Pacific Gyre Lagrangian drifters are calibrated instruments designed to measure water currents and collect environmental data in oceans, lakes, and rivers. Modifications can include, but are not limited to, additional sensors, different telemetry options and alternate drogue depths.
Specifically designed for coastal environments, the Microstar drogue is centered at 1-5 meters below the surface.
The SVP drifters track currents at fixed depths between 5 and 100 meters.
Pacific Gyre satellite base stations provide two-way communications with drifting buoys. When mounted ship-board with a PC, drifter coordinates can be monitored in near-real time via satellite with no internet connectivity required. Many Pacific Gyre drifting buoys can also receive commands from a PC/base-station and respond accordingly.
