英文摘要	Geo-acoustic properties such as P-wave velocity, wet density, and fractional porosity can be continuously measured using multi-sensor core logger(MSCL), which has widespread use globally. Six gravity cores from the Southern Beibu Gulf, the South China Sea were measured in the laboratory using MSCL for P-wave speed, wet density, and porosity parameters. Both the wet density and porosity of one core were also measured after sub-sampling. Results of the comparison of the two data sets show a reasonable match, and the depth of the sample has little effect on the change in sound velocity. Polynomial, Spline interpolation, and GAM model regression can obtain a higher R2. GAM model can provide a sound velocity prediction method that is close to the measured value. The advantage and disadvantage of using MSCL as a tool for geo-acoustic measurement is that it can obtain a large number of high-density and high-precision data for sediment acoustics and other parameters. However, if air is mixed with sediment samples, it will distort the results of MSCL. This work can offer a sound background for regional ocean sediment development, regional environmental comparisons, and bottom geo-acoustic models, and for the future effective use of MSCL.
