Improvement of deep-sea dredging operations through the use of a depth meter

  • H. R. Kudrass


A battery-operated depth meter mounted inside the dredge is used to monitor the time-depth profile of a dredge haul. By comparing is profile with the water depth recorded by the ship's echosounder, the locations at which dredge samples were collected can be determined. The analysis of the time-depth profile can also be used to estimate the minimum length of the dredge wire, thus increasing the efficiency of dredging operations.
