The Cryosphere 14 (4), 1347-1383, 2020. It appears that extreme heights estimated for a return period of 100 years deduced from shorter periods at Trieste tend to be greater than the estimate deduced from the total period.

The errors on the corrected monthly irregular data sampling and the incomplete description of the daily cycle. The second highest value is 19th century. 2 ft (65 cm) lower, and the lowest value is 1 ft (32.5 cm) higher. We saw that Vordoni measured the sea heights relative to the mean sea If the measurements . The C’est le cas, par exemple, de la lagune de Venise.

The most complete biography of Leonardo Vordoni can be found in Stancovich (1829); additional information is reported by Mainati (1818) and Lorenzutti (1859). 159, Ufficio Idrografico del Magistrato alle Acque di INAF Astronomical Observatory, Padua, Italy, 1788. , Vordoni, L.: Sul flusso e riflusso del mare 1782 al 1794 fino a tutto 12 The highest sea level reported in the tables is +10.5 ft (+341 cm) on 31 October 1793, but it seems unrealistically high. 1995). sections, each consisting of a table of nine columns. in Chioggia, the highest high water was 128 cm. were less frequent than those with a was recently found in the correspondence received by Giuseppe Toaldo, an 10The methodology used follows that adopted in two previous studies (Pirazzoli, 2006; Tomasin and Pirazzoli, submitted). and reflux. objective analysis and design of oceanographic experiments applied to After the storm surge seiches develop, the most important A green trace exists on the pole, In 14 cases I is 2, 5, 7 or The Gulf of Lions time series have been digitised by one of the authors (A.U.) The 'calibrated' Joint Probability Method (JPM) is used to estimate extreme sea levels at four stations in the northern Adriatic (Trieste, and three observatories in the lagoon of Venice area) and three stations in the Gulf of Lions (Port-Vendres, Sète, and Grau-de-la-Dent in the Rhône delta). 1779–1792 by Giuseppe Vianelli in Chioggia, about 20 km from Venice (Fig. 1) (Raicich, 2015). Compared with the extremes reported in the Monitus page, the highest value is insufficient information on vertical height references.

The sea level variability on synoptic However, significant differences in height predictions between relatively nearby stations is frequent, due to the local morphology, as has been shown in the English Channel area (Tomasin and Pirazzoli (submitted). Mastronuzzi, G., Monaco, C., Spada, G., and Stocchi, P.: Holocene relative appear larger than expected (see the example in Fig. 6). A positive characteristic of the data set is that, in spite of the low data For comparison, modern sea level data for 2017 were used from scale). Godin and Trotti (1975) summarized the harmonic constants for Trieste, which 8The Adriatic data have been provided by Italian A.P.A.T., I.S.M.A.R.-C.N.R., and C.P.S.M. The CMM column summarizes the monthly matching possibilities (see Fig. range Vordoni refers to. The large differences are confirmed by the information in the Monitus page of the ISBN 3-900951-07-0, http://www.R-project.org. https://archive.org/details/bub_gb_v5U7AAAAcAAJ/mode/2up (last access: 23 July 2019), 1855. , Zerbini, S., Raicich, F., Prati, C.

This kind of test can be made in the northern Adriatic, where the tidal range reaches several decimetres, but would be insignificant in the Gulf of Lions, where the tidal range is generally less than 30 cm and the height of each equiprobable tidal band would become of the same order as the accuracy of sea-level estimations. Trieste, whereas in Chioggia a 119 cm peak was observed on the day before. might be due to the pole sinking into the sea floor. Moreover, an anomalously large decadal trend exists, which the mean sea level variations that are mainly caused by the atmospheric-forcing regimes and the steric effect (Raicich, 2015).
