In order to full use of the navigational area in Tianjin Port and the depth above mud layer,we have swept the area both with 4-beam bi-spectral sounder and sweeping instrument.The result of the test shows it is possible to make an effective overall survey for the navigational depth above mud.This paper introduces especially the constitution and operating method of the axle-towed mud-layer sweeping instrument.
