Die Untersuchungen konzentrieren sich auf große Ereignisse, wie beispielsweise Erdbeben an Plattengrenzen und damit verbundene Tsunamis, ein plötzlicher Meeresspiegelanstieg, Flutereignisse oder Stürme. Das interdisziplinäre Wissenschaftlerteam untersucht dabei die Auswirkungen auf die Küstenzone und entwickelt – nach Analyse vergangener, aktueller und zukünftiger Ereignisse - mögliche Anpassungsstrategien in Bezug auf Naturgefahren an den Küsten.
Erfahrungen in jüngster Vergangenheit haben gezeigt, dass die Auswirkungen von ozeanischen Gefahren, wie Erdbeben an Plattengrenzen, Vulkanausbrüchen oder Hangrutschungen an den Küsten und die durch sie ausgelösten Tsunamis, völlig neue Dimensionen erreichen und die mit klassischen Risikoanalysen angenommenen Schadensausmaße deutlich überschritten werden. Diese neue Kategorie von Bedrohungen (z.B. das Sendai-Ereignis 2011 in Japan) ist oft die Folge einer Kette sich verstärkender Katastrophen und kann unmittelbare Auswirkungen auf die eng verwobene globale Gesellschaft und Weltwirtschaft haben. Die Ereignisse bedrohen Küstenregionen mit großer Bevölkerungsdichte und sensiblen Industrieanlagen, die bereits heute mit den Folgen des globalen Wandels konfrontiert sind. Zu diesen Folgen zählen der Meeresspiegelanstieg, der schnelle Küstenrückgang, Delta-Absenkungen, Sedimentsenken im Oberlauf der Flüsse und starke Stürme. Die integrierte multidisziplinäre Forschung umfasst die Küstenzone, den Schelf und den Kontinentalhang, mit dem Ziel, die gesamte Wirkkette von physikalischen Statusänderungen am Meeresboden bis hin zu den Konsequenzen an den Küsten zu untersuchen.
Zentrale Themen sind:
- Untersuchung des Meeresbodens im Hinblick auf seismische Ladung in ausgewählten Erdbeben-Entstehungsregionen und auf Hangstabilität in rutschungsgefährdeten Arealen.
- Erforschung der Veränderungen in Deltas, die durch langsame Prozesse, wie Sedimentverlagerungen oder Grundwasserentnahmen, und kurzfristige Extremereignisse, wie Tsunamis, entstehen, um den Gefahren besser begegnen zu können.
- Entwicklung einer Beurteilungsmethode für die Küstengefahren, die mehrere Gefahren einbezieht, um langfristige Politik- und Managemententscheidungen zu unterstützen.

Deltaic coasts endangered by riverine sediment trapping Example of the Sao-Francisco delta (Brazil)
The economic development of the São Francisco River basin, the largest one along the North-Eastern coast of Brazil, has increased by building a series of seven river-dams since the 1950s. After the construction of the last dam (Xingó), strong coastal erosion, reaching maximum rates of 98.6 m/year, has been recorded at the river mouth (Bittencourt et al., 2007), also leading to the destruction of the coastal village Cabeço (Fig. 1). Therefore the São Francisco deltaic coast serves as a good example to prove the impact of sediment trapping. Collaboration with Brazilian colleagues from Salvador and Natal Universities already exists, working together in a DFG-funded programme. From calculations of dune migration rates, it has been derived, that sediment transport is reduced by discharge regulation. This also goes along with a strengthening of the tidal effect (Traini et al., accepted). Further, changes of the tidal impact lead to water circulation patterns, which are most typical for salt-wedge estuaries with occurrence of clear flocculation processes (Traini et al., 2011). There is indication, that the currently ongoing hydrodynamic and sedimentary processes are linked to anthropogenic impact. Again, there are still unanswered questions: - What is the sediment volume retained by the Xingó-dam?- What is the annual amount of sediment reaching the river-mouth as bed-load and/or suspendedload? To answer the these questions, information on the sediment architecture and thickness as well as on the sediment composition and spatial distribution of the Xingó-dam reservoir infill is needed for calculating the volume and origin of sediment retained by the dam. Detailed data sets of changing river-bed morphology will provide information for quantifying bed-load transport downstream the dam and at the river mouth (including tidal impact). Simultaneously, suspended load will be quantified by measuring suspended particulate matter amount and composition, especially at the river-mouth, where currently estuarine processes occur (Traini et al., 2011). The results of this study will strongly support the goal of answering questions on sinking deltas related to forcing factors, as asked by the Phase II of the Cluster of Excellence. They will explain a part of the causes and effects that lead to changing and vulnerable coastal systems.
