Spatial and Temporal Variability of Cross-Basin Acoustic Ray Paths

摘要

It was suggested by Munk and Forbes (1989) that climate induced changes in oceantemperature may be monitored by measurements of cross-basin acoustic travel time variability. The feasibility of such a monitoring system depends on the spatial and temporal variability of the cross-basin acoustic paths in the presence of ocean variability of many different scales. For this thesis the variations in arrival position, azimuthal arrival angle, ray trajectory and the corresponding
