Moored profiler retrieval

Understanding the Warming Arctic

WHOI mooring technician Jim Ryder (center) and members of the crew aboard the R/V Lance work to remove an instrument that measures temperature and salinity from the mooring wire during an expedition in the high Arctic. Scientists onboard are studying how the polar ocean circulates and, in particular, the fate of warm Atlantic water flowing north into the Arctic Ocean. A moored profiler is used to make repeated measurements of water properties across a long section of the water column. The instrument on the wire had been profiling 1,000 meters of water every 12 hours for an entire year. Join the expedition online where researchers are posting daily updates.
