2. Seismic Reflection Data

   Linked via "seismograms"

   Seismic reflection data is a geophysical imaging technique used primarily in the exploration of subsurface structures, most notably in petroleum geology, engineering seismology, and crustal studies. The method involves generating controlled acoustic energy sources—seismic waves—at or near the Earth's surface and recording the subsequent reflections of these waves off subsurface boundaries (horizons). These boundaries typically represent contrasts in the acoustic impedance (AI)/) of adjacent geological formations, where $\text{AI}…
