Elephant Seal Satellite Tracking

We're over half way done with our satellite deployments for this season! Our team has been working hard to put instruments that track both diving behavior and location on 20 adult female northern elephant seals during their post-breeding foraging migration. This year we are putting instruments on 10 animals that we have tracked during a previous post-breeding migration to look at the effect of El Niño on their foraging behavior.

The first few animals have taken off already, you can check out the live tracking data here:

About This Project

Studies on marine mammal personalities are scarce, despite research showing that personality can relate to foraging behavior and fitness. This study will adapt a method for evaluating personality type in grey seals for use on northern elephant seals. Relating personality types to satellite tracks and reproductive success will help us understand how these animals respond to changes in their environment, which is particularly important given rapidly changing climatic conditions.