Seismogenic faults, landslides, and associated tsunamis off Southern Italy contributing to the research topic From ocean hazards to coastal preparedness
Dr. Felix Gross,
Southern Italy is located at a continental margin, which is associated along converging plate boundaries. Hence the area is strongly affected by seismicity and volcanic activity. Within historical and modern times the coastline of southern Italy experienced severe earthquakes, landslides and tsunamis. Three major earthquakes took place in 1693, 1783 and 1908 (Billi et al. 2010), in which the 1908 earthquake (Ms=7.3 80,000 casualties) was characterized by the worst tsunami Italy documented in historical times (~2000 casualties). However, it is still unclear, whether the tsunami was triggered by a sudden vertical movement along a major fault during the earthquake or as a result of giant marine slide initiated by the earthquake. The recurrence rates of major landslides and therefore the risk associated with landslides is also unknown. Based on detailed bathymetric data sets collected by Italian colleagues in the frame of the MaGIC Project (Marine Geohazards along the Italian Coast) an acquisition of seismic data (2d and 3d) and gravity cores shall be collected off Southern Italy during the RV Meteor Cruise M86/2 scheduled for 27.12.2011-17.01.2012. Earthquakes, Landslides and tsunamis are a major threat for all coasts surrounding the Mediterranean Sea detailed investigations of these major catastrophic events are the basis for assessing the related risks for the coasts. The coast of Southern Italy represents an outstanding location for such investigations due to regular well documented catastrophic events in historic times. Hence the proposed work would represent an important step towards a risk assessment for the entire Mediterranean Sea.
Shoreline changes at Macaneta Peninsula, Mozambique and mitigation alternatives
The change in shoreline is mainly associated with waves, tides, winds, periodic storms and sea level change. Activities that can result in coastal modification such as the shift from agriculture to semi-industrial and industrial activities, sand extraction, building along the coast, dam construction, and river divergence can accelerate erosion and affect the sediment budget. The proposed study aims at investigating the problem of shoreline changes at Macaneta Peninsula, Mozambique, using oceanographic, meteorological and other relevant datasets to establish the root causes of observed shoreline changes. The study also intends to use a multidisciplinary approach (combine both natural and social sciences subjects) to investigate socio-economic impacts of shoreline changes, and propose better solutions for the required adaptation or mitigation strategies. This study integrates research areas of ocean hazards, sea level rise and coasts at risk. In addition, the research relies on various areas of knowledge, from natural sciences to social sciences, making use of oceanographic, meteorological and hydrodynamic data, and relating them with socio-economic and environmental issues.
Salt marsh development under the influence of decadal and climate variations
Dr. Mark Schürch,
With the proposed project, I intend to investigate the relative influence of storm activity and changes of river discharge as a consequence of climate change and decadal climate variations (e.g. El Niño) on the long-term evolution of estuarine/deltaic salt marshes. Based on the hypothesis, formulated by Kolker et al. (2009) and Schuerch et al. (2012b), I will further assess whether the influence of increased storm activity and variations of river discharges is more pronounced on salt marshes in micro-tidal environments than on salt marshes in macro-tidal environments.
Next Generation Interactive Scientific Poster
Prof. Tom Duscher,
Is the classical, printed poster still the ideal way to convey scientific information? The classical poster does often not offer enough space for the sheer complexity of the contents – texts, pictures, graphs and tables – used to convey scientific research today which causes inability to communicate contents and statements concisely. The classical poster also lacks an appropriate possibility for continuous updates which are necessary to include newer research results and would do justice to today‘s constant changes of information. Therefore, comprehension and the range of research results decrease, which raises the question of whether the classical poster can still function as an adequate and contemporary medium for the illustration and communication of scientific content. Our aim within the framework of this research proposal is to evaluate, if the poster as a classical scientific medium can be extended by digital and interactive elements in order to correspond to the demands of attractive formats for the mediation of scientific content these days. A working prototype (demonstrator) of the semester topic 2013:”Submarine landslides / Tsunamis” will be conceived, designed and programmed. This research proposal forms the basis of a conceptual investigation of a semester project at the Muthesius Academy of Fine Arts and Design in 2012. The subjects of the research are immersive interaction concepts and successive mediation of scientific knowledge on the basis of non-linear narration.
Significance and danger of normal faulting in accretionary subduction zones
Dr. Jacob Geersen,
The giant 2010 Chile and 2011 Japan earthquakes ruptured well-known plate-boundaries where their occurrence is expected. What took the scientific community by surprise in both cases were large-magnitude (~Mw=7.0) extensional aftershocks that nucleated on upper-plate normal faults above the seismogenic zone. Although these aftershocks seem to relate to the subduction process, little is yet known about their role in the earthquake cycle or the danger that emanates from them. Where the seismogenic zone extends to shallow depth (Cascadia, Makran) similar aftershocks and associated normal-faults would be located offshore within the gas-hydrate stability field. Their sheer existence and possible seismic activation in an area of gashydrates incidentally provokes questions regarding venting of gas-hydrate after megathrust earthquakes or the danger that they pose on seabed infrastructure related to a possible future exploitation of gas-hydrates. There seems no doubt that for a comprehensive assessment of the geo-hazard in a convergent plate margin the understanding of the role of upper-plate normal faults is fundamental, but lacking behind. This project will help closing this gap in knowledge by studying such normal-faults from different accretionary margins using multi-frequency marine acoustic and seismological data combined with tsunami and earthquake magnitude modelling. The output will advance our understanding of the marine-hazard caused by extension in accretionary subduction zones (key aspect in R06), improve hazard assessments and mitigation efforts in areas where active normal-faults are present (relevant for R02) and inform decision making related to possible exploitation of marine gas-hydrates in actively deforming accretionary margins (relevant for R03).
