In April, the Canadian research ship Coriolis II will set out from Halifax to survey parts of the continental shelf stretching 1,000 miles off the east coast of Nova Scotia.
The ship has been hired by Hibernia Atlantic, a Summit, New Jersey-based company that operates undersea telecom cables, to map out a new $300 million trans-Atlantic fiber-optic line called Project Express. The cable will stretch 3,000 miles beneath the North Atlantic, connecting financial markets in London and New York at record transmission speeds. A small group of U.S. and European high-speed trading firms will pay steep fees to use the cable.
