The researchers also used a WHOI-developed instrument called a Moored Profiler, a stout plastic pod housing temperature and salinity sensors and a current meter, deployed on a mooring that remains in the ocean for a year. The Profiler chugs up and down a mooring line by means of a tiny traction motor; it can collect hundreds of measurements throughout the water column and throughout the year.
