SUB-BOTTOM PROFILING

Acoustic Sub-Bottom Profiling (SBP) systems are used to determine the physical properties of the seafloor and to image and characterise geological information several tens of meters below the seafloor.

Sub-bottom profile data is used for a range of purposes including:

• Geological surveys

• Sediment classification

• Inspection of the buried depth of pipeline & cable

• Archeological surveys

• Mining/dredging surveys

We use a variety of SBP systems to meet the strict requirements of customers such as:

• Edgetech 3200-XS

• Applied Acoustic Boomer and Sparker.

 

MARINE MAGNETIC SURVEY

A marine magnetic survey is the measurement of Earth's magnetic field intensity or its components along with a series of profiles over an area of interest with the objective of measuring the magnetism of the ocean floor. Magnetic surveys are also used to locate a magnetic material in the search for buried objects.

At VHS, The magnetometer in use are:

• Marine magnetic Sea Spy

• SeaQuest 3-Axis Gradiometer
