Wiring the Abyss Leg 2: 23 July – 3 August 2018

In July 2018, a team of 48 scientists, engineers, communicators, and crew aboard the exploration vessel Nautilus conducted around-the-clock operations to maintain and expand instrumentation on Ocean Networks Canada’s cabled observing systems off Canada’s west coast.

Highlights include an exciting new neutrino experiment at Cascadia Basin to determine whether this location can support a large-scale neutrino detector array in the future; expanded instrumentation at Endeavour, including new sensors and cameras to improve our understanding of this dynamic hydrothermal vent ecosystem; installation of the final earthquake early warning seafloor sensors at Cascadia Basin, Barkley Canyon, and Clayoquot...

Thompson Expedition Summary: June 2013

​

​

We are back in the office after nearly 3 weeks at sea aboard the University of Washington’s R/V Thompson. The team followed the Operations Plan that was set out over the last 6 months and achieved most of the planned goals. The weather co-operated perfectly for dive operations, resulting in no weather downtime. The remotely operated vehicle (ROV) crew ensured that there was as little vehicle downtime as possible and was quick to resolve any problems subsea and on deck.

Oaxaca Earthquake Sensed by ONC CORKs

A magnitude 7.4 earthquake struck the state of Oaxaca, Mexico at 12:02 local time, 20 March 2012. This region is above a tectonic plate boundary where the Cocos Plate is being subducted below the North American Plate at a rate of 6.4 cm/yr. Moderate to very strong shaking was experienced throughout an area within 100km of the epicenter.

24 minutes later, the seafloor pressure sensor on CORK 1026B at our Cascadia Basin (formerly ODP 1027) location sensed the pressure waves as they propagated through the earth. This trace shows these observations:

Piezometer Installation

R/V Thompson in front of the Olympic Mountains.

Scientists from Canada and France began deploying a cabled piezometer at 9:45 am (PDT) on Wednesday, July 6, 2011 at the Cascadia Basin site. This is the first operation of the NEPTUNE Canada July 2011 installation and maintenance expedition on the R/V Thompson. In visible company was the R/V Atlantis, the sister ship of the R/V Thompson, with a crew of researchers working on nearby Ocean Drilling Program (ODP) boreholes, an illustration of the high interest in the thin oceanic crust of the Juan de Fuca tectonic plate.

The needle-like probe...

September 2011 Expedition Complete

Our fall 2011 installation and maintenance expedition sailed September 10 – 30 aboard the R/V Thompson. It was a very active time for 7 Ocean Networks Canada staffers, 4 contractors, 1 Pacific Geosciences Centre technician, 1 volunteer, an 8-man ROPOS crew, 2 marine techs and the 21 crew members of the R/V Thompson. During our 20 days at sea, we completed 13 ROPOS dives at three locations, including a trip into Bamfield for parts.

Our itinerary during the September 2011 cruise.

During our adventures, we deployed 32 new instruments, including those attached to a Regional Circulation Mooring, retrieved-refurbished-...

July 2011 Expedition Comes to an End!

From July 4 - 25, 2011, Ocean Networks Canada navigated an impressive installation and maintenance expedition in the northeast Pacific Ocean. Diving down to the seafloor to investigate our 800-km cabled network observatory along the northern Juan de Fuca plate, we tended to our technically-advanced instruments and witnessed some of the amazing marine life dwelling off the coast of Vancouver Island, British Columbia.

May 2010 Cruise Recap

​

​

​

Our Spring 2010 installation & maintenance cruise sailed May 8-24 aboard the CCGS John P Tully. It was a very busy time for 4 Ocean Networks Canada staffers, 2 contractors, 1 student and 1 Canadian Navy officer who joined 8 ROPOS crew members and the 21-member CCGS Tully roster. In the space of 16 days we completed 21 ROPOS dives at 5 locations, including one dive to the Fraser Delta site in the Strait of Georgia.

Samoan Tsunami Detected

When a devastating magnitude 8.0 earthquake occurred roughly 200 km south of the Samoan Islands at 17:48:11 UTC on Tuesday September 29, 2009, it generated a trans-oceanic tsunami that spread at jet-like speeds throughout the Pacific Ocean.

At 04:57:33 UTC on 30 September, roughly 11 hours after the earthquake, five of our newly deployed Bottom Pressure Recorders (BPRs) and one...
