Contract Hydrographic Surveys

Authors

Abstract

National hydrographers — with responsibility for surveying to the accuracy needed for navigational safety — have been under pressure to keep pace with the rapidly increased draught of tankers, operating along new routes to new ports and offshore terminals, and accepting reduced underkeel clearances, at a time when offshore hydrocarbon and other new marine resource activities have called for extensive data collection, interpretation and presentation of quite different sets of parameters. The paper describes how contract surveys have been used to increase the surveying carried out for the safety of navigation in British waters.

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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