Abstract

In 2008, students of the University of Southern Mississippi surveyed a portion of the Pearl River. Due to the ultra-shallow nature of the survey area, a multibeam mount was constructed that tilted the transducer 35o to the side with respect to nadir. Such an orientation had predicted gains of 60% in the center of the channel and facilitated the collection of data further inshore than otherwise possible. To compensate for excessive outer beam noise, a CUBE surface filtering regime was adopted. Crosscheck analysis showed the acquired data easily met IHO S-44 1a standards. This paper details the evaluation and results of such a non-traditional mount.

  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:

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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).
