“…But to return to Kircher, one aspect of tides for which he does deserve credit is his suggestion of the use of a float and stilling well for tidal measurements, a simple technology that remains in use at many locations around the world (Woodworth, 2022). A drawing can be found in Book 3 of the Mundus Subterraneus (Fig.…”

“…The objectives of this network were to meet hydrographic needs (datum definition) and to use sea level measurements to predict tides and construct tide tables. The development of a self-registering float tide gauge with stilling wells in the mid-19th century was a major technological improvement in water level measurements (Woodworth, 2021). Improvements continued in the 20th century with pressure and later radar tide gauge technology.…”

Coastal water level measurements represent one of the earliest geophysical measurements and allow an assessment of historical sea level rise and trends in tides, river flow and storm surge. However, recovery and digitization of archival tidal records have been much less widespread and systematic than, for example meteorological records. In this contribution, we discuss data rescue efforts and lessons learned in France, the United States and the United Kingdom, countries with early and extensive tide gauge networks by the mid-19th century. We highlight the importance of (a) cataloguing the historical gauge records, as a first step towards locating them; (b) locating data in archives, and then recovering and saving data by any means necessary, including photographs and scanning; (c) obtaining metadata, including both quantitative survey records, gauge checks and clock data, but also qualitative records such as gauge notes, letters and reports; and (d) quantitative statistical analysis of data and datum quality, using both standard data-entry checks but also tools that leverage the unique predictability of tide measurements. Methods for digitizing original analogue records are also discussed, including semi-automatic, computer-based methods of digitizing tidal charts (marigrams). Although the current best practice is described, future improvements are desirable and needed to make the more than estimated 10,000 station years of unused, undigitized records available to the scientific community.

“…In evaluating overall risk, coastal planners need to know the likelihood of flooding in addition to the value of assets and communities that may be affected. For instance, by analyzing extreme sea level distributions, planners can determine how often specific levels may be surpassed in any given year, representing the Return Period (or Average Recurrence Interval) for a particular level at a specific location (Woodworth 2022). As global sea level is expected to continuously rise beyond the end of this century (Fox-Kemper et al, 2021), this will lead to an increase of frequency and severity of ESL and coastal flooding, particularly in tropical regions (Oppenheimer et al, 2019).…”

This study examined extreme sea level (ESL) variations along the Malaysian coast using hourly sea level data from 17 tide gauge stations. The maximum observed ESLs varied from 1.26 m at Bintulu to 2.92 m at Port Klang, with tides playing a significant role in ESLs, especially along the west coast of Peninsular Malaysia. The spatial variation of seasonal ESLs showed a higher maximum of non-tidal residuals (0.8-1.1 m) along the east coast of Peninsular Malaysia during the northeast monsoon. This can be mainly attributed to the influence of the monsoon wind. Moreover, significant increases in ESLs were observed at 14 stations, largely due to rises in mean sea level. The interannual variability of ESL could be associated with the El Niño-Southern Oscillation at most sites except the northeast coast of Peninsular Malaysia. Interestingly, the interannual variability of the non-tidal residuals could be linked to the monsoon at sites located on the west coast of Peninsular Malaysia and East Malaysia. These findings provide valuable insights to relevant authorities for coastal planning, especially regarding flood risk management and the formulation of effective mitigation strategies.
