Multibeam Crosscheck Analysis A Case Study

Authors

  • Jørgen Eeg Danish Maritime Safety Administration

Abstract

A new method for analyzing overlapping areas in multibeam surveys is introduced. The method requires that the velocity of sound in the water at the transducer is monitored during the survey. The method applies the principle of least squares to determine the vertical offset and the bias of the swaths caused by insufficient knowledge of the velocity of sound in the water column below the transducer. The precision and robustness of the method is demonstrated on a survey.

Authors should also bear the following points in mind:

  1. The title should be concise and reflect the subject matter
  2. Long passages of text should be avoided by the appropriate use of sub-titles
  3. References, which should include only publications cited, should be referenced in the text, thus (Smith, 1988), and be listed alphabetically in the Reference section conforming to the Harvard style. Some typical examples follow:

(i) References from Journals:

Please note that articles will be returned to Authors who do not conform to the IHR referencing policy.

Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form. In such cases referred material can be cited using numbered superscripts in the text and the list of references thus replaced by a section headed 'Notes' in which explanation of the superscripts is given. Material which has been consulted but not specifically referred to in the text can be included in a separate 'Bibliography'.

Please note that references will not be checked by the Editor and the responsibility for the accuracy rests solely with the author(s).
