Multibeam backscatter data were collected with EM712 simultaneously with the multi beam bathymetry. Seapath 380 was used for positing and MRU corrections. DGPS correction was sent over the EMSAT and IOSAT L band beams with a FURGO subscription of 1 month. EMSAT is 1545.9275 Mhz (1200 bits per second bitrate) and the IOSAT is 1545.8075 Mhz (1200 bps bitrate)
Sound velocity profiles were acquired twice a day with a Valeport swift SVP with a maximum depth of 500m and extended up to 1200 using the SIS sound velocity editor. SIS 5 was used to collect multi beam data for all MBs with the same installation parameters. For 2040 we changed the roll correction to 0.105°
Multi beam data was processed as soon after the acquisition on board the vessel with the software Qimera. Multi beam data were processed as soon after the acquisition on board the vessel with the software Qimera. The applied corrections to the bathymetric data include sound velocity correction, cut of external beams and manual removal of spikes. The processed Dynamic surface was exported as .xyz, .arcascii and .Geotiff format at the following resolution: 5m from 0 to 150, 10 m from 150 to 600 and 20 m from 600 to 1200. The .kmall processed were exported to GSF and imported into FMGT software to run the backscatter mosaic. The mosaic obtained from EM712 was exported as .xyz, .arcascii and .Geotiff at a spatial resolution of 10 m. Navigation was exported for each MB line from Qimera as .txt file and converted to .shp file using global mapper. All data products were uploaded on the GISMAR-Cloud every day to be imported in the Jamme Gaia Geoportal implemented for the survey remotely.
