This project seeks to develop a more detailed understanding of the relative density of at-sea habitat use for the olive ridley (Lepidochelys olivacea) turtle to allow for more effective marine spatial planning efforts in support of marine protected area design, fisheries management and petrochemical exploration activities. The project is funded by Tullow Oil, the Darwin Initiative and Busch Gardens Sea World Conservation Fund.
