Tracking leatherback turtles from the world's largest rookery: assessing threats across the South Atlantic
Despite extensive work carried out on leatherback turtles ( Dermochelys coriacea ) in the North Atlantic and Indo-Pacific, very little is known of the at-sea distribution of this species in the South Atlantic, where the world's largest population nests in Gabon (central Africa). This paucity of...

Despite extensive work carried out on leatherback turtles ( Dermochelys coriacea ) in the North Atlantic and Indo-Pacific, very little is known of the at-sea distribution of this species in the South Atlantic, where the world's largest population nests in Gabon (central Africa). This paucity of data is of marked concern given the pace of industrialization in fisheries with demonstrable marine turtle bycatch in African/Latin American waters. We tracked the movements of 25 adult female leatherback turtles obtaining a range of fundamental and applied insights, including indications for methodological advancement.
