First iteration

I applied the fitting goals () and obtained a $\bf \Delta s$ (Figure 11). The most dramatic feature of Figure 11 is the change in salt position, forcing an increase (black) in the velocity. In addition, note the increase in velocity in the right basin, and a decrease in velocity further to the right. The left portion of the model shows a relatively localized increase in the velocity at approximately 2500 m in depth and 3200 m in the inline.
