Particle paths in the surf zone in Sylt

Buoyant particle paths measured in the surf zone in Sylt, obtained from a long-range stereo imaging system. A pair of 5MP digital cameras (Victorem 51B163-CX, IO Industries) were fitted with 200mm Canon EF 200 mm f/2.8L lenses, and captured the paths of oranges in the surf zone in Sylt, an island off the German North Sea Coast. The cameras were positioned on the dune overlooking the sea, at a distance of approximately 35 m from one another, and captured a portion of the wavy water surface located about 150 m away from the cameras. The cameras were triggered simultaneously using a PCIe6612 counter/timer combined with a SCB-68A terminal block (National Instruments). A total of 14 lagrangian particle paths are provided, acquired between 17:00 and 17:30 UTC on September 7th, 2019.
