The Icelandic Diving Service provides a service in seismic profiling. This is in essence comparable to echo sounding in depth measurements, but also uses sound reflection to measure the thickness of bottom sediments and depth to bedrock.
Seismic reflection has been used in Iceland for many purposes in recent decades. For example, it has been used to map thicknesses of maërl deposits in northwestern Iceland and calculate their volumes. Sand and gravel deposits in various parts of the country, especially in SW-Iceland, have also been mapped with this technique. Seismic reflection has proved to be an important precursor to construction in the marine environment, such as harbour installations and pipelaying projects.
