First wide-angle view of channelized turbidity currents links migrating cyclic steps to flow characteristics

  title={First wide-angle view of channelized turbidity currents links migrating cyclic steps to flow characteristics},

Field observations of turbidity currents remain scarce, and thus there is continued debate about their internal structure and how they modify underlying bedforms. Here, I present the results of a new imaging method that examines multiple surge-like turbidity currents within a delta front channel, as they pass over crescent-shaped bedforms. Seven discrete flows over a 2-h period vary in speed from 0.5 to 3.0 ms(-1). Only flows that exhibit a distinct acoustically attenuating layer at the base… CONTINUE READING
