Revealing migratory behaviour of South African leatherback turtles

Nathan J. Robinson, Cape Eleuthera Institute

The data were collected from nesting leatherback turtles (Dermochelys coriacea) that tracked via satellite transmitters from the iSimangaliso Wetland Park, South Africa.

N/A

All the individuals were adult female leatherback turtles that were tagged while on their nesting beaches.

As these data have already been processed in a State-Space Model there is only one location per day and time is not available.

The dataset has been updated over time as outlined below. Each entry includes the version number, release date, type of change, and a short description.

Overview
