Description 106-108
Measurements of acoustic velocity and density on polymetallic nodules
(diameters in range 1.7-5.1 cm) have been taken using through transmission
pulse technique at low frequencies in the vicinity of 80 kHz, using low frequency
probes based on sandwich construction. The measured results show a significant
statistical variation in the values of acoustic velocity and density indicating
a large variability in the composition and structure of the nodules. The
average acoustic velocity, density and computed acoustic impedance and
reflection coefficient show higher values as compared to those of deep sea
sediments. The reported data is expected to be of use to scientists engaged in
acoustical survey of sea bed near mine sites of polymetallic nodules.
