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…
Read MoreGlider Comparisons, Acoustic Checks, and a Successful Surface Mooring Deployment
The past two days aboard the R/V Roger Revelle have been productive. After wrapping up a met survey at SUMO-11, the team returned to the glider box for a 1200-meter CTD cast with the BGC pH sensor. The timing allowed for a clean comparison with glider data collected after their initial dives to 1000 meters.…
