Marine geophysicists are primarily concerned with the application of gravity, magnetics, heat flow, and seismic methods to study the structure of the earth beneath the oceans. ... Tectonic, volcanic, and hydrothermal activity at mid-ocean ridges, and the structure of the oceanic crust.

What is geophysicist do?

Geophysicists apply the principles and concepts of physics, mathematics, geology, and engineering to the study of the physical characteristics of the earth and other planets. As a geophysicist, you would measure gravity and magnetic fields, seismic waves, temperatures, and natural electric current.

What is marine geophysics?

Marine geophysics is a scientific discipline which uses the quantitative observation of physical properties to understand the seafloor and sub-seafloor geology. Both active and passive sensors are used to measure the shape and hardness of the seafloor as well as to define and map sub-seafloor structures.
