Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. Geophysicists, who usually study geophysics, physics, or one of the earth sciences at the graduate level, complete investigations across a wide range of scientific disciplines. The term geophysics classically refers to solid earth applications: Earth's shape; its g… WebGeophysical data attributes describe information for offshore geophysical activities. The shot point layer contains only location information and metadata, whereas the survey line (seismic reflection and sonar) layers include information about the equipment types used on the line and links to scanned images of the geophysical records where the ...
