Irminger 11
And It’s Done
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…

Read MoreFlanking Mooring B Recovery
IRMINGER: After deploying all of the “new” moorings, the CGSN team is now recovering the “old” ones. Dan Bogorff hooks into the mid-water sphere from Flanking Mooring B. Having both moorings in the water at the same time (~1 week) allows the team to get data from both for comparison. After 1 year at 30…

Read MoreSurface Mooring Recovery
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…
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…
