Drifters

Drifters

We make our own in-house drifters to help understand ocean currents. These drifters use biodegradable sponges, cedar, a little bit of metal for stability, and on the top there is a SPOT GPS unit (commonly used by hikers) that transmits the location about every 5 minutes. Drifters typically last for about a month before the battery dies and breakdown of the materials begin.
