We utilize Pacific Gyre GPS/
"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.
