Canada's New Observatory Uses 'Seafloor GPS'

hazards is to be deployed offshore Vancouver, Canada, using long endurance acoustic sensing technology supplied by Sonardyne International Ltd.The new Northern Cascadia Subduction Zone Observatory (NCSZO) will use a “seafloor GPS” network to monitor long-term movements of the subducting Juan de Fuca plate and overriding North American tectonic plate. Data gathered by the new observatory will play a critical role in informing assessments of earthquake and tsunami risk to the large populations of the Pacific North-West.The NCSZO is led by Ocean Networks Canada (ONC)—an initiative of the

In addition, WHOI will serve as the home of a new OOI Project Management Office

MBARI ROV Doc Ricketts Makes 1,000th Dive

Research Institute (MBARI) remotely operated vehicle (ROV) Doc Ricketts completed its 1,000th dive on December 21, 2017, marking a significant milestone for the vehicle and its team of pilots. Since it began operations in February 2009, Doc Ricketts has explored the deep sea as far north as the Juan de Fuca Ridge off the Pacific Northwest coast and as far south as Baja California, Mexico.   The ROV’s milestone dive could not have taken place in a more picturesque place. MBARI researchers and scientists from the Monterey Bay National Marine Sanctuary were revisiting an area called Sur

fleet in 1888, the Boyden quickly made a name for herself as a powerful and capable tug, transporting coal, coke and lumber between ports on Vancouver Island and Puget Sound. The J.E. Boyden was also involved for many years as a tug for sailing ships entering the variable waters of the Strait of Juan de Fuca and Puget Sound, and assisted in the salvage efforts of the 256-foot British iron ship Kilbrannan for several months in the spring of 1896. Scuttled in 1935 in 40 feet of water in Lake Union, the J.E. Boyden wreck is still well preserved and its integrity and orientation have been documented using

taken her out into open water yet.”   Then a crowd of well-wishers from town (including one Halloween Frankenstein), who had come to think of Neil Armstrong and its crew as their neighbors, slipped our lines from the dock and we were away. Come what may, our bow pointed down the Strait of Juan de Fuca to the open ocean.   The first vague idea of what would become Neil Armstrong took shape in the 1990s, when the U.S. Navy began to lay the groundwork to replace some the largest Global Class research ships, which were well into their third decade of service at the time. In 2002, the Navy

Canada Installs Radar to Detect Tsunamis

. Ocean Networks Canada is funded by the Government of Canada and includes a partnership with IBM Canada.    Similar to the disastrous March 2011 Tohoku-Oki earthquake, the west coast of British Columbia has the potential for very large earthquakes to occur along the boundaries of the Juan de Fuca tectonic plate. It is anticipated that the radar will be able to detect the surface expressions of tsunamis up to 100 km from shore, which will provide twenty to thirty minutes of advance warning.

Kvichak to Build 48 ft. Foil Research Cat

Kvichak Marine Industries, a Vigor Company, was recently awarded a contract to design and build a 48’ all-aluminum foil assisted research catamaran for the King County Environmental Laboratory.  The vessel will operate in Puget Sound, the Straits of Juan de Fuca and adjoining inland waterways.  The vessel will be conducting water sampling research along with marine buoy calibration, maintenance and retrieval, tours and shoreline surveys, dive and ROV operations. This will be the thirteenth foil assisted catamaran Kvichak has built since 2000. Kvichak’s unique foil design

Shell Arctic Rig Protesters Detained and Released

Police Department, King County Sheriff's Office, Seattle Fire Department and Washington State Patrol were involved in the enforcement of the 500-yard safety zone.   The USCG said its assets will continue to enforce the safety zone around the Polar Pioneer's transit north into the Strait of Juan de Fuca.  Planned protest activity is expected along the way, and the USCG will continue to manage waterway safety specifically commercial traffic within the shipping lanes.   On April 28, the Coast Guard established 100-yard safety zones around Arctic drilling and support vessels while moored

The ship will then leave Newport, Ore., to work on a 200-mile horseshoe-shaped cable off Oregon’s coast, where the Juan de Fuca plate dives under the continental plate to create the Pacific Northwest’s number-one earthquake threat. As well as one day monitoring seismic activity, researchers at the UW and Oregon State University will track currents bringing nutrients from the deep ocean up to the continental shelf
