This figure shows seasonal and storm-induced changes in shoreline position averaged over the Cape Cod bluff-backed coast (from 17.5 to 45 km on the along-coast reference scale shown on the Cape Cod study area map). The horizontal scale is time labeled in month/year since April 1988, and the vertical scale is the shoreline position relative to the first survey. Each point on the figure represents a shoreline survey from a biweekly sampling program initiated in April 1988. A decrease in shoreline position indicates a landward shift in the position of the mean high water contour, which is inferred to be associated with beach erosion.
