Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor "chimneys," and mineral particles in the fluids venting at the seafloor make the fluids look like smoke. These chimneys are at a vent site that scientists called "Roman Ruins," in the eastern Manus Basin in the Bismarck Sea south of the island of New Ireland in Papua New Guinea.
