Spurious Long-Period Tides Due to Tide Gauge Errors

Abstract

A combination of tide height errors, and resetting the gauge height to a staff reading at a fixed hour each day, can lead to spurious long-period signals in series of hourly tide heights. These signals can be of the same order as the fortnightly tides. The problem is discussed in relation to the tides at Sydney (Australia), where it is believed to be responsible for an anomalous Msf tide of amplitude 0.5 cm.

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Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form.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