Drifter Buoys

The Institute for Computational Earth System Science (ICESS) utilizes Pacific Gyre GPS/ Mobitex™ "Microstar" drifters to observe and study near-shore ocean circulation off the Southern California coast. The drifters record their position with GPS every 10 minutes and transmit their position data in near real-time to a web-based host computer using the Mobitex narrow band, data-only, cellular communications system. This sort of time and space resolution enables characteristic near-shore circulation patterns to be properly resolved. The drifters give direct observations of paths taken by freely floating objects at the ocean surface such as spilled oil, other pollutants, or things lost at sea.
