Image Of the Day caption:
Large orange floats line the edge of the WHOI dock. In a couple of weeks, they'll board the R/V Neil Armstrong bound for the Pioneer Array, an ocean observatory about 100 miles south of the New England coast. These floats, known as "subsurface flotation spheres," are one component of a profiler mooring. A sphere is attached to the mooring's underwater cable to give it the buoyancy it needs to stay as vertical as possible. That in turn allows a sensor-laden device called a wire-following profiler to travel up and down the mooring cable, measuring temperature, salinity, oxygen, and other seawater characteristics.
