The leatherback sea turtle population in the Pacific, once the species' stronghold, has decreased by over 90% since 1980. Help scientists investigate this decline and find ways to save this and other sea turtle species.
Researchers must understand all aspects of sea turtles’ lives to ensure their protection, including migration routes and nesting success. As part of this effort, you will patrol the beach after dark to observe these remarkable creatures up close. During your patrols, you will identify individual turtles, record essential measurements, and monitor their health. You may also collect skin samples for genetic research, attach satellite transmitters to track their movements or assist in relocating eggs from nests at risk of being washed away. With sea turtle populations declining, every piece of data-and every turtle-plays a crucial role in their conservation.
