Samuel Wantman adds: "As each turtle emerges from its shell, it climbs up to join its siblings at the top of the clutch of eggs, creating a wave of commotion among all the other baby turtles in the nest. We can use the system to detect hatching and to better predict when the hatchlings will emerge onto the beach." The TurtleSense system is a low-cost, creative solution that remotely allows us to detect how baby turtles synchronize developmental movement within the nest in real time. ![]() While this study focused on Loggerhead turtles, the researchers also monitored Olive Ridley and Green Turtle nests and saw similar patterns, suggesting that the system will work for a range of sea turtle species.Įrin Clabough adds: "It's absolutely magical to witness baby turtles poke their heads out of the sand and sprint towards the ocean, but it's an event that can be very hard to predict. The system can also shorten beach closures and enable communities to engage in turtle-based ecotourism, benefiting both the community and sea turtle conservation efforts. The new TurtleSense system has the potential to reduce the cost and labor required to monitor endangered turtle nests and to help conservationists make better decisions about nest management. The system also accurately identified non-viable nests where monitoring was no longer necessary. Their results suggest that hatchlings can detect motion, which allows them to communicate and head out together as a group. The researchers identified a pattern of intense hatchling movement within the nest, followed by a pause, which let them predict almost the exact day when the young turtles would dig out of the sand. They buried an egg-sized sensor within the nest and attached a cable to a communication tower that remotely transmitted data on the movement of hatchlings within the nest. In the current study, researchers used the TurtleSense system to monitor loggerhead sea turtle nests on Cape Hatteras National Seashore to see if they could predict more accurately when the turtles would emerge from the nest. Conservationists can count the days since eggs were laid to predict when they will hatch and then watch the nest, but these efforts are inaccurate and labor-intensive. ![]() Sea turtle conservation efforts largely focus on protecting vulnerable hatchlings once they emerge, to ensure they head out to sea, instead of toward the bright lights of towns. Sea turtle populations worldwide are in decline due to human activities, with Loggerhead, Green, Hawksbill, Kemp's Ridley, Leatherback and Olive Ridley sea turtles all listed as threatened species.
