AUV photomosaics of the seafloor at the shallow-water Milos hydrothermal system. Photomosaics were acquired with the Sparus II (Iqua, Girona) AUV and constructed from vertically acquired still images. Images were acquired in July 2019 at the Paleochori and Spathi Bays. Photomosaics are provided as geotiffs (UTM Zone 35). This dataset includes both original photomosaics, that show distortions due to AUV navigation drift, and georeferenced photomosaics, that have been registered with the associated drone photomosaics at these same areas.

Colour seafloor photomosaics along towed camera tracks crossing the axis of the Lucky Strike ridge segment (Mid Altantic Ridge).  Images were acquired with the WHOI TowCam system (https://www.whoi.edu/what-we-do/explore/underwater-vehicles/towed-vehicles/towcam/), during the Graviluck 2016 cruise.  Images are process for colour and illumination correction. Images are placed and photomosaiced based on USBL navigation of the TowCam, altitude, and orientation.  The datasets include geotiffs for each of the tracks. To be cited: cited: Gini et al.

Black and white seafloor photomosaic of the Lucky Strike hydrothermal field and the ridge axis to the South, acquired with VICTOR6000 during the Bathyluck 2009. Individual still images were matched, corrected for uneven illumination, renavigated and blended for a seamless photomosaic.  This data release includes partial geotiffs covering the whole surveyed area.

Abstract Torpedo boat wreck off-the southern French Mediterranean coast (43.124°N;6.523°E), at a water depth of ~476 m. This battle ship sank in 1903 (https://www.postenavalemilitaire.com/t11913-torpilleur-059-1881-1903) and the wreck is is ~20 m long and 3 m wide, raising ~2 m above the surrounding seafloor. This shipwreck was surveyed using the HROV Arianne in 2016, deployed from N/O L’Europe, and equipped with a vertical electronic still camera. Two datasets are provided. First, the survey imagery, that consists of 442 images (jpeg format) and an associated navigation file in dim2 format (torpdo_boat_imagery). Second, a 3D textured model of the site (obj format), together with the a kml file for georeferencing, and a geotiff orthomosaic (torpedo_boat_model). This dataset is one of several sets released with a paper by Arnaubec et al. (submitted to Computer and Geosciences) presenting the Matisse image processing software, and the 3DMetrics Visualization and analysis software (ref Github to come). Arnaubec, A., J. Escartín, J.

Drone photomosaics of the seafloor at the shallow-water Milos hydrothermal system. Photomosaics were acquired with a Phantom and a Mavic Pro drone. Images were acquired in July and September 2019. Photomosaics are provided as geotiffs (UTM Zone 35).
