Determination of nautical depth by density measurement and by acoustic sounding

Gajewski L., Morgas W., Rudowski S.

Biuletyn Instytutu Morskiego w Gdańsku

1999

Vol. 26, No. 2

57--65

Pilot investigations were carried out with the objective of testing the usefulness of measuring the density of the mud/water medium to determine nautical depths in the Port of Gdansk. Results show significallt differences between the nautical depth and the depth detennined by acoustic methods at loose bulk cargo terminals. It was also found that too large depth values were obtained when 33 kHz transducers were used. Applicability of acoustic profiling for distinguishing structure of deposits which must be dredged was tested.
