Automatic Processing of High-Rate, High-Density Multibeam Echosounder Data [PDF]
, 2003 Multibeam echosounders (MBES) are currently the best way to determine the bathymetry of large regions of the seabed with high accuracy. They are becoming the standard instrument for hydrographic surveying and are also used in geological studies, mineral ...

Multibeam Echosounder With Orthogonal Waveforms: Feasibility and Potential Benefits [PDF]
IEEE Journal of Oceanic Engineering, 2021 Modern multibeam echosounders (MBE) employ frequency-division techniques (FDT) to ensonify multiple sectors within the same ping cycle. This leads to improved performance in coverage rate, and yaw and pitch stabilization. However, it introduces a bias among sectors because MBES systems are frequency dependent.

A comparison of supervised classification methods for the prediction of substrate type using multibeam acoustic and legacy grain-size data. [PDF]
PLoS ONE, 2014 Detailed seabed substrate maps are increasingly in demand for effective planning and management of marine ecosystems and resources. It has become common to use remotely sensed multibeam echosounder data in the form of bathymetry and acoustic backscatter ...

Observed correlations between the sediment grain size and the high-frequency backscattering strength [PDF]
JASA Express Letters, 2023 In March 2019, Teledyne RESON and the Applied Physics Laboratory at the University of Washington conducted surveys with a calibrated multibeam echosounder at ten sites in Sequim Bay, a shallow sheltered bay in Washington State, USA.

A fisheries acoustic multi-frequency indicator to inform on large scale spatial patterns of aquatic pelagic ecosystems [PDF]
, 2013 Fisheries acoustic instruments provide information on four major groups in aquatic ecosystems: fish with and without swim bladder (tertiary and quaternary consumers), fluidlike zooplankton (secondary consumers) and small gas bearing organisms such as ...

The Invention and Developing of Multibeam Echosounder Technology [PDF]
Polish Hyperbaric Research, 2018 Abstract When a man has mastered the ability to travel by sea, he began to wonder what is the depth clearance under the keel and how to measure the depth. Initially, only coastal shipping was practiced. Cargo ship sailing, fishery, underwater scientific research, recreational diving as well as resource exploration and operation of ...
