Manual on sea level measurement and interpretation. Volume IV - An update to 2006.

Abstract

This is the fourth in the series of IOC Manuals on Sea Level Measurement and Interpretation. It incorporates the changes in tide gauge technology and measurement techniques in the five years since the third manual was written, and includes material from the Workshop on New Technical Developments in Sea and Land Level Observing Systems (UNESCO, Paris, 14–16 October 2003). In addition, it reflects to a great extent the changes in priorities for tide gauges in a global network which have taken place in recent years. For example, it is inconceivable now that most gauges installed in the GLOSS network will be without a real-time reporting capability and a capacity to provide data of use to a tsunami warning system.The manual includes some sections of text from the earlier editions, updated as appropriate. However, for reasons of space it does not include some other sections from the earlier versions, even though they are still valid and useful (e.g. the discussion of data quality control and filters in Volume III, see the present Appendix II). The earlier editions continue to be readily available on the web at http://www.pol.ac.uk/psmsl/manuals/
