Sintra edifice (Lucky Srike Hydrothermal Field, Mid Atlantic Ridge) 2023: 3D textured model and imagery
The Sintra hydrothermal vent site reconstructed in this dataset is 311.82 m². It is located in the North east of the main Lucky Strike Hydrothermal Vent Field (LSHF). The edifice has been surveyed with the remotely operated vehicle Victor6000 for inter-annual monitoring during the 2023 Momarsat cruise. Video transects were collected during dive 844-6 with a forward-looking camera and video sequences were used to build a 3D model of the edifice using structure-from-motion techniques. A first dataset includes 1561 images extracted every 2 seconds from the videos. The images are time-stamped and linked to a navigation file, which is generated by interpolating navigation data at the corresponding timestamps. A second dataset includes a 3D textured model of the site (obj format) together with the a kml file for georeferencing. The ROV navigation file (.txt) is provided separately.
