  • Estimation of Sea Level Rise and Storm Surge Risks Along the Coast of Estonia, Baltic Sea – a Tool for Coastal Management
    Littoral 2010, 12005 (2011) DOI:10.1051/litt/201112005 © Owned by the authors, published by EDP Sciences, 2011 Estimation of sea level rise and storm surge risks along the coast of Estonia, Baltic Sea – a tool for coastal management Ülo Suursaar, Estonian Marine Institute, University of Tartu, [email protected] Jaak Jaagus, Institute of Ecology and Earth Sciences, University of Tartu, [email protected] Tiit Kullas, Estonian Marine Institute, University of Tartu, [email protected] Hannes Tõnisson, Institute of Ecology at Tallinn University, [email protected] Abstract The aim of the paper is to present statistical analysis of the sea level data obtained from the Estonian coastal tide gauges over the period 1842–2009, to assess storm surge risks and to discuss climate change related mitigation and management issues in the coastal zone of Estonia. Long-term variations of both mean and extreme sea level values were studied in the Eastern section of the nearly tideless Baltic Sea. Influenced by postglacial land uplift, the series of relative sea level displayed slightly varying trends. The remarkably steep rise in annual maximum sea levels (2–12 mm/yr) could be explained by the local response to the changing regional wind climate. Due to its windward location, the sea level variations in the semi-enclosed study area are sensitive to the changes in cyclonic activity. Maximum value analysis revealed that in case of the south-westerly exposed Pärnu Bay, two storm surge events (253 in 1967 and 275 cm in 2005) were inconsistent with the theoretical distributions, which indicate that, in some locations, the most extreme sea level events are hardly predictable by means of return statistics.

Boreal Env. Res. 25: 51–63. A combination of statistical and deterministic methods was used to calculate the flood level for the Hanhikivi peninsula on the northeastern coast of the Gulf of Bothnia, where a nuclear power plant is planned. An existing Baltic Sea numerical model (BSM-2010) solv- ing the depth-averaged shallow water equations was used. Using formulas for an idealized storm field, wind and atmospheric pressure fields were assigned as forcing. The possible intensity of the extreme storm field was determined from the database of storm fields that passed over the northern hemisphere from 1958–2016. The modeling results show that the maximum water level rise at Hanhikivi occurs when an extreme storm field over south- ern Norway moves east-northeast with a velocity of 65 km h–1. Extreme water levels in Hanhikivi obtained with statistical and deterministic methods at a probability up to 0.01% (return period of 104 years) are +252 cm and –251 cm, respectively.

  • Pumice in the North Atlantic
    Ocean-transported pumice in the North Atlantic Anthony Newton PhD University of Edinburgh 1999 Declaration I, Anthony Newton hereby declare that the work contained herein is my own and has not previously been presented for examination. Any contributions by others is acknowledged in the text. September 1999 ii For Keith Newton 1930-1984 iii “Some days we would pass through pumice lying in ridges, each piece uniformly the size and appearance of a bath sponge, then again we should pass through perfect fields of small yellow pumice spread evenly over the surface just for all the world like a green field of grass covered all over with buttercups, and the undulation of the swell of the trade wind produced an indescribably pretty appearance.” (Reeves, 1884). iv Abstract The overall aims of this study are to identify the sources of the widespread Holocene pumice deposits found along the coasts of the North Atlantic region and establish the ages of the source eruptions. In order to tackle this, it is necessary to determine whether it is possible to “fingerprint” the pumice of individual eruptions and link ocean-transported material with the established tephrochronological framework based on the stratigraphy of airfall deposits. Over 1500 electron probe microanalyses and over 200 Secondary Ion Mass Spectrometry analyses have been undertaken on pumice and tephra samples. These are the first high quality grain specific analyses carried out on ocean-transported pumice in the North Atlantic. Current knowledge of the extent of pumice distribution in the North Atlantic region is assessed for both shoreline (natural) and archaeological contexts.

