A new study published in Scientific Reports reports the discovery of a remarkably extensive hydrothermal vent field on the shelf of Milos Island, Greece. The vents were identified during the METEOR expedition M192, where the research team used a combination of different methods, including underwater technologies such as an autonomous and a remotely operated vehicles, to survey the seafloor. These approaches revealed previously undocumented venting between 100 and 230 meters depth. This makes Milos home to one of the largest known shallow-to-intermediate hydrothermal systems in the Mediterranean and substantially expands current knowledge of vent distribution in the region.
