The Stokes Drifter is a compact drifting buoy that tracks water currents at the surface. The small light-weight buoy is equipped with Iridium satellite telemetry, GPS positioning, and a sea surface temperature sensor. Iridium satellite telemetry enables the buoy to provide vital sensor and geo-positional location data in real-time.
Iridium also allows the buoy to have bi-directional capabilities. This is a critical ability, for example, if the buoy enters a region of interest the end-user can communicate with the unit by sending it a command to change reporting intervals or request essential time-sensitive data.
The applications for the Stokes Drifter are endless due to its compact size, however, the buoy is ideal for purposes ranging from mapping large-scale ocean currents, spill monitoring, environmental monitoring, and aiding in search and rescue operations.
