Haro Strait topography (water depths)

Results have previously shown (most recently at the Honolulu meeting of the ASA, 12/06) that determining important geometric parameters for a single SR path of the Haro Strait test is problematic. In particular, many combinations of parameters will reproduce (via the Collins RAMPE) the observed time-domain arrivals seen in the data. These geometric parameters include water depths at the source and array phones. More recently multiple sources to a single array have still not produced a unique ‘‘solution’’ per SR path. This paper will select depths from the reduced yet allowable set of values and attempt to estimate a more global topography for the region via a tomographic method developed earlier.
