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: It’s Pride Month and rainbows colors are everywhere out aboard the R/V Neil Armstrong!!  

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,…

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…

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,…

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…

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…

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…
