nexploded ordnance presents problems to workers and the general public as these explosive devices have been left behind from world wars and other conflicts. Over time these devices have been overlain by sediment at which point they have been buried to where they pose certain dangers to the public, and workers that are contracted for infrastructure projects. There is estimated to be around 15 million acres in unexploded ordnance in the U.S. alone. Geophysicists use Magnetics in order to locate the unexploded ordnance to prevent accidents and damage to infrastructure as these devices may still be active. This is done via a variety of ways and applications. By mainly using magnetic waves we are able to detect certain anomalies in data to a certain

Over the years technology has gotten better and different procedures and techniques have emerged. We now have the capability to look for UXO’s by using airborne magnetics which greatly improves the amount of ground we can cover, and allows for scans of about 400 acres per day (Billings, 2010). Airborne magnetics enable us to look for and find UXO’s in the terrestrial and shallow marine subsurface with ease by creating a string of data that can easily be interpreted over a large area.
These magnetometers (boom-mounted) are set on the aircraft directly or even on a tow cable. Over the years they have gotten significantly better and are now able to detect smaller UXO’s. In the early years of airborne magnetics they could only reliably detect the bigger UXO’s as they were more easily identifiable due to their size and their strong magnetic density contrast. The new boomer technology now allows us to be able to find, identify, and extract smaller ordnance reliably if conditions are ideal. Airborne magnetics significantly depends on the terrain that is being surveyed. If there is Basaltic rocks or other geology that is ferrous in nature it would mean problems for the extremely sensitive magnetometers aboard these aircrafts as many false positives would show up in the data (Doll,
