Ocean Tomography

Acoustic paths Perth to Bermuda Brian Dushaw has been looking at the MITgcm ECCO2 state-estimates with help from Dimitris Menemenlis. Brian finds that by using the hydrography from the state-estimate, together with some enhanced resolution bathymetric data in key regions, he can reconstruct acoustic paths between Perth and Bermuda that were first measured in the 1960s. Previous ray-tracing efforts to reproduce this observed pathway computationally have not succeeded ….
