“…Coor et al, 2009;Migeon et al, 1998;Scott et al, 2003). Statistical analyses can be used to select relevant indicators to characterize marine deposits made by storms (Pouzet et al, 2019). Marine flooding is identified by a typical sedimentary sequence that alternates between a level of marine sand (the washover fan) and the lagoon layers surrounding composed of vases or silts with continental chemical influence.…”

“…Strontium (Sr) and Calcium (Ca) are the two elements which are mostly cited as marine (e.g. Chagué- Goff et al, 2017;Pouzet et al, 2019;Roy et al, 2010). Other possibilities of marine proxy are also mentioned in bibliography, including foraminifera (e.g.…”

“…Grain size and elemental analyses are also measured with a Malvern Mastersizer 2000 © particle size analyzer, and a Avaatech© X-ray fluorescence (XRF) core scanner (Bouchard et al, 2011;Gee and Or, 2002;Martin et al, 2014). Marine geochemical ratios, extracted from a statistical study, are used (Pouzet et al, 2019). As a positive correlation between lightness and carbonate content has already been demonstrated (Mix et al, 1995), lightness is estimated by colorimetric analyses with a…”

“…Once the marine layers are detected, they can be linked to extreme events or precise past storms thanks to historical archives (Figure 3) if the region has a dense historical documentation (Liu et al, 2001). Numerous types of documents, such as ancient maps, narrative sources (chronicles, diaries or memories) and documents preserved in libraries and in regional archives (books of accounts, records of repairs, surveys conducted after a disaster, barometric observations, newspapers for instance) can be used (Athimon and Maanan, 2018;Pouzet et al, 2019). They expose observational and descriptive data on past extreme weather hazards such as the descriptions of the storm and the damage caused, as well as impacts on societies and their reactions and adaptation (Garnier et al, 2018;Sarrazin, 2012;Sauzeau, 2014).…”

This paper presents the benefits of multiplying environmental indicators to better understand the impacts of past storm events on the environment. It aims to describe the methodological approaches used to reconstruct past extreme events from washover deposits, at the three main temporal scales used in scientific bibliography: i) the long timescale (Holocene, since 12 000 years BP), ii) the meso timescale (for the last millenary) and iii) the short timescale (Anthropocene, for the last centuries). This methodology is based on a "multiproxy" analysis using sedimentology, geochemistry and various methods of isotope dating. Linking these methods with other disciplines such as history, archaeology and meteorology leads us to confirm with great certainty the existence of these extreme events, and to expose their impacts on the environment and on past coastal societies. These different approaches enable us to enhance and refine our knowledge of coastal hazards, but also to apprehend possible storm influences in the context of climate change.

The use of historical sources and data to improve knowledge of past extreme events is no longer to be demonstrated. Old quantitative and qualitative data on water levels available in non-digitized tidal charts, tide gauge records, newspapers, city council registers, engineers' reports, etc. can be used to reconstruct water levels and skew surges that occurred during a storm. Data from primary and/or secondary historical sources require a historical critical approach. This paper presents an interdisciplinary study that required a combined work between historians, geographers, geologists and engineers. In this study, nine different variables that can lead to uncertainties on the quantification of historical skew surges have been identified , such as tidal predictions, chart datum references or the reliability of the historical data. Starting from the historical critical method developed by historians over decades, we propose a three-step method to assess the quality of historical documents and define their level of reliability. The method is applied to two case studies: the storm of 16 th November 1940 and the storm of 15-16 th February 1941. Interesting results are provided and the study shows that by paying attention to the potential causes of uncertainties, by ensuring the reliability of historical sources and data through the use of the historical documents quality method, by deepening historical researches and by combining different scientific fields and methods, it is possible to reduce uncertainties and errors when quantifying historical skew surges.
