VISIONS' 14 Expedition
Completing the construction of the Regional Scale Nodes cabled ocean observatory
For just over 12 weeks, we were out at sea on-board the R/V Thomas G. Thompson with the University of Washington (UW) for the VISIONS '14 expedition which ran from the 13th of July to October 6th, 2014. For the third year, our role was to install the secondary infrastructure of the OOI Regional Scale Nodes cabled ocean observatory with the UW Ocean Observatory Initiative (OOI) team of oceanographers and engineers. On all fronts, this expedition was a resounding success which marked the transition between RSN's construction to its operation and maintenance. As always, CSSF and its staff enjoyed the many challenges brought forward by this ambitious project.
ROPOS’ first expedition of the year was in support of L3 MariPro onboard the C/S Dependable. The primary objective of this expedition was for ROPOS to assist in the recovery and repair of a Primary Science Node that will be used by the Regional Scale Nodes program.
The ROPOS team completed a short but very busy expedition onboard the CCGS John P. Tully for Ocean Networks Canada (ONC). The expedition, named Wiring the Abyss 2014, focused on the maintenance of ONC’s deepest Northeast Pacific observatories: Endeavour (2300m), Clayoquot Slope (1250m), and Cascadia Basin (2660m).
As with all good things the OOI/RSN/UW Visions’ 13 expedition has now come to an end. This challenging cabled observatory expedition went very well and some highlights of the expedition included:
- Over 22,000m of fibre optic extension cables on seafloor – all tested and functional.
- Three medium powered junction boxes – all tested and functional.
- Four short-period seismometers at Axial – all tested and functional.
- And many more…
