Figure 2. A locator map of the study region in the Mid-Atlantic Ocean with white contours showing the 50m and 200 m isobaths, and color background with black contours showing the 16-year mean sea surface height calculated from the experiment with data assimilation (EX.DA). Shown here is a sub-domain of the northwestern Atlantic Ocean model (NWAOM) which otherwise covers a larger region 98W-55W and 6N-50N (see text).
