From seafloor to surface

A surface buoy bobs in the rough water of the Northwest Atlantic near the Gulf Stream. The buoy, one of many deployed in late 2005 as part of the CLIMODE (CLIvar MOde water Dynamics Experiment) program, is equipped with meteorological instruments, as well as sensors extending to the seafloor miles below to record temperature, current speed and direction, pressure and other ocean conditions. CLIMODE is a five-year program to study the transfer of energy from deep waters to surface waters and its effect on climate.
