Grab Samplers are one of the most common methods of retrieving soil samples from the seabed surface. The information they provide, although coarse, can be applied in a number of applications such as Bulk sampling for seabed minerals, Marine aggregate prospecting, Environmental sampling, Pre-dredge investigations & Ground-truth for morphological mapping and geophysical survey.

Acoustic Sub-Bottom Profiling (SBP) systems are used to determine physical properties of the sea floor and to image and characterise geological information a few metres below the sea floor. Sub-bottom profilers are usually comprised of single channel source that sends sound pulses into the shallow sub-sea floor sediments. The sound pulses bounce off the sea floor and subsequent buried sediment layers according to differences in their acoustic impedance (hardness).
