Data sets contain vertical profiles of current velocity measured by upward-looking Nortek AquaPro Acoustic Doppler Current Profilers (ADCP) deployed at two stations, an oyster bank (6.899° lng/ 53.546° lat, -32cm N.N) and a sand bank (6.898° lng/ 53.545° lat, -78cm N.N.), at Randzel 1 oyster reef in the Wadden Sea. Oyster bank station was located at the western edge of oyster reef, while sand bank station was positioned approximately 80 m to the southwest on a sandy seabed for comparison.
