Abstract

With advances in processing techniques, and the associated improvement in positioning accuracies, it is apparent that deriving estimates of water level from GPS height observations is becoming accepted as a viable alternative to traditional tidal solutions. This paper outlines GPS techniques providing high-accuracy solutions that are of potential use in tidal modelling, describes a trial of alternative GPS systems, and presents data examples from actual survey projects. Within the discussion the concept of accuracy versus precision is defined, with special emphasis on the problem of vertical datums.

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:

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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