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.

Communications Complicated

Location of C/S Global Sentinal on marinetraffic.com map.

Recent damage to a commercial communications cable connecting Victoria and Vancouver has more impacts on Ocean Networks Canada than one might have thought! To start with, the repair, which will take several days to complete, will be performed by the only cable ship currently on the West Coast, the C/S Global Sentinel based in Portland, Oregon. It turns out that the same ship had been rented by Alcatel-Lucent Submarine Networks to complete their work on the NEPTUNE...

Cable Lays at Cascadia Basin

Cable laying is an important task at all of our locations – after all, we're building a cabled seafloor observatory. But it was especially important and challenging at our Cascadia Basin location, where we sought to install three 12.5km cables radiating out from the instrument platform to form an equilateral triangle with bottom pressure recorders at each corner. Such an array will be invaluable to researchers studying tsunamis in this region.

To accomplish these cable lays we used ROCLS, ROPOS's Remotely Operated Cable Laying System. ROCLS consists of a rugged aluminum frame that holds detachable cable drums. Individual cables are carefully spooled onto drums. Then, when it is time to deploy, they are fitted onto ROCLS. ROPOS is then attached to ROCLS and the two deployed...
