Abstract:

The purpose of the bottom interaction experiment is to examine the influence of the ocean bottom on low frequency acoustic propagation. This document describes the goals of the experiment, the design of the experiment, including site selection, and details of conducting the experiment, and includes the data analysis plan. The bottom interaction experiment will use ACODAC recording systems to obtain a record of SUS signals in a bottom limited region. The geometry will be selected so that the number of bottom interactions and the bottom interaction angles will be known. Data will be collected at short ranges with a small number of bottom interactions to duplicate previous measurements. Data will also be collected out to maximum range permitted by SUS source level to ensure the maximum number of bottom interactions and small grazing angles.
