In 2003 the Sea Turtle Conservancy began to study the migration patterns of critically endangered leatherback sea turtles (Dermochelys coriacea) nesting along the Caribbean coasts of Costa Rica and Panama. The study will reveal important information about the turtle’s migratory behavior, which will help both conservationists and natural resource managers to improve protection efforts for this endangered species.
The satellite transmitter attached to each leatherback sends signals to orbiting satellites each time the turtles surface to breath. The data will be collected and downloaded to STC researchers. Educational migration maps will show the best location points of the turtle’s movements and locations. This will allow interested persons all over the world to watch along as researchers discover where the giant leatherback turtles travel after nesting. Through STC’s Sea Turtle Migration-Tracking Education Program, the public is invited to watch along on the Internet as we learn more about these amazing animals.

Due to Covid-19 travel restrictions, STC was not able to deploy transmitters on leatherbacks from Panama or Costa Rica. For 2020, STC partnered with Florida Leatherbacks, Inc. to deploy transmitters on leatherbacks nesting in Florida.
