    • The term "slope correction" is used in Refs. 16-18. We prefer the term "reverberation decay correction" because "slope correction" has also been used to describe corrections for the physical slope of the bottom (e.g., Ref. 28).

    • note
    • For these data, the significant reverberation decay corrections correspond to the change in physical mechanism at the critical angle. Reverberation decay corrections at angles below the critical angle are less than 2 dB. However, for longer pulse durations there would have been significant reverberation decay corrections over a wide range of grazing angles. For example, using a 50 ms signal instead of a 10 ms signal would increase the product of the slope and the pulse duration (the x-axis values in Fig. 7) by a factor of 5, leading to much larger reverberation decay corrections that would have been driven by the magnitude of the reverberation decay over the pulse interval.

    • note
    • Perturbation theory is perfectly adequate for many applications involving elastic bottoms [including limestone, when the frequency range is not too great (Ref. 8)]. For this case, we thought it prudent to use the more accurate small-slope theory because, though the theoretical advantage may be only marginal, the success or failure of an inversion algorithm can hinge on such minutiae.

    • note
    • We have been unable to explain this ripple. Its origins may lie in the deviation of the bottom characteristics from simple rough limestone. We do know that it occurs in grazing angle regimes that correspond to times before the arrivals of any multipaths, which excludes multipaths as the cause.

We do not emphasize this because (1) we have no data at such angles and (2) the theory that we are using has limited applicability at these grazing angles because it does not include shadowing.
