June 4, 2025
The Spring 2025 Coastal Endurance Array Turn Cruise (SR2511) has officially concluded. On the evening of May 29, the R/V Sally Ride docked at OSU Ship Operations in Newport around 21:30 PDT, marking the end of a successful three-leg expedition. Final recovery operations included: Oregon Shelf Coastal Surface Piercing Profiler (CE02SHSP-00039) WireWalker profiler Oregon Shelf Surface Mooring (CE02SHSM-00019) With all scheduled recoveries and deployments complete, offloading is planned for May…
Cruise Update – SKQ202511S (May 29-30)
May 30, 2025
The final two days of Cruise #SKQ202511S wrapped up with successful recoveries and smooth operations. On May 29, the team conducted a 4,100m CTD cast and acoustic data download at site FLMA-11. All instruments were operational. This was followed by the final OOI mooring recovery at the same site, completed without issue. While transiting to the next location, the crew off-spooled the TSE winch and conducted a visual check on…
From the Deep: HYPM Recovery Complete
May 29, 2025
After spending a full year in the depths of the ocean, the Hybrid Profiler Mooring (HYPM) has been successfully recovered by the CGSN team aboard the RV Sikuliaq. Using an acoustic release command, the team triggered the mooring to detach from its anchor and ascend to the surface. What came up: the bright orange syntactic sphere, riser components, profiling vehicle, instrument packages, and recovery buoyancy—all intact and secured on deck….
Profiler Recovery and Troubleshooting
May 29, 2025
As Leg 3 of the Spring 2025 Coastal Endurance Turn Cruise (SR2511) continues, the R/V Sally Ride team successfully recovered the Washington Inshore Coastal Surface Piercing Profiler (CE06ISSP-00019). The crew also troubleshooted the Washington Offshore Profiler Mooring (CE04OSPM-00022) to assess and address operational issues. The team worked in 5–7-foot seas, with air temperatures between 52–55°F and winds ranging from 10 to 20 knots, under partly cloudy skies. Despite dynamic conditions,…
Cruise Update – SKQ202511S (May 27-28)
May 28, 2025
Tuesday, May 27:Calm seas made for ideal conditions to begin early morning prep for the FLMB-12 mooring deployment. The mooring was rigged, instruments mounted, and the 64” upper sphere placed between the A-frame. Following a GAR check, deployment went smoothly just after breakfast. After safely moving off-site, the team conducted a full-depth 4,100m CTD cast, followed by an anchor survey and an afternoon of Rosette water sampling and processing. Wednesday,…
Oregon Offshore Mooring Swap
May 28, 2025
As part of Leg 3 of the Spring 2025 Coastal Endurance Turn Cruise (SR2511), the team aboard the R/V Sally Ride completed a successful mooring swap at the Oregon Offshore site. The new surface mooring (CE04OSSM-00019) was deployed, followed by the recovery of the previous mooring (CE04OSSM-00018). These moorings are key to monitoring offshore ocean conditions, contributing valuable long-term data on temperature, salinity, currents, and more. The team worked through…
A Year Below the Surface: HYPM Deployment at the Papa Array
May 27, 2025
Better than a racecar pit crew? We’d say yes. On land, pit crews get another shot when the car comes back around. At sea, when our equipment goes overboard, it’s out of sight for an entire year—no second chances. That’s what makes precise coordination and timing so essential during deployments like this one aboard the R/V Sikuliaq. During the recent Papa cruise, the team successfully deployed the Hybrid Profiler Mooring…
Successful Deployment at Sea: NOAA-PMEL and OOI-CGSN Team Up at the Papa Array
May 27, 2025
The R/V Sikuliaq recently completed the successful deployment of a NOAA-PMEL surface mooring at the OOI Papa Array—a key milestone in technical collaboration between NOAA-PMEL and the OOI Coastal and Global Scale Nodes (CGSN) team. As part of a joint turn cruise, an OOI FDCHP (direct covariance flux sensor) was deployed on the mooring for the first time. This test run is already transmitting wind, temperature, and motion data via…
Oregon Shelf Deployments and Surveys
May 27, 2025
The Spring 2025 Coastal Endurance Turn Cruise (SR2511) is now in its third and final leg, with operations resuming after departure from Newport, Oregon. The team aboard the R/V Sally Ride successfully deployed the Oregon Shelf Surface Mooring (CE02SHSM-00020) and the Oregon Shelf Surface Piercing Profiler (CE02SHSP-00039)—key components for monitoring coastal ocean conditions. Additional activities included a test deployment of the WireWalker profiler and an EK80 bioacoustic survey around the…
Leg 2 Complete: Oregon Inshore Recovery and Return to Newport
May 26, 2025
The R/V Sally Ride has completed its transit south to Oregon as part of the Spring 2025 Coastal Endurance Turn Cruise (SR2511). Before heading into port, the team successfully recovered the Oregon Inshore Low Power Surface Mooring (CE01ISSM-00021)—retrieving valuable ocean data from the past deployment cycle. With recovery complete, the ship docked in Newport, marking the end of offshore operations for this leg of the cruise.
