This dataset presents along-tank flow velocity and video observations, in MPEG-4 (.mp4) format, of aSOA particle motion captured with four cameras in November 2016. Along-tank flow velocities were collected by a single Vectrino acoustic Doppler profiler located centrally in the small-oscillatory flow tunnel housed at the NRL, Stennis Space Center, Mississippi. The videos provide information about the flow conditions present during various phases of particle mobility (incipient, rocking, and rolling/overturning). Each video file contains a unique name consisting of the experiment run number and trial, which is related to the corresponding video. Video containing the same particles on the same day are archived together in a zip file. Additional experimental settings are located in 2016-364-DD_Data_Table.csv and Data_Dictionary.csv.
