Note Imagery and 3D textured model of the Eiffel Towerhydrothermal Chimney at the Lucky Strike hydrothermal site (Mid-Atlantic Ridge). This structure is ~20 m high, and is found at ~1700 m water depth. Images, extracted from HD video and cropped to remove incrustations, have been processed with the Matisse software (ref Github to come) to generate a 3D textured model. This dataset is released as part of a publication by Arnaubec et al (submitted to Computers and Geosciences) and was analysed in Girard et al. (2020)

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).
