Eiffel Tower hydrothermal chimney (Lucky Srike ...

The Eiffel Tower active hydrothermal chimney is one of the main structures at the well-studied Lucky Strike hydrothermal field, along the northern Mid-Atlantic Ridge (37.3°N, 32.3°W). This chimney, raising ~20 m over the surrounding seafloor, is associated with black smoker fluids flowing at >300°C as well as diffusion areas colonized by large Bathymodiolus azoricus mussel beds and microbial mats. This vent edifice was surveyed by ROV Victor6000 using an HD camera. A first dataset including images extracted from the video were processed to remove ROV navigation incrustations (total of 4875). Part of these images are time-stamped and correlated with navigation, included in this dataset, and another sub-set was extracted from video lacking navigation. A second dataset includes 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).
