Abstract: | Physical properties, sound velocity and density of 95 core samples from ten locations along a transect (parallel to 15°N latitude)
across the Bay of Bengal were measured. Results indicate that sound velocities range from 1,482 to 1,679 m/s (av: 1,583 m/s)
and densities from 1,338 to 1,757 kg/m3 (av: 1,527 kg/m3). It has been observed that dark colored clays and sandy clays show higher values of sound velocity and density than the
average values. A comparative study of the same with that of the sediment cores collected from the Norwegian basin, Mediterranean
Sea, and Hatteras, Nares Abyssal plains, western North Atlantic Ocean was done. |
