Equipment


EchoSounders

We measure the time it takes for sound waves emitted from the echosounder to return from the seafloor - this is the basic principle of Hydrography

Side Scan Sonar

A Side Scan Sonar (SSS) transmits high frequency sound pulses either side of the unit.

Sub Bottom Profiler

The sub-bottom profiler emits acoustic pulses at low frequencies which penetrate the seafloor.

Magnetometer

A magnetometer detects changes in the Earths’ magnetic field.

Seismic Sparker

The Geo-Spark 200 is used for sub-seabed investigations where very deep sediment penetration is required.

Light Detection & ranging (LiDAR)

LiDAR technology emits two laser light beams from a sensor on-board an airplane.
