Here the user specified destination 4.61 km from the site. The new red line from the site to destination is the vertical vs range cross section of the ocean the program will acoustically model. The red circle will be the maximum limit for the horizontal, constant depth prediction. Overlaid in blue is the cross sectional area that is to be acoustically investigated. This web page can simulate the rotation with AVI movie by double clicking on the image above.
RAM takes into account varying speeds of sound for different depths.
After the bathymetry is rotated it is displayed to the lower right hand corner, and the majority of the figure is replaced with the Range vs Depth TL prediction. Note the program will not attempt to predict the full area of the circular range where the land is present. The figure now asks the user to click the mouse over a any desired path. When the path is completed the user presses the return key. The path is plotted over the map with a black dashed line.
