Flanking Mooring B Recovery
June 24, 2024
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 m depth in the ocean, the top sphere looks a lot dirtier than when it…

IRMINGER: It’s Pride Month and rainbows colors are everywhere out aboard the R/V Neil Armstrong!!
Surface Mooring Recovery
June 21, 2024
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, usually in a tangled heap called a “wuzzle”. The synthetic rope portion is pulled in…
OSNAP Moorings In
June 21, 2024
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 at the top. Cages with instruments are located at specific depths to measure different water…
Blue Whale Sighting
June 21, 2024
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 a variety of marine life including Dolphins, Fin and Humpback whales, and sea birds such…
Onto OSNAP
June 18, 2024
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) and water velocity sensors – are lined up in the main lab of the ship…
Anchor Away!
June 18, 2024
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, the full mooring is trailing behind the ship with just the anchor still sitting on…
Flanking Mooring B Next
June 17, 2024
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 mid-water release float, glass spheres and CTD instruments sit on the deck awaiting deployment. The…
Flanking Mooring A In
June 17, 2024
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 sphere which holds an ADCP instrument to measure water velocity. At the bottom of the…
