“…Since marigrams sizes are relatively large, the resolutions chosen should be at least 300dpi but it can be adjusted depending on the original document size. For example, very large documents (several metres wide and more than 1 m high; the marigrams described in Talke, Familkhalili, et al (2020); Talke, Mahedy, et al (2020) were ~20 m in length) are scanned at resolutions of around 100dpi in order to make it further processable. This type of format complicates not only the scanning process – it is necessary to have the equipment to avoid paper undulations – but also the digitization because the digital file can be quite large and difficult to process.…”

“…The digitizer gets used to the writing style, but sometimes, there was more than one person with different handwriting. Therefore, the most common method of recovering data still entails the manual entering of water height values into a computer spreadsheet (Dangendorf et al, 2014; Pouvreau, 2008; Talke, Familkhalili, et al, 2020; Talke & Jay, 2017; Talke, Mahedy, et al, 2020).…”

“…The extension into the past of existing time series or the (re)discovery of new time series enables multiple types of oceanographic analysis. Historical sea level records can help constrain rates of changing sea levels and identify regions with local variability (Church & White, 2011; Hay et al, 2015; Hogarth, 2014; Jevrejeva et al, 2008; Talke et al, 2018; Talke, Familkhalili, et al, 2020; Talke, Mahedy, et al, 2020). Extended datasets can also be used to identify intra‐annual to decadal sea level variability (Dangendorf et al, 2013).…”

“…Anthropogenic coastal changes or changes in oceanic circulation and stratification can affect tidal characteristics (tidal range, harmonic components, tidal asymmetry, etc. ; Church & White, 2011; Familkhalili & Talke, 2016; Gouriou, 2012; Haigh et al, 2020; Jay, 2009; Li et al, 2021; Pineau‐Guillou et al, 2021; Ray, 2006; Ray & Talke, 2019; Talke et al, 2018; Talke, Familkhalili, et al, 2020; Talke & Jay, 2020; Talke, Mahedy, et al, 2020; Woodworth, 2010). For sites on tidal rivers, historical tide gauges can also help quantify historical river floods and flow statistics (Moftakhari et al, 2013, 2015, 2016; Talke, Familkhalili, et al, 2020; Talke, Mahedy, et al, 2020).…”

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.

Abstract. In the context of climate change, height and frequency variations of extreme sea levels (ESL) are studied using deterministic and probabilistic approaches. However, this type of approach does not highlight the dynamic effects (waves, currents) generated by meteocean events, beyond their effects on sea-levels. In particular, ESL estimates are certainly calculated by considering the main determining physical factors but cannot report on all the effects of these factors. Ultimately, this can lead to confusion between ESL and hazard. This article proposes a systemic assessment method to analyze coastal hazard changes at regional scales, integrating parameters influencing sea-levels, as well as factors describing the geomorphological context (length and shape of the coast, width of the continental shelf), meteocean events (storms, cyclones and tsunamis), and the marine environment (e.g., coral reef state and sea ice extent). French mainland and overseas territories were selected to apply the method. We have thus highlighted the need to study not only the sea-level variability, but also the current and future characteristics of meteocean events. The long, concave coasts bordered by a wide continental shelf appear particularly sensitive to variations in the intensity or trajectory of meteocean events. Coral reef degradation in the tropics and the decrease in seasonal sea ice extent in the polar regions can also significantly change the nearshore hydrodynamics and impacts on the shoreline. These results help to predict the types of hazard (shoreline erosion, rapid submersion and/or permanent flooding) that will increase the most in different coastal zones.
