Abstract

Project swathmap (one of four deep-water, long-range sidescan sonars in operation today) is the low-cost peacetime application of a U.S. Navy antisubmarine warfare system utilized on routine ocean-wide combat vessel transists. While resolution is not sufficient to observe bathymetric structures in detail, the system is particularly adept at locating them and determining continuity. Routine observations include terraces, trench-crossings, fracture zones, abyssal hills, craters, seamounts (many of them new) often topped by craters, and abyssal hills (superb clues to plate tectonic motion).

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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