Flanking 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 m depth in  the ocean, the top sphere looks a lot dirtier than when it was deployed last August.  This “biofouling” can affect the measurements made by some of our instruments – one of the reasons they are replaced every year.  The instruments mounted closer to the seafloor come up a lot cleaner. Deck Lead Chris Basque and Instrument Lead Jennifer Batryn prepare to remove to instruments from the mooring riser – the wire ropes that connect the spheres at the top to the anchor at the bottom.
