Gabon Olive Ridley Project

Data provider
Gabon Olive Ridley Program
Originating data center
Satellite Tracking and Analysis Tool (STAT)
Project partner
In conjunction with Parc National de Mayumba, the Wildlife Conservation Society, Aventures Sans Frontieres, researchers from seaturtle.org, the University of California - Santa Cruz and the University of Exeter have attached satellite transmitters to female olive ridley turtles nesting at Mayumba National Park, Gabon.

Advances in tracking technology have created a global understanding of sea turtle at-sea movement and behavior. This combined with efforts to understand the global distribution of human interactions with sea turtles gives the ability to enact global sea turtle conservation. Strikingly missing from this suite of understanding is the olive ridley sea turtle (Lepidochelys olivacea), particularly Eastern Atlantic populations. Using satellite tags deployed from Gabon, Africa, we aim to determine olive ridley foraging strategies and oceanographic habitat, determine multi-species turtle hotspots, and their interactions with fisheries. This will result in a greater understanding of one of the least-studied species of sea turtle, where this species overlaps with other sea turtle species, and the ability to create effective fishery mitigation leading to comprehensive sea turtle conservation.