  • Inverse Gaussian Distribution of Wave Set-Up Heights Along a Shoreline with Complicated Geometry
    Earth Syst. Dynam. Discuss., doi:10.5194/esd-2016-76, 2017 Manuscript under review for journal Earth Syst. Dynam. Published: 31 January 2017 c Author(s) 2017. CC-BY 3.0 License. Inverse Gaussian distribution of wave set-up heights along a shoreline with complicated geometry Tarmo Soomere1,2, Katri Pindsoo1 1Laboratory of Wave Engineering, Institute of Cybernetics at Tallinn University of Technology, Akadeemia tee 21, Tallinn, 5 12618, Estonia 2Estonian Academy of Sciences, Kohtu 6, Tallinn, 10130, Estonia Correspondence to: Katri Pindsoo ([email protected]) Abstract. The phenomenon of wave set-up may substantially contribute to the formation of devastating coastal flooding in certain coastal sections. We study empirical probability distribution of the occurrence of different set-up heights in section of 10 coastline near Tallinn in the Gulf of Finland, the eastern Baltic Sea. The shoreline in the study area is often attacked by high waves from various directions and also has a complex geometry. Shown is that this distribution substantially deviates from the Rayleigh or the Weibull distribution that usually reflect the distribution of different wave heights. The distribution of wave set-up heights matches a Wald (inverse Gaussian) distribution along the entire study area. Even though different sections of the study area are open to different directions and host substantially different wave regimes, the leading term of 15 the exponent in the associated inverse Gaussian distribution varies insignificantly along the study area and generally is close to –1. This appearance signals that extreme set-up events are substantially more probable that it could be expected from the probability of occurrence of severe seas.

Laurila and Antti Mäkelä Title Review on winds, extratropical cyclones and their impacts in Northern Europe and Finland Abstract Strong winds caused by powerful extratropical cyclones are one of the most dangerous and damaging weather phenomena in Northern Europe. Stormy winds can generate extreme waves and rise the sea level, which leads occasionally to storm surges in coastal areas. In land areas, strong winds can cause extensive forest damage. In general, windstorms induce annually significant damage for society. Moreover, due to climate change, the frequency and the impacts caused by the windstorms is changing. In this report, we introduce a literature review on the occurrence of strong winds, extratropical cyclones and their impacts in Northern Europe. We present the most important findings on both past trends and current climate on wind speeds and extratropical cyclones based on in-situ measurements and reanalysis data. We also briefly analyse impacts caused by extreme convective weather. Furthermore, we aim to respond to the question on how the wind climate in Northern Europe is going to change in the future under climate change.

  • Extreme Wave and Water Level Conditions in the Baltic Sea in January 2005 and Their Reflection in Teaching of Coastal Engineering
    Extreme wave and water level conditions in the Baltic Sea in January 2005 and their reflection in teaching of coastal engineering Tarmo Soomere, Department of mechanics and Institute of Cybernetics at Tallinn University of Technology (email: [email protected]) Terry Healy, University of Waikato (email: [email protected]) Abstract Windstorm Gudrun (January 7–9th 2005, also known as Erwin in some countries) was one of the strongest storms in the Nordic Region of Europe during the last decades. It caused widespread property damage, exceptionally high storm surge levels, and the loss of 18 lives. The storm surge in the Estonian city of Pärnu at the eastern coast of the Baltic Sea reached 275 cm above mean sea level, which is the highest flood ever recorded since regular measurements started in 1824. Extremely rough seas occurred in the north-eastern region of the Baltic Sea. The overall maximum significant wave height was estimated to be about 9.5 m off the coasts of Saaremaa and Latvia. Such wave conditions are extremely rare in this water body. Despite several atypical features of this storm, the reaction of water masses was reasonably forecast 48–54 hours ahead and accurately reproduced in 24–36 hour forecasts in the leading operational oceanographic centres. The lessons learned from this event led to re-launching of routine operational oceanographic services in Estonia and were used in regular courses for students specialising in port and coastal engineering in Tallinn University of Technology, and for students in hydrography at the Estonian Marine Academy a few weeks after the events.
