Volumes I - V comprise the IOC Manual on Sea Level Measurement and Interpretation. Volume I (Basic Principles) was published in 1985 and is based on training courses held at the National Oceanography Centre (formerly Proudman Oceanographic Laboratory) on behalf of the PSMSL and IOC. It contains information on the scientific aspects of sea level change and on practical aspects of sea level measurement and data reduction. Volume II (Emerging Technologies) was published in 1994 and is complementary to the earlier volume, extending and updating the material on measurements.
In the late 1990s, it was realised that the contents of Volumes I-II were beginning to show their age and so Volume III was constructed and finally published in 2000. A much larger Volume IV followed in 2006, and Volume V was published in 2016 and focused on the use of radar gauges, but also contained updates to other areas. However, note that the earlier volumes are still useful, and still provide the basic sets of information for people intending to install and operate tide gauges.
Manuals I-IV are available in electronic form, while Volume V is still available in as a booklet. For the paper version of Volume V, email firstname.lastname@example.org. Electronic versions are provided in this directory as pdf files.
