Answer: determining the structure of sediments and basement rock
Seismic profiling is the process of analyses of surface and subsurface characteristics of earth with respect to the seismic activities like volcanic eruption, earthquakes. These seismic activities can be measurement depending upon the type of sediments and rocks deposits at the base of the earth. It can also include striagraphy which gives idea about different layers of rocks deposition with seismic activity.

Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
