The study found that adult leatherback turtles foraging in the northeastern Gulf of Mexico mainly feed along the west Florida continental shelf, with some females traveling to nesting beaches in the Caribbean, while a few individuals forage in waters of the central Gulf of Mexico.Migration of adult females through the Yucatan Channel indicates its seasonal importance for Caribbean nesting assemblages.
We deployed 19 satellite tags on foraging adult leatherback turtles, including 17 females and 2 males, captured in the northeastern Gulf of Mexico in 2015, 2018, and 2019 in order to study regional distribution and movements. Prior to our study, limited data were available from leatherbacks foraging in the Gulf of Mexico. Tag deployment durations ranged from 63 to 247 days and turtles exhibited three distinct behavior types: foraging, transiting, or rapidly switching between foraging and transiting. Some females were tracked to nesting beaches in the Caribbean. Most of the leatherbacks remained on and foraged along the west Florida continental shelf whereas a few individuals foraged in waters of the central Gulf of Mexico during the autumn and winter. In addition, migration of adult females through the Yucatan Channel indicate that this is a seasonally important area for Caribbean nesting assemblages.
