“…The robust link (in terms stationary running correlations) of high surges at Cuxhaven to the NSCI over time back to 1850 therefore suggests the homogeneity of the surge record, since both parameters (surge levels and SLP) are measured completely independently. Note that the high correlation between both can be taken as an independent measure of homogeneity in terms of low-frequency variability and long-term trends (e.g., Arns and Jensen 2010;Gouriou et al 2013), while a partial disagreement could be explained either by inhomogeneities or changes in wind circulation (e.g., direction). Such periods of disagreement are, however, not detectable in the presented time series.…”

The detection of potential long-term changes in historical storm statistics and storm surges plays a vitally important role for protecting coastal communities. In the absence of long homogeneous wind records, the authors present a novel, independent, and homogeneous storm surge record based on water level observations in the North Sea since 1843. Storm surges are characterized by considerable interannual-to-decadal variability linked to large-scale atmospheric circulation patterns. Time periods of increased storm surge levels prevailed in the late nineteenth and twentieth centuries without any evidence for significant long-term trends. This contradicts with recent findings based on reanalysis data, which suggest increasing storminess in the region since the late nineteenth century. The authors compare the wind and pressure fields from the Twentieth-Century Reanalysis (20CRv2) with the storm surge record by applying state-of-the-art empirical wind surge formulas. The comparison reveals that the reanalysis is a valuable tool that leads to good results over the past 100 yr; previously the statistical relationship fails, leaving significantly lower values in the upper percentiles of the predicted surge time series. These low values lead to significant upward trends over the entire investigation period, which are in turn supported by neither the storm surge record nor an independent circulation index based on homogeneous pressure readings. The authors therefore suggest that these differences are related to higher uncertainties in the earlier years of the 20CRv2 over the North Sea region.

“…This simulation didn't yield significantly different morphological changes of the sandbank, which would suggest that the use of such a ramp is a reasonable simplification. A negligible impact on the morphodynamic hindcast was also obtained concerning the sea level rise that took place between 1960 to 2000 (about +8.4 cm according to Gouriou et al (2013)). …”

Wave control on the rhythmic development of a wide estuary mouth sandbank: A process-based modelling study. Marine Geology, Elsevier, 2016Elsevier, , 380, pp.79 -89. 10.1016Elsevier, /j.margeo.2016 Wave control on the rhythmic development of a wide estuary mouth sandbank : a process-based modelling study AbstractThis study presents the numerical hindcast of the morphological changes and stratigraphy of a wide estuary mouth sandbank located along the French Atlantic coast (Marennes-Oléron Bay), and primarily investigates the respective contribution of tide and waves to its pluri-decadal evolution. Firstly, the morphodynamic hindcast appears strongly improved when tide and waves are considered in the forcing rather than only tide. Secondly, the modelling results suggest that the strong seasonal variation of the wave climate in this area explains the rhythmic lateral accretion of the bank (i.e. normal to the currents main direction) observed in seismic reflection profiles. The grain size variation in the area of sediment accretion is also characterized by a seasonal cycle. Finally, repetitive bathymetric surveys and seismic profiles revealed that the lateral accretion of the bank is associated with about one seismic reflector per year, which is in agreement with our modelling results when suggesting that these seismic reflectors are due to the seasonal variation of the grain size. These new results may be considered for the morphological evolution and the stratigraphy of other tidal sandbanks potentially affected by waves.

“…However, the scarcity of records covering more than 60 years limits our understanding of how sea level varies in the long‐term (Douglas, ; Zerbini et al, ). Long and reliable time series are available for the coasts of northern Europe (Holgate et al, ), and several studies rigorously evaluated historical time series worldwide (Araújo et al, ; Gouriou et al, ; Marcos et al, ; Raicich, ; Testut et al, ; Woodworth, ; Wöppelmann et al, ), partly including also coastal archeological data (Anzidei et al, ; Kayan, ; Lambeck et al, ; Toker et al, ). Unlike for the rest of Europe, it is difficult to obtain reliable long‐term gauging data for the eastern Mediterranean Basin (Woodworth et al, ).…”

A New Centennial Sea‐Level Record for Antalya, Eastern Mediterranean

Quantitative estimates of sea-level rise in the Mediterranean Basin become increasingly accurate thanks to detailed satellite monitoring. However, such measuring campaigns cover several years to decades, while longer-term sea-level records are rare for the Mediterranean. We used a data archeological approach to reanalyze monthly mean sea-level data of the Antalya-I (1935Antalya-I ( -1977 tide gauge to fill this gap. We checked the accuracy and reliability of these data before merging them with the more recent records of the Antalya-II (1985-2009) tide gauge, accounting for an eight-year hiatus. We obtain a composite time series of monthly and annual mean sea levels spanning some 75 years, providing the longest record for the eastern Mediterranean Basin, and thus an essential tool for studying the region's recent sea-level trends. We estimate a relative mean sea-level rise of 2.2 ± 0.5 mm/year between 1935 and 2008, with an annual variability (expressed here as the standard deviation of the residuals, σ residuals = 41.4 mm) above that at the closest tide gauges (e.g., Thessaloniki, Greece, σ residuals = 29.0 mm). Relative sea-level rise accelerated to 6.0 ± 1.5 mm/year at Antalya-II; we attribute roughly half of this rate (~3.6 mm/year) to tectonic crustal motion and anthropogenic land subsidence. Our study highlights the value of data archeology for recovering and integrating historic tide gauge data for long-term sea-level and climate studies.Plain Language Summary We demonstrate how data archeology of tide gauge data contributes to completing the contemporary century sea-level record in the eastern Mediterranean Basin. It is important to rescue such data and to make them available for future research on sea-level rise that goes beyond modern and highly accurate satellite-based monitoring. In our particular case, the monthly mean sea-level records of Antalya-I (1935Antalya-I ( -1977, we merged them with the modern records of Antalya-II (1985-2009) located only~5 km away. This merger offers a homogeneous composite time series of monthly and annual mean sea level of nearly 75 years, the longest record in the eastern Mediterranean Basin. We reviewed all previous work, metadata, and changes in the zero of tide gauges and datum. Major issues included obtaining the leveling information and to determine rates of tectonic vertical crustal movement. It is worth noting that nearly half of the observed sea-level rise in Antalya-II is driven by local vertical land motion, which might be influenced heavily by anthropogenic sources.
