentejo shelf - 7m res.

High resolution (1/256 minute ~ 7m) bathymetry dataset from the Mineplat 3 cruise onboard IPMA RV Noruega. Portugal southern continental shelf, off Alentejo coast, 8 to 20 June, 2018. Depths between 80 and 160m. High resolution multichannel seismics and magnetic data acquisition performed during the daytime and multibeam mapping 24h/24h, with a Reson T50-P multibeam echosounder.

Depths are referenced to the Portuguese Chart Datum (2m below MSL), horizontal coordinates in the WGS84 reference frame. Position and attitude data (GNSS+Inertial via Applanix OceanMaster POSMV) was pos-processed with POSPAC.

Measure description

GPS-RTK was assured during most of the cruise. Surface Sound velocity (near the transducer) continuously acquired for beam steering.

Evaluation method description

GNSS/Inertial recorded data was post-processed with Applanix POSPAC, SV profiles were made every 8 to 12 hours. Crossing/overlaping survey lines allowed for QC.
