Traykovski also deployed underwater devices he called “quadpods” in the inlet. These 7-foot-tall, four-footed frames were equipped with current meters to measure water flow and turbulence and downward-aimed sonars trained on 108 square feet of sand. The sonar images, taken every 30 minutes, showed details of how and why sand moves back and forth as tides and currents move over it. (Peter Traykovski, Woods Hole Oceanographic Institution)
