(The Gist of Science Reporter) Turtle Tracking Devices

All the marine turtles are well-known for their distant migration for breeding and feeding.
However, every year the population of turtles migrating to India Waters is decreasing.
A large number of breeding individuals die every year along the Indian coastline, and it has become a major concern.
To tackle this issue, turtle tracking or turtle tagging techniques have been used.
This technology uses satellite telemetry tags to protect sea turtles.
In this technique, a Platform Terminal Transmitter (PTT) is attached to the back of a sea turtle.
The PTT sends a signal to the satellite each time when the turtle surfaces for air.
The satellite re-transmits the data to a receiving station on earth.
In India the technique has been used in Chennai to make fishermen aware about the feeding grounds of turtles.
