Abstract : Examining INTIMATE'96 field data we see clearly the effects of tidal changes, i.e., of changing water depths for a bottom-tethered vertical array at mid-frequencies (300 - 800 Hz). This work will examine the sensitivity of such data via Matched-Field Processing (MFP) to tidal changes where the depth varies of +-1.0 m from the nominal 135 m. Is it possible to invert such data to estimate water depth as a function of time (tide) ? Are the data dominated by source range estimates where water depths are known to shift in a predictable fashion as a function of source range errors ? Results reported here will be for simulated data.
