Figure 26. The Leger dredge sounder in the descending position. This sampling device was designed to retain a portion of the captured sample even if a rock held the jaws open after being activated to snap shut. This sounder was tested twenty-two times in 1903 on the PRINCESS ALICE II between depths of 18 and 4560 meters.
