drifting buoy

A drifter that is fixed to a buoy that can be tracked by satellite, radio, or other means.

Surface and subsurface drifting buoys can obtain measurements of hydrographic (e.g., temperature) and chemical (e.g., fluorometry) parameters in addition to providing position information that is used to calculate currents. Surface and subsurface drogues can provide information on the currents at any chosen depth or density horizon.
