This article discuses a recent turbidity current that scientists were able to record. The scientists used boulder shaped sensors to monitor the turbidity current by rolling with the flow. The smart sensors clocked the flow at 18 miles per hour. The article also talks about a previous turbidity current in 1929 that traveled at about 60 miles per hour. They were able to calculate the speed of the 1929 flow by observing when certain points along a transatlantic telephone cable began to break. Perhaps these new sensors can lead to a better understanding of turbidity currents.
