Résumé

Results obtained by using directional sounding equipment are presented together with a discussion and illustrations. It is shown that directional traces can be considered slope-corrected and that they exhibit other characteristics which can be utilized to advantage on hydrographic surveys in deep ocean areas.

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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