Sound Velocity for Multi-Beam Systems

Multibeam systems are the primary technology for mapping the sea floor.  However, multi-beam systems require instrumentation for sound velocity measurement and correction at the sea-surface and throughout the water column.  Without such measurements, multi-beam accuracy is jeopardized.  Most multi-beam systems include both a sound velocity profiler, such as Minos•X, and a sea-surface sound velocity instrument, such as a Micro•X with  SV•Xchange installed.

  What is a Multi-beam System?
Multi-beam echo sounders are now the standard technology used to survey the ocean bottom.  Click here to get an overview of how such systems function.
  Why is Accurate Sound Velocity Critical?
Sound velocity plays a critical role in ensuring multi-beam accuracy.  As multi-beam accuracies advance, the dependency on sound velocity - both at the sea surface and in the vertical profile - increases dramatically.  Click here to learn more.
  Who Manufactures Multibeam Systems?

There are a number of manufacturers of multibeam systems, including R2Sonic, Kongsberg, Reson, Atlas, and L-3 Elac.  Click here for a description of the sound velocity packages that AML offers for each manufacturer's system.
  Why Choose an AML Sound Velocimeter?

Measured sound velocity is more accurate than sound velocity calculated from a CTD by a factor of 10.  AML Oceanographic pioneered the measurement of sound velocity in the late 1990s.  More recently, AML is the only provider of sound velocity instrumentation to offer field-swappable sensor-heads.  Learn more...
