Survey Technologies



We employ a wide range of state-of-the-art technologies including side scan sonars, sub-bottom profilers, magnetometers, and remote operated vehicles.

The magnetometer is a device that can locate ferrous metal objects above or below the sea bottom. It is useful in locating cables, pipelines, etc.

Side Scan Sonar:
Side scan sonar is a method of underwater imaging using narrow beams of acoustic energy (sound) transmitted out to the side of the towfish and across the bottom. Sound is reflected back from the bottom and from objects to the towfish. The data is then sent via a cable to a topside computer where it is processed and turned into a image. This system is useful in mapping the sea floor.

Sub-Bottom Profiler:
Sub-bottom profiling systems utilize the principle of seismic reflection.A sub-bottom profiler is a type of sonar that can image geology and man-made artifacts which lie beneath the sea bed.

Global Positioning System:
GPS is a worldwide radio-navigation system formed from a constellation of 25 satellites and their ground stations. GPS allows us to get an exact longitude and latitude anywhere on earth with a high degree of accuracy.
