Abstract
This report describes a review of current literature on the interaction of underwater sound with the sea surface. The document discusses current areas of scientific research on this topic, as well as the current capabilities of a few popular acoustic models. Recent scientific research shows that the creation of bubbles by wind-driven waves can have an important influence on transmission loss and reverberation. Under certain circumstances this is even true at moderate (low-kilohertz) frequencies. Most of the acoustic models currently in use for sonar performance prediction may not take all of the important interactions with the sea surface into account.
