Abstract

Abstract

Based on the sound speeds of seafloor sediments measured in-situ in the middle area of the southern Huanghai Sea, the correlations between the in-situ sound speeds and the physical parameters of seafloor sediments such as density, moisture content, porosity ratio and percent porosity are analyzed.The predicting equations of the in-situ sound speeds are established by means of a regression analysis.The result shows that there are good correlations between the in-situ sound speeds and the physical parameters with the coefficients r>0.95.The comparison between the predicting equations of the in situ sound speeds and those established based on the sound speeds measured in laboratory on board indicates that their average deviation is 22.6 m/s with a minimum of 15.8 m/s and a maximum of 31.3 m/s.The comparison between the predicting equations of the in-situ sound speeds and those developed by other authors demonstrates a distinct difference among the different predicting equations of sound speeds, and the reasons are discussed
- sound speed of seafloor sediment,
- in situ measurements,
- physical properties,
- predicting equations of sound speed,
- the southern Huanghai Sea
