A moored profiler is deployed from research vessel Oceanus
in the western subtropical North Atlantic for
climate change studies. Moored profilers take repeated measurements of ocean currents and water properties by traveling
up and down a subsurface mooring cable. It operates at depths of 50 meters (165
feet) down to the sea floor at 5,000 meters (3 miles) or more. The profiler
carries an acoustic current meter and an instrument to
measure temperature and salinity, and has the capability of carrying other instruments, such as
bio-optical and chemical sensors. This instrument and others involved in ocean observations will be on display at the Cambridge Science Festival at the MIT Museum, 265 Mass. Ave. Cambridge, Mass., on April 25, 2009. The event is free and open to the public.
