Multibeam bathymetry processed data (Kongsberg EM 2040MKII working area dataset) of AUV HUGIN SUPERIOR during cruise with HANDIN TIDE in 2022, Hatiba Mons volcano, Red Sea@en

This zip file contains a processed high-resolution (2m) bathymetry grid from the summit of the Hatiba Mons volcano in the Red Sea rift. The data were collected in February 2022 with a 6000m rated Hugin Superior AUV provided by FUGRO. The AUV carried 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 (1m) were mosaiced in QPS FMGT from the raw data and cleaned Qimera GSF exports (both mosaics are provided). All files' coordinate reference system (CRS) is EPSG:32637 - WGS 84 / UTM zone 37N.
