OSNAP 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…
Read MoreBlue Whale Sighting
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)…
Read MoreAnchor Away!
IRMINGER: The moorings at the OOI Irminger Sea Array vary from 1.5 to 2 miles in length. To deploy them, the ship starts miles away from the target location and as it steams towards the target, we build the mooring off the stern of the ship. By the time ship arrives at the target location,…
Read MoreFlanking Mooring B Next
IRMINGER: The second Flanking Mooring was deployed at the OOI Irminger Sea Array; the last of the 4 new OOI moorings to be deployed. Flanking Mooring B is just like Flanking Mooring A deployed the day before. The top sphere can be seen trailing behind the ship during the deployment. Other components such as the…
Read MoreFlanking Mooring A In
IRMINGER: The OOI-CGSN team deployed Flanking Mooring A in the OOI Irminger Sea Array off the tip of Greenland. The Flanking Moorings consist of a top floatation sphere which sits at 30 m water depth. Instrumentation is mounted in the sphere and along the mooring line below it. At 500 m depth is another mid-water…
Read MoreHands-On Experience for POGO Fellow
STATION PAPA: POGO Fellow Aditi Sharma is on the return leg to Seward, Alaska, having spent the last 15 days aboard the R/V Sikuliaq learning the ropes of an OOI recovery and deployment expedition. She also has been collecting data using a sea-snake boom that she and OOI Principal Investigator Jim Edson deployed. The sea…
Read MoreGlider Ops
IRMINGER: In addition to fixed moorings, the OOI Irminger Sea Array consists of autonomous gliders. Two gliders were deployed to the array for a one year deployment, and one glider deployed last year was recovered. The gliders sit on the back deck prior to deployment so that the glider team on shore can communicate with…
Read MoreProfiler Mooring in the Water
IRMINGER: Another gray day in the Irminger Sea and another OOI mooring in the water. The Profiler Mooring consists of a top sphere at 150 m with upward- and downward looking bioacoustic sonar instruments, and a profiler which crawls up and down through the water column measuring conductivity, temperature & depth, dissolved oxygen, fluorescence and…
Read MoreHybrid Profiler Mooring Recovered
STATION PAPA: The Station Papa moorings are replaced on a yearly schedule. Here the OOI-CGSN team recovers the Hybrid Profiler Mooring. The yellow vehicle seen on the mooring wire is a Wire-Following Profiler (WFP). The vehicle moves up and down the wire sampling the water column for salinity, temperature, pressure, dissolved oxygen, chlorophyll, and current…
