Abstract
Sophisticated acoustic models form the inner loop in most inversion schemes. Trust in these models has come from comparing their results to scale-model and at-sea experiments. The modeling is challenging, partly because ocean acoustic problems span a wide range of frequencies. At the high end we have sources squealing at megahertz frequencies, propagating sound just a few millimeters. This is the scenario for sing-around velocimeters used to measure the speed of sound in the ocean. At the low end sources rumble like the deepest organ notes at tens of Hertz making sound heard around the world. Such problems emerge for a new type of sing-around velocimeter proposed for monitoring global warming. Important decisions are made based on the models. Can they be trusted? We briefly review some of the efforts that have been made to answer this question.
