To understand the acoustic and physical properties of piston core samples collected from the Sunda continental shelf and analyze their distribution patterns
the samples were analyzed in laboratory
from which three provinces were divided in sound speed
sound speed ratio
porosity
wet bulk density
and maximum shear strength. Province Ⅰ had lower sound speed and sound speed ratio (
<
1.04)
high porosity
and low wet bulk density. Province Ⅱ had higher sound speed and sound speed ratio (
>
1.04)
low porosity
and high wet bulk density. Province Ⅲ had the lowest sound speed and sound speed ratio (0.99)
highest porosity (81%)
and lowest wet bulk density (1.34 g/cm
3
). The distribution pattern indicates that sediment movement
sediment source
topography
and hydrodynamic conditions influenced the distribution of acoustic and physical properties. Furthermore
we investigated the relationship of the maximum shear strength to the porosity and wet bulk density
and found that the maximum shear strength was proportional to both the porosity and wet bulk density. This finding has significant implications for ocean engineering applications.
