Duck, N.C.—
For three days in September, they dug holes in the beach, but not for sand castles. WHOI scientists Steve Elgar, Britt Raubenheimer, and a team of graduate, undergraduate, and high school students excavated a hole 1.8 meters (5.9 feet) deep and 10 meters (33 feet) wide at the U.S. Army Corps of Engineers Field Research Facility. Using current meters, surveying equipment, and dyes, they measured the flow of sand and water as the hole was covered and uncovered by tides. The goal was to learn how long a crater would last in the swash zone, and whether it would create rip currents or other flows of water that could impede amphibious landing craft.
