Submarine fault scarp and traces of earthquake (Roseau Fault, French Antilles): 3D scene and imagery

Fault scarp along the Roseau normal fault between Les Saintes and Dominica (French Antilles), at a water depth of 1100 m. This fault scarp is sub-vertical and at its base displays a marker that corresponds to the exposed fault plane during the 2004 Les Saintes Earthquake. The model shows here a coseismic displacement of ~1 m. This scarp was one of several surveyed along the Roseau Fault rupture during the Subsaintes cruise (https://doi.org/10.17600/17001000), with ROV Victor 6000 equipped with an HD Video camera. Two datasets are provided. First, the survey imagery, with a video (mp4 format) and an associated navigation file in txt format. Second, a 3D textured model of the site (obj format), together with the a kml file for georeferencing, and a geotiff orthomosaic. This dataset is one of several sets released with a paper by Arnaubec et al. (submitted March 2021, Computer and Geosciences) presenting the Matisse image processing software, and the 3DMetrics Visualization and analysis software (ref Github to come).
