LISST-STX Door Open and Close - Full View - Video
This brief video demonstrate the open, flush, and close cycle of Sequoia Scientific, Inc.'s LISST-STX instrument for measuring the size and settling velocity of suspended sediment in situ. At first the doors are closed, and the propeller spins up to stir up the sediment that settled out in the previous settling experiment. The the propeller stops, the doors slide open, and the propeller spins up again to blast out the recently resuspended sediment while at the same time drawing in a new sample from the top. Then the propeller stops, the doors slide shut and the settling experiment begins.
