El viaje de las tortugas en peligro por las corrientes oceánicas revelado por el satélite   A leatherback turtle leaving the beach of Awala-Yalimapo in French Guiana. Atlantic beaches around this area are considered to be the last major nesting sites for the species.   Leatherback turtle path overlaid on absolute dynamic topography maps (MADT) gathered from space-borne radar altimeters. This turtle went due north after leaving its nesting site in French Guiana, and then slowed down in the nutrient-rich front area between Gulf Stream and Labrador Current. On September 13, 2000, this turtle is swimming at the eddies' border. The radar altimeter data used here comes from ERS-2 and TOPEX-Poseidon; currently Envisat, Jason and GFO are being utilised in the same way.
