FIG. 1.

A cross section of a cylindrically symmetric seamount is shown with a representative sound speed profile and the ring source location.

FIG. 2.

The range discretization for the stepwise coupled mode solution is shown with the modal coefficients of the outgoing (a’s) and ingoing (b’s) waves in two adjoining regions.

Image of FIG. 3.
FIG. 3.

The sound speed and bottom profile used for the area surrounding the Dickins seamount is plotted versus depth. The water depth is . The refracting sediment is thick. The acoustic basement has a sound speed of .

Image of FIG. 4.
FIG. 4.

The beam response of the incident noise field and total (incident plus scattered) fields is shown versus elevation angle. The solid curve is the incident noise field, without the seamount, and the dashed curve is the total field, with the seamount present. The vertical directivity of both fields is similar except in regard to level: the total field intensity is reduced by interaction with the seamount.

Image of FIG. 5.
FIG. 5.

The beam response of the ingoing and outgoing incident noise fields, without the seamount, is plotted versus elevation angle. The solid curve is the ingoing noise field and the dashed curve is the outgoing noise field.

Image of FIG. 6.
FIG. 6.

The beam response of the ingoing and outgoing components of the total field, with the seamount present, is plotted versus elevation angle. The solid curve is the ingoing field and the dashed curve is the outgoing field. The ingoing component of the total field is the same as the ingoing component of the incident noise field in Fig. 5 . The outgoing component is reduced in level by interaction with the seamount.

Image of FIG. 7.
FIG. 7.

The beam response of the incident noise field and the scattered field is shown versus elevation angle. The solid curve is the incident noise field, without the seamount, and is the same as the solid curve plotted in Fig. 4 . The dashed curve is the scattered field and appears similar to the outgoing component of the incident noise field plotted in Fig. 5 .
