High-resolution bathymetry map (15-m grid) of a segment of the SWIR provided by MBES data acquired during the 2021 SWINGS marine expedition on the Marion Dufresne vessel
A MBES acoustic coverage of the PE-1 segment of the SWIR (South West Indian Ridge), more specifically in the vicinity of the dredge 5 location of the SWIFT cruise (2001), was carried out during the SWINGS cruise (https://doi.org/10.17600/18001925) with the French research vessel Marion Dufresne in 2021. SWINGS data were acquired with the hull-mounted multibeam echosounder Kongsberg EM122 12 kHz using an optimised configuration for bathymetry data collection: vessel speed of 5 knots, dual swath, CW signal and an angular opening of 120°. Acoustic data were processed with GLOBE software (https://doi.org/10.17882/70460) to provide a high-resolution bathymetry map (grid resolution of 15 m).
