Completion of NEPTUNE Canada

Canada has just made scientific and technological history, completing the installation of NEPTUNE Canada—the world’s largest and most advanced cabled ocean observatory. Most of the 4-week voyage aboard RV T.G.Thompson was spent at volcanically active Endeavour Ridge, where the team installed two six-kilometre cables and 29 instruments on the seafloor and connected them to the main NEPTUNE Canada network.

Every year for the next 25 years, NEPTUNE Canada will amass more than 60 terabytes of scientific data—equivalent to the text in about 60 million books—on biological, physical, chemical and geological processes in the Pacific Ocean.
