Descrição: Our long-term goal is to study the sensitivity behavior of acoustic phase arrival times, as an alternative observable offering increased resolution (compared to peak arrivals), for the recovery of sound-speed perturbations in the ocean. The objective of this work is to study the behavior and sensitivity of ocean acoustic phase arrival times due to sound-speed changes, in comparison to those of peak arrival times. The aim is to derive perturbation relations and sensitivity kernels connecting sound-speed and travel-time perturbations, and, further, to study the behavior of phase arrival times and its predictability, depending on propagation and signal characteristics.
