Rainbow massif (Middle Atlantic Ridge 36 14'N): AUV IdefX Microbathymetry and Acoustic Backscatter

Near-bottom multibeam bathymetry and acoustic backscatter acquired at the Rainbow Massif  (Mid-Atlantic Ridge). High-resolution bathymetry data (2 m/pixel) were acquired by the autonomous  underwater vehicle (AUV) IdefX, deployed during the ARC-EN-SUB (https://doi.org/10.17600/18000663)  cruise in May 2022. The dataset consists of grids for each individual AUV dive, as well as a global grid merging the ten completed dives. This global grid was obtained by manually shifting and combining original bathymetric grids of each dive using other datasets (primarily shipboard bathymetry from Paulatto et al. [2015]) for geographical reference. The combined grid shows the inter-dive shift artefacts, absent in the individual dive grids. Elevation grids are provided for each AUV dive without interpolation (fillgap 0), with medium (fillgap 3) and high (fillgap 15) interpolation.Acoustic backscatter grids are edited without interpolation (fillgap 0).

All grids are provided in NETCDF GMT .grd format, and with two associated GEOTIFFS with the bathymetry DEM, the acoustic backscatter, and the hillshade (illumination) file. 

All grids are given in WGS84 (WGS 84 - WGS84 - EPSG:4326), in projection Mercator.
