3288_Mineplat_HR_C - Alentejo shelf - folded structures & sorted bedforms- 4m res.
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.

- 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.
