Supplemental Animation from Blue whales increase feeding rates at fine-scale ocean features

Animation showing the hourly movements over several days of a blue whale that was tagged off the coast of Southern California in 2017. Feeding behavior (green and blue markers) was determined from the stereotypical kinematic signature of blue whale lunge feeding derived from the tag's high-resolution sensors (e.g. pressure, accelerometer). Whale foraging locations are overlaid with Lagrangian features (i.e. Finite-Time Lyapunov Exponents, FTLE) at hourly increments using data from coastal High-Frequency Radar stations (Black and white diamond markers). FTLE was calculated by integrating a grid of evenly-spaced tracers backward in time over a 48-hour period for each time-step.
