OOI Team Recovers UK BGC-Argo Float During Transit
During transit to the Irminger Array, the crew of the R/V Revelle and the OOI Coastal and Global Scale Nodes (CGSN) team successfully recovered a BGC-Argo float on behalf of the UK National Oceanography Centre (UK NOC). The float, deployed in 2024, had been collecting biogeochemical profiles focused on the biological carbon pump, along with…
Read MoreHybrid Profiler Mooring Recovered, Ready for Another Year of Ocean Observations
The OOI Coastal and Global Scale Nodes (CGSN) team recently completed the recovery of the Hybrid Profiler Mooring (HYPM) during the Irminger #12 cruise. The HYPM plays a key role in collecting and transmitting oceanographic data from the Irminger Sea. The mooring is equipped with a profiling vehicle that travels up and down the mooring…

The R/V Roger Revelle departed Reykjavík on July 18 after several days of mobilization and gear loading, including reassembly and testing of the Surface and HYPM moorings. With the surface buoy secured and burn-in restarted, final checks were completed and the team got underway. Transit to the array site (July 18-20) was smooth, with calm…

IRMINGER: Mooring operations have been completed at the OOI Irminger Sea Array with the recovery of Flanking Mooring A. The top sphere was in good shape, but a little dirty after its year-long deployment. John Jordan hooked a recovery line onto the sphere to bring it aboard. The glass balls and acoustic releases at the…

IRMINGER: The weather toyed with the CGSN team the day of the Surface Mooring recovery – varying between sun and fog. Surface Mooring recovery is essentially the reverse of deployment. The anchor is released and the glass balls at the bottom of the mooring float up to the surface. The glass balls are recovered first,…
Read MoreOSNAP Moorings In
IRMINGER: The Overturning the in the Subpolar North Atlantic Program (OSNAP) has a line of moorings on either side of the OOI array. Those moorings are being recovered and re-deployed with new instrumentation. One mooring has a subsurface sphere which needed to be cleaned prior to redeployment. Other moorings have glass balls to provide buoyancy…

IRMINGER: While the OOI and OSNAP teams are busy with mooring operations, Pete Duley from NOAA is busy looking for marine mammals. Big eye binoculars mounted on the bow of the ship, give him a great vantage point to scan the seas. His primary goal is to observe Right Whales, but he has been spotting…
Read MoreOnto OSNAP
IRMINGER: All four of the new OOI Irminger Sea moorings have been deployed and the deck is looking a lot emptier than when we departed Woods Hole 2 weeks ago. Now we will transition to mooring operations for the Overturning in the Subpolar North Atlantic Program (ONSAP). Their instruments – conductivity, temperature & depth (CTD)…
