An unusual SONAR data plot was generated from COVIS (Cabled Observatory Vent Imaging Sonar) data on 20 May 2014, as the remotely operated vehicle ROPOS flew above Grotto hydrothermal vent in Main Endeavour Field (depth: 2195 m).
Ocean Network Canada’s Kim Juniper and Verena Tunnicliffe share their experiences studying the Endeavour hydrothermal vents in the April 19th Vancouver Sun article One of Earth’s Most Remarkable Places.
This story is the fifth of a six part special series on the "Health of the Ocean." The paper’s online publication has also compiled a photo gallery of this unique ecosystem located 250 km off Vancouver Island and over two km below the ocean’s surface.
