The Eiffel Tower active hydrothermal chimney is a major edifice investigated in deep-sea vent ecology at the Lucky Strike hydrothermal field (~ -1700 m), along the northern Mid-Atlantic Ridge (37.3°N, 32.3°W). This edifice, 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 assemblages and microbial mats. This vent edifice was surveyed with vertical overlapping transects by ROV Victor6000 using an HD camera during the MoMARSAT2020 cruise. This dataset is part of a larger temporal series performed with other 3D reconstructions at the Eiffel Tower hydrothermal edifice that was used to investigate temporal dynamics of the edifice topography and the vent assemblages (Van Audenhaege et al. in prep.; see section "Note").
