Temporal variation was assessed using Generalized Additive Models with individual identity as a random effect. Sequential organization was evaluated using run-length distributions and permutation tests (10,000 randomizations preserving each individual\u2019s dive-type totals). Spatial recurrence was examined qualitatively using locations from two GPS-instrumented females.
