23 Jun Sub-mesoscale Fronts Modify Elephant Seals Foraging Behavior

Wildlife Computers tags that include a temperature-depth recorder combined with an accelerometer allowing the detection of the rapid head movements that characterize prey capture attempts were used on 12 elephant seals over the course of three years. The study revealed that elephant seals attempt to catch more prey at shallower depths at submesoscale fronts compared to nonfrontal regions that include mesoscale eddies. It also found that they reduced their horizontal velocity likely to concentrate on their vertical diving activity.
