Geolocation Journeys supports marine conservation and scientific discovery by providing tracking devices (called geolocators) to projects that investigate the journeys of marine top predators. This year a collaboration between Prof. Mary-Anne Lea from the University of Tasmania and Prof. Nico de Bruyn from the University of Pretoria were supported with 25 new geolocators to follow the migrations of Antarctic Fur Seals on subantarctic Marion Island. This unique long-term study

Geolocators have helped reveal the foraging strategies of fur seals during the Antarctic winter. Our new paper published this week used a combination of geolocators and time-depth recorders to track the movements and dives of female seals from sub-Antarctic Marion Island in the Southern Indian Ocean. During their 8 month winter foraging trips these relatively small animals (females weigh 30-40 kg) face a choice: stay close to the island but expend more energy diving deeper an
