“…The shallow northern Adriatic Sea is the Mediter-ranean sub-basin where storm surges reach higher values (Marcos et al, 2009), mainly triggered by a strong southeasterly moist and warm wind, called sirocco. For this reason, in this area storm surges and waves have been deeply investigated in the past (Orlić et al, 1992;Bajo and Umgiesser, 2010;Cavaleri et al, 2010;Lionello et al, 2012;Medugorac et al, 2015;Ferrarin et al, 2017;Pomaro et al, 2017;Vilibić et al, 2017;Bajo et al, 2019;Ferrarin et al, 2019). Tidal dynamics are particularly evident in the northern Adriatic Sea, where the most energetic tidal constituents, the semi-diurnal M 2 and the diurnal K 1 , reach amplitudes of 27 and 18 cm, respectively (Ferrarin et al, 2017).…”

“…The water levels along the coast can be estimated by numerical models and combined with a digital elevation model (DEM) for forecasting inundation intensity and extent. Several methodologies have been developed and applied at the basin and local scales for estimating hazard maps for coastal flooding (Hinkel et al, 2014;Vousdoukas et al, 2016;Wolff et al, 2016;Ferreira et al, 2017;Rizzi et al, 2017;Armaroli and Duo, 2018). It must be taken into account that meteorological and ocean models provide just an approximation of reality, despite their continuous development and improvements.…”

Abstract. Addressing coastal risks related to sea storms requires an integrative approach which combines monitoring stations, forecasting models, early warning systems, and coastal management and planning. Such great effort is sometimes possible only through transnational cooperation, which becomes thus vital to face, effectively and promptly, the marine events which are responsible for damage impacting the environment and citizens' life. Here we present a shared and interoperable system to allow a better exchange of and elaboration on information related to sea storms among countries. The proposed integrated web system (IWS) is a combination of a common data system for sharing ocean observations and forecasts, a multi-model ensemble system, a geoportal, and interactive geo-visualisation tools to make results available to the general public. The multi-model ensemble mean and spread for sea level height and wave characteristics are used to describe three different sea condition scenarios. The IWS is designed to provide sea state information required for issuing coastal risk alerts over the analysed region as well as for being easily integrated into existing local early warning systems. This study describes the application of the developed system to the exceptional storm event of 29 October 2018 that caused severe flooding and damage to coastal infrastructure in the Adriatic Sea. The forecasted ensemble products were successfully compared with in situ observations. The hazards estimated by integrating IWS results in existing early warning systems were confirmed by documented storm impacts along the coast of Slovenia, Emilia-Romagna and the city of Venice. For the investigated event, the most severe simulated scenario results provide a realistic and conservative estimation of the peak storm conditions to be used in coastal risk management.

“…Tidal ranges in the region are microtidal, increasing as water depth decreases to the north (Cushman-Roisin and Naimie, 2002). The influence of strong northeasterly Bora and south-easterly Sirocco winds can significantly alter the tidal regime (Orli c et al, 1994;Vilibi c, 2006;Ferla et al, 2007) and meteorological tsunamis associated with prolonged low atmospheric pressure systems are a relatively common occurrence (Vilibi c;Sepi c, 2009;Vilibi c et al, 2017). Instrumental observations of RSL change from long-term (>50 years) tide-gauge stations in the Adriatic are restricted to the northern and eastern coastline (Fig.…”

Differential tectonic activity is a key factor responsible for variable relative sea-level (RSL) changes during the late Holocene in the Adriatic. Here, we compare reconstructions of RSL from the central-eastern Adriatic coast of Croatia with ICE-7G_NA (VM7) glacial-isostatic model RSL predictions to assess underlying driving mechanisms of RSL change during the past~2700 years. Local standardized published sea-level index points (n ¼ 23) were combined with a new salt-marsh RSL reconstruction and tide-gauge measurements. We enumerated fossil foraminifera from a short salt-marsh sediment core constrained vertically by modern foraminiferal distributions, and temporally by radiometric analyses providing subcentury resolution within a Bayesian age-depth framework. We modelled changes in RSL using an Errors-In-Variables Integrated Gaussian Process (EIV-IGP) model with full consideration of the available uncertainty. Previously established index points show RSL rising from À1.48 m at 715 BCE to À1.05 m by 100 CE at 0.52 mm/yr (À0.82-1.87 mm/yr). Between 500 and 1000 CE RSL was À0.7 m below present rising to À0.25 m at 1700 CE. RSL rise decreased to a minimum rate of 0.13 mm/yr (À0.37-0.64 mm/yr) at~1450 CE. The salt-marsh reconstruction shows RSL rose~0.28 m since the early 18th century at an average rate of 0.95 mm/yr. Magnitudes and rates of RSL change during the twentieth century are concurrent with long-term tide-gauge measurements, with a rise of~1.1 mm/yr. Predictions of RSL from the ICE-7G_NA (VM7) glacial-isostatic model (À0.25 m at 715 BCE) are consistently higher than the reconstruction (À1.48 m at 715 BCE) during the Late Holocene suggesting a subsidence rate of 0.45 ± 0.6 mm/yr. The new salt-marsh reconstruction and regional index points coupled with glacial-isostatic and statistical models estimate the magnitude and rate of RSL change and subsidence caused by the Adriatic tectonic framework.

“…Due to the discontinuous nature of the monthly measurements (X t ) used in this study, the removal of the annual cycle from the time series via a classical Fourier analysis or a low-pass filter could not be directly applied. The annual cycle (S t ) was thus obtained with a general harmonic regression model (Chatfield, 2004;Wilks, 2011) applied to the de-trended signal (Y t = X t − T t − µ t , where T t and µ t are respectively the linear trend and the mean estimated for the raw signal X t ) and using cosine and sine functions for two Fourier frequencies…”

Abstract. The paper documents seasonality, interannual-to-decadal variability, and trends in temperature, salinity, and density over a transect in the shallow northern Adriatic Sea (Mediterranean Sea) between 1979 and 2017. The amplitude of seasonality decreases with depth and is much larger in temperature and density than in salinity. Time series of temperature and salinity are correlated in the surface but not in the bottom layer. Trends in temperature are large (up to 0.6 ∘C over 10 years), significant through the area, and not sensitive to the sampling interval and time series length. In contrast, trends in salinity are largely small and insignificant and depend on the time series length. The warming of the area is more during spring and summer. Such large temperature trends and their spatial variability emphasize the importance of maintaining regular long-term observations for the proper estimation of thermohaline trends and their variability. This is particularly important in regions which are key for driving thermohaline circulation such as the northern Adriatic, with the potential to affect biogeochemical and ecological properties of the whole Adriatic Sea.
