Processed high resolution bathymetry acquired during the SERPENTINE, 2007 cruise of RV Pourquoi Pas?

High-resolution bathymetry data were acquired over three areas of the Mid-Atlantic Ridge, during three dives of ROV Victor 6000 SERPENTINE cruise onboard RV Pourquoi Pas?, using a RESON 7125 echosounder mounted on the ROV frame, with an operating frequencyof 400 kHz, a beam opening angle of 120°, a velocity of ~0.3 m/s, maintaining an altitude ~50 m above the seafloor and using ultra-short baseline ROV positioning. Data processing was conducted with the Caraibes 5.0 software (@Ifremer). The processed grids have a grid spacing of 0.5 m (Krasnov area), or 1m (Logatchev and Ashadze areas).
