Hydrographic Survey

Hydrographic surveys use sonar to collect highly accurate water depth and bottom contour information. These echo sounding systems are based on the principle that when a sound signal is sent into the water it will be reflected back when it strike an object. Read more


Sub Bottom Profiling Survey

Sub bottom profiling systems identify and measure various marine sediment layers that exist below the sediment/ water interface. These acoustic systems use a technique that is similar to single beam echo sounders. Read more



Side Scan Imaging Survey

Side-scan imaging surveys use sonar to efficiently create a precise acoustic image of large areas of the sea floor. Side scan sonar uses transducers that emit fan-shaped acoustic pulses down toward the seafloor across a wide angle perpendicular to the path of the sensor through the water. Read more
