The Cabled Observatory Vent Imaging Sonar (COVIS) is a sonar system used to quantitatively image hydrothermal vents at the mid-ocean ridge. COVIS is installed at Main Endeavour Field on the Juan de Fuca Ridge, near Grotto and the North Tower hydrothermal vent fields. Hydrothermal fluids emitted by black smokers and diffuse flow from the surrounding seafloor is believed to transfer chemicals, heat and biological matter from the oceanic crust to the ocean. A time-series of 3-dimensional images, produced by COVIS, will help visualize the turbulent hydrothermal activity and processes occurring at mid-ocean ridges.
