Satellite tracking reveals long-distance migrations of sea turtles

Satellite tracking technology is providing researchers with new insights into the migratory patterns of sea turtles across different regions.

In New Zealand, the Department of Conservation is tracking rehabilitated green turtles to understand their movements after release. One turtle, identified as 3K, traveled nearly 3,000 km in four months, visiting locations such as Rangaunu Harbour, Wellington, and Manukau Harbour. Researchers have noted that sheltered northern harbours with seagrass beds are particularly attractive feeding grounds for these animals.

In the Mediterranean, a loggerhead turtle named Lara traveled approximately 2,890 km from Cyprus to Tunisia over 127 days. After nesting at Lara Bay, the turtle moved through Cypriot, Egyptian, and Libyan waters before reaching the Boughrara lagoon near Djerba. This journey is part of a collaborative effort between the Mediterranean Turtle Research and Conservation Society and the US-based Sea Turtle Conservancy to map critical feeding and resting areas to better protect the species from threats like pollution and climate change.
