What then are the advantages of airborne geophysical surveys over ground methods?

Edited by Admin
The advantages of airborne surveys include low data acquisition costs; widespread coverage; detailed coverage as required; high resolution; and in some cases, the ability to drill directly from the survey results.
On the other hand, ground geophysics supports additional methods not possible in the air, including:
  • Seismic tomography.
  • Induced polarization.
  • Ground penetrating radar.
  • Magnetotellurics methods. 
And so, in reaching a brief conclusion, it can be said that airborne geophysical surveys in general fit the role of a first pass and sometimes, complete method whereas ground geophysics provides additional detail over ground that can readily be accessed on foot or by helicopter.

Specialists in Airborne Geophysical Surveys

Terraquest was established in 1984 and since then, our dedicated team has flown over 1,500 airborne geophysical surveys using both fixed wing and helicopter platforms.  Our professional crews provide significant experience having carried out airborne magnetic surveys, airborne gravity surveys, airborne radiometric surveys, and airborne electromagnetic surveys on five continents. 

Our quality data sets have been utilized in the exploration for base and precious metals, kimberlite, hydrocarbons, uranium, rare earth minerals and water.  The company has performed exemplary surveys for both small and large exploration groups as well as many government agencies.  References can be provided upon request.
