A Review of Ocean Acoustic Tomography: 1987–1990

The techniques and instruments used in acoustic tomography of the oceans are surveyed, and results are summarized. Sections are devoted to theoretical studies and numerical simulations (mesoscale mapping, vertical-slice tomography, flow imaging, and nonlinear bias), series of tomographic experiments, analyses to identify global changes, and outstanding problems (the forward and inverse problems and ocean physics). Typical data are presented in tables and graphs, and a comprehensive bibliography is provided. 72 refs.
