Automatic Identification of Internal Wave Characteristics Affecting Bathymetric Measurement Based on Multibeam Echosounder Water Column Data Analysis

Automatic Statistical Processing of Multibeam Echosounder Data

This paper presents the CUBE (Combined Uncertainty and Bathymetry Estimator) algorithm. Our aim is to take advantage of statistical redundancy in dense Multibeam Echosounder data to identify outliers while tracking the uncertainty associated with the estimates that we make of the true depth in the survey area. We recognize that a completely automatic system is improbable, but propose that signi...

Development of a Method for the Estimation of Multibeam Echosounder Measurement Accuracy

This article presents a method developed for the estimation of measurement error values (and their distribution) that occur in the process of marine sounding by a multibeam echosounder. The method, based on real data obtained in a specific marine environment, yields much more precise information on measuring instrument accuracy. The author also describes research done on a test set of more than...

The Development of the Multibeam Echosounder: A Historical Account

me first paper on narrow-beam echosounding was published in 1960. Since then, the advantages of the principle of multibeam swath bathymetry for seabed mapping have been recognized by many institutions working in the field of underwater area mapping. We intend to review some of the developments the multibcam cchosoundcr has undergone in order to better understand the challenges facing the field ...

Column: Factors Affecting Data Decay

Preliminary Test of Tide-independent Bathymetric Measurement Based on Gps

A GPS system was designed to carry out so-called ‘tide-independent’ bathymetric measurement, in order to compare with the conventional technique in which the tidal observations are made at tide gauges along the coast. Through the estimation and introduction of attitude parameters and height corrections, both based on the GPS solutions, the tide-independent bathymetric measurement can be impleme...
