The Irminger Global Surface Mooring recently recorded a unique view – the R/V Revelle departing from the array site. Captured by the mooring’s camera system, the image provides a rare perspective of ship operations from the vantage point of the mooring itself.

The Irminger #12 team never stops. On the transit back to Reykjavik, with all field deployments and recoveries successfully completed, the OOI Coastal and Global Scale Nodes (CGSN) team turned to the next task: dismantling the Global Surface Mooring. This work prepares the mooring for offload upon arrival and shipment back to Woods Hole Oceanographic…

During the Irminger 12 expedition, the team spotted a group of curious pilot whales near the Irminger Array. The whales approached the area during operations, providing a brief and welcome encounter for those on board. Such sightings add to the experience of working at sea and offer a reminder of the diverse marine life that…

The Irminger #12 team has completed its final mooring operation: the recovery of the Global Surface Mooring. This is the largest mooring built and deployed by the OOI Coastal and Global Scale Nodes (CGSN) team. A new Global Surface Mooring was deployed at the start of the cruise, and the recovery of the previous mooring…

While the primary focus of the OOI Irminger 12 cruise is deploying and servicing moorings in the North Atlantic, life at sea involves much more than operations on deck. When weather conditions temporarily halted work, members of the Coastal and Global Scale Nodes (CGSN) team made the most of their downtime — gathering around the…

The process of deploying a surface mooring is a precise operation that starts at the ocean’s surface and ends 2,700 meters below on the seafloor. Two new videos from the R/V Revelle capture key moments in this deployment process. Part 1: Buoy DeploymentThe surface buoy is towed slowly behind the ship, trailing more than 3…

The Coastal and Global Scale Nodes (CGSN) team (Jim Ryder, Kris Newhall, James Kuo, Dan Bogorff, and Nikki Arm) have successfully re-deployed the Hybrid Profiler Mooring (HYPM) in the Irminger Sea. Following its recent servicing, the HYPM and its Wire-Following Profiler will resume sampling nearly 2,400 meters of the water column, providing critical oceanographic data…

Following the recovery of the Hybrid Profiler Mooring (HYPM), the CGSN team conducted a full inspection of the system. All components were checked, with any old or damaged parts refurbished or replaced, before the entire mooring was rebuilt. This marks the first time the HYPM and its profiling vehicle have been serviced entirely at sea.…

The OOI Coastal and Global Scale Nodes (CGSN) team has successfully deployed the Global Surface Mooring (GSM) as part of the ongoing Irminger Sea Array operations. The GSM is equipped with a suite of meteorological, oceanographic, and biological sensors, designed to collect continuous data from the atmosphere, ocean surface, and throughout the water column. This…

The Coastal and Global Scale Nodes (CGSN) team has officially arrived at the Irminger Array, marking a major milestone in this year’s field season. First up on the operational checklist? Glider deployment. Two autonomous underwater gliders were successfully launched and are now running in a holding pattern near the array. These sleek, torpedo-shaped robots are…
