Figure 1: Stretching filaments (colors) and positions of loggerhead turtles (black dots) during the year 2004. The stretching filaments correspond to the unstable manifolds of the surface geostrophic flow obtained by calculating the finite-size Lyapunov exponent (FSLE) from satellite-derived sea surface height (SSH).
