Direct Readout of Sediment Analyses by Settling Tube for Computer Processing

Sediment fall-velocities measured by the Woods Hole Rapid Sediment Analyzer can now be obtained directly on punched paper tape in a form suitable for processing by a computer. This technique saves much time because it eliminates manual card punching, a step in which an operator transfers values from sediment analyses to punch cards in order to make the data acceptable tocomputers.
