Figure 9. Willard Beach, South Portland. (a) Standard deviation data at WI3 (top, a) indicate marked variability at the 55 m mark in both summer (red) and winter (blue) profiles, but notably summer (variations up to 35 cm). Offshore sand storage during winter (at 110 m) varies to about 35 cm vertically as well, indicating that the sediment that is lost from the beach berm area in the summer is stored offshore in the winter each season. (b) At WI4 variability is small along the entire profile.
