This dataset inscludes shapefiles interpreted from photomosaics over the Milos shallow water hydrothermal system, and instrument locaitons, from fieldwork in July and September 2019. The shapefiles are organized by study areas (Agia Kyria, Paleochori, and Spathi bays). Details are provided in the associated paper (Puzenat et al., 2021) in addition to information in the Readme File associated. a) Shapefiles of seafloor textures interpreted from drone imagery. b) Shapefiles of seafloor texttures interpreted from AUV imagery. c) Shapefiles of instruments deployed in the study area in September 2019.

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.

The AMORGOS-23 cruise (https://doi.org/10.17600/18003211) was conducted onboard R/V Europe from April 26th 2023 to May 9th 2023. Using HROV Ariane equipped with 4K cameras, we surveyed the main active faults between Amorgos and Anafi islands in order to identify and quantify recent deformation of the seafloor linked to the 1956 Amorgos earthquake. During dive 244-1, we surveyed the steepest scarp of the Amorgos fault, along its central segment. We provide here seven scaled Digital Outcrop Models (in .obj format) calculated from the HROV videos with MATISSE 3D software. There location (model origin) is also provided in a table, together with information about the portions of the videos used to produce the models. Due to incomplete navigation data, the models are not properly oriented.

Milos Shallow Water Hydrothermal System: Drone seafloor photomosaics (July/September 2019 fieldwork)
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).
