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.
Ocean Networks Canada’s first summer expedition aboard the CCGS John P. Tully returned to port with confirmation of a major discovery: an impressive plume of gas rising from the seafloor off Vancouver Island in a region monitored by the NEPTUNE observatory that has been discharging since at least 2010.
During the final leg of the month-long expedition in the Northeast Pacific Ocean, the vessel conducted sonar...
The evening of May 22, 2013 is fair and sunny. The seas are calm, and the atmosphere on board is cheerful. This afternoon, we finished the last tasks on the NEPTUNE Canada portion of the Ocean Networks Canada Installation and maintenance cruise. We are on the long transit back to Saanich Inlet to continue the last 2 days of work on the VENUS network. Thanks to the Tully crew and the ROV crew, along with all the cruise participants for making the operations a success!
Today marked the end of Leg 1 - servicing installations in the Salish Sea - wrapped up after a successful 10 days of operations. At 09:00 the newly arrived leg 2 crew stood in the sun on dock with the happy, but tired, leg 1 crew. We began loading our gear and instruments right away with the ship's crane and finished at 14:00. It took us until evening to rearrange it like a giant block puzzle and tie it all down. All those hours playing TETRIS finally paid off.
The CanPac ROV Team spent the day conducting maintenance on the Remotely Operated Vehicle and working through the various tooling required for leg 2.
In late April Ocean Networks Canada embarks on a series of maintenance cruises to service both the VENUS and NEPTUNE cabled observatories. Over the next 2 months, we’ll execute 3 of our 8 2013 expeditions, including two back-to-back cruises on the CCGS John P. Tully (April-May) servicing facilities first in the Salish Sea (VENUS) and then off-shore at Folger Passage and Barkley Canyon (NEPTUNE).
Following the Tully cruises in May, the deepest installations of ONC at Endeavour Ridge will be serviced by the R/V Thomas G. Thompson. Two science support expeditions in August and September on the R/V Falkor will precede our final maintenance cruise of 2013 in late October.
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.
During our adventures, we deployed 32 new instruments, including those...
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.
The JOIDES Resolution research drillship, a key vessel in the Integrated Ocean Drilling Program (IODP), was docked in Victoria this summer for three months of refit work before heading out on two cruises in July and September.
The Juan de Fuca Plate is a hot-spot of scientific ocean drilling. Since ODP expedition 139 in 1991, numerous boreholes have been drilled in the...
