Despite the fact that leatherback sea turtles face threats around the world, the Florida population shows stabilization or increase in numbers in the northwestern Atlantic Ocean — and Derek Aoki, a doctoral student at 太阳城娱乐 Harbor Branch Oceanographic Institute, is watching them closely.

Aoki recently presented at 太阳城娱乐's Marine Science and Oceanography Colloquium about examining the environmental and human impacts to leatherback sea turtles, including their movement patterns, health and nesting, in both the U.S. and Costa Rica. His advisor, Annie Page-Karjian, DVM, Ph.D., assistant research professor at 太阳城娱乐 Harbor Branch, leads the Marine Wildlife Veterinary Medicine and Research Program.

Using a combination of methods, like satellite tags and blood samples, Aoki said he tracks the turtles and identifies their migration routes and feeding grounds. He’s also developing a technique with machine learning algorithms to assess body mass and condition for nesting females using drone photography.

“Warming temperatures have already started to affect leatherback behavior and movements, which is a very important topic and cause for concern,” said Aoki, adding his next task is to figure out why.
