A sandbar divides the Chukchi Sea, at left, from the Kasegaluk Lagoon, right, near North Slope, Alaska. Sandbars are semi-exposed ridges of sand that waves deposit offshore from a beach. Generally, a stormy season's strong surf builds higher, wider sandbars, whereas gentle seas sculpt smaller sandbars closer to shore.
