Remote Sensing Surveys

Marine surveys require sophisticated instrumentation and experienced operators to be successful. Coastal Marine Salvage employs the latest in underwater search technology, and our staff has decades of combined experience to add to your project. We have located and confirmed targets from centuries old shipwrecks, to modern vessels, air & space craft, and more.

Magnetometer Surveys
A Magnetometer is used to detect the presence or absence primarily of ferrous metals (Iron & steel). We use the latest technology Cesium vapor magnetometers coupled with highly accurate positioning systems to accurately map anomalies found. Magnetometer technology is a principle tool use to locate anchors, weaponry, ships fittings, hardware, cables, and many other items.

A magnetometer is also extremely useful for locating objects that are covered with sediment. The instrument is utilized by pulling a towfish behind a vessel over a predetermined search grid. The data is stored digitally using onboard computers and is processed with complex software employed to further identify any magnetic anomalies. Coastal Marine Salvage has employed this equipment in a multitude of environments with excellent results.

Side Scan Sonar Surveys
Sidescan sonar is a technology that is used to "see" acoustically underwater. The technology is based on emitting sound pulses of energy laterally underwater and electronically listening to the sound waves that are reflected back by objects and the seafloor. The end result is a near video quality acoustic image of the target area. We have deployed our equipment in a multitude of conditions with positive results. Our resume includes locating submerged vessels, space craft, aircraft, obstructions, pipelines, cable route surveys, victims, weapons, anchors, and a myriad of other targets. We are equipped and have experience in both shallow and deep water environments contact us to inquire how we can help.
