In 2001, researchers from the Loggerhead Marinelife Center and Duke University began surveying a stretch of beach in northern Palm Beach County to identify the number of individual leatherback sea turtles utilizing this very important beach. This small section of beach routinely hosts more than 55% of all leatherback nests laid in Palm Beach County. The highest nesting density (8 - 13 nests/km) in the continental United States is found here. Each year between March and June, we patrol a 12-mile stretch of each in search of nesting leatherbacks. Each individual that we encounter receives flipper tags and a microchip (PIT tag). These tags can be read if she is encountered when she returns to the beach to nest. In addition to tags, each turtle is measure and a small biopsy is taken for genetic analysis. We keep detailed records of every encounter to better understand the size and status of the leatherback population. The Loggerhead Marinelife Center is a 501(c)3 non-profit organization specializing in the education, research, and rehabilitation of sick and injured sea turtles. The leatherback research program is funded by private donors and grants. Please consider supporting this important research.
