Deep-sea expedition to install tsunami antenna

摘要

The first NEPTUNE Canada ocean expedition of 2012 has cast off from Esquimalt aboard the 274ft. research vessel, Thomas G. Thompson. A major highlight of the month-long operations cruise is the installation of a deep-sea tsunami "antenna"—the first of its kind in the world. The star-shaped array of four ultra-sensitive bottom-pressure recorders will be positioned at the ends of new 25km arms of powered fiber optic cable, and will provide real-time data to Canadian scientists and the Pacific Tsunami Warning Network.
