On-the-ground measurements are notoriously difficult in the harsh environment due to tsunami, but satellites could help close the gap in measuring water masses. There is no doubt that the tsunami performs a remarkable role to alternate the physical properties of the ocean through mixing turbulent approaches. In continuing with Chapter 9, the tsunami accelerated the water salinity in Aceh coastal waters to approach the maximum value of 38 ppt. Ocean salinity is a keystone of measuring water mass physical properties by compiling the temperature of a water body.
