Profiler 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 water velocity.  After spooling out the long shot of wire rope for the profiler to crawl along, the deck team puts a Yale grip on it to hold the load while they connect it to the next mooring component.
