Multibeam bathymetry and backscatter processed data (Kongsberg EM 2040MKII working area dataset) of AUV HUGIN SUPERIOR during cruise with HANDIN TIDE in 2022, Hadarba Deep, Red Sea


This dataset contains a processed high-resolution (2m) bathymetry grid from the eastern axial volcanic ridge of Hadarba Deep. The acquisition was carried out in February 2022 from the OSS Handin Tide using the 6000m rated Hugin Superior AUV provided by FUGRO. The AUV was equipped with a Kongsberg EM2040 Mk2 multibeam echosounder set to 200 kHz. USBL navigation data were post-processed in NavLab. The bathymetry data were post-processed, merged with the corrected navigation, gridded, and interpolated in QPS Qimera. Multibeam backscatter data (0.8 m) were mosaiced in QPS FMGT from the raw data and cleaned Qimera GSF exports (both the bathymetric grid and backscatter mosaic are provided). All files' coordinate reference system (CRS) is EPSG:32637 - WGS 84 / UTM zone 37N.
