Only water depths between about 2 and 6 m below mean sea level are shown to increase the vertical resolution of the color scale.
Dark blue is deeper water, light blue is shallower water.
The features are described in the next figure. Annotated version of the survey near Truro. To the south are bifurcating bars, and a really wild set of cross-hatched bars. Farther south, just north of the Pamet Harbor entrance, the shallow nearshore area extends farther offshore, and there are fewer or more subtle bars. Depth versus along-track distance.