Crowd Science from Coast to Coast
Dr. Jörn Schmidt,
Global assessments of vulnerability to climate-change induced sea-level rise and of its associated impacts are impeded by the severe lack of information on coastal physical characteristics. We propose the development of a crowd science framework that enables contributors to collect and transmit information and data on coastal physical and geomorphological characteristics and coastal types. Furthermore, we aim to expand the scope of the proposed framework for the purpose of climate change communication, and specifically for raising awareness regarding related risks and opportunities in coastal regions. The acquired data will be included in a spatial database, which will support the application of integrated assessment models. The framework will initially be developed for a pilot application for the Mediterranean basin and, if successful, will be extended to global scale. We envisage the framework to also be transferable to other sectors or themes, such as fisheries or marine resources.
The Future Ocean: A spatial audiovisual installation projecting the future of the oceans within an abstract soundscape
Dr. Nicolaas Glock,
Science influenced contemporary art and musical composition in many different facets, while the artistic presentation has led to new social and cultural perceptions about science[1]. Varese was inspired by processes like crystal growth, while Xenakis based his music on stochastic events. As a transdisciplinary artistic research project we propose to create an audiovisual installation based on projections about the future ocean focusing on sea level rise. Within the context of the “Wissenschaftsjahr der Ozeane 2016/17” this project acts within a good time frame for public debate. The sonic part of the installation will be based on concrete recorded sounds from the ocean and, respectively, oceanic research. These sounds will be used for asymmetric granular synthesis and other modular sound manipulations to create an abstract spatial soundscape. The whole project will be implemented in two parts: 1.: Development and presentation in the wave field synthesis laboratory at the centre for microtonal music and multimedia in Hamburg (Hochschule für Musik und Theater) and 2.: The creation of a new audio-visual installation in Kiel. Wave field synthesis can create virtual sound sources by producing wave fronts synthesized by a large number of individually controlled loud speakers. These virtual sound sources are independent from the position of the listener, e.g. a listener can walk around or through a virtual sound source. Sea level rise will be simulated by gradual filling of the room with “soundgrains” using granular synthesis, resulting in a gradual sound immersion of the recipient. Ocean acidification might be simulated by representing H3O+ ions with “soundgrains” which are stochastically distributed within the room and raise their concentration according to predicted future pH changes. Temperature changes might be represented by changes in pitch and spatial velocity of the sounds. After the realization of the project and presentation in the wave field synthesis lab the sonic part will be compiled to an installation in Kiel which will create a spatial sound field by the distribution of several loud speakers, using concrete instead of virtual sound sources. The visual part of the installation will support the soundscape and be created by the Muthesius Academy of Arts under supervision of Prof. Tom Duscher. With the use of projection mapping and sensors visual representations of the data will be projected into the special installation. While the visitor enters the installation the projection and sound will react to his movement. The presence of the visitor will interact with the environment as a metaphor of the real life relationship between men and nature. Visual elements can include maps of sea-level rise scenarios at different temporal and spatial scales photographs or movies of ice-sheet melting or graphs and maps of coastal population distribution and its responses to changing sea levels.
Towards real-time assessment of marine hazards: Testing the feasibility of seafloor displacement measurements for monitoring submarine landslides
Dr. Felix Gross,
By 2060 more than 1 Billion people could be living in low-elevation coastal zones (Neumann et al. 2015). Continental margins are increasingly used for wind parks, hydrocarbon extraction, pipelines, telecommunication cables, fishing, and mining. The increasing coastal population and new ventures in offshore human activities set new challenges to the assessment and mitigation of marine hazards. Submarine landslides, which have repeatedly caused devastating tsunamis and destroyed seabed infrastructure, are one of the most dangerous marine hazards. In contrast to earthquakes, where endangered areas are relatively well constrained and recurrence rates are often known from historic records, occurrence and timing of submarine landslides remain largely enigmatic (Talling et al. 2014). Therefore, hazard assessments for submarine landslides are more difficult than for other marine geohazards. Given the urgent need for improved hazard assessments, key future challenges are the identification of endangered areas, real-time monitoring of submarine slopes, and development of early warning systems. This project aims to take a step towards these challenges by (I) testing the feasibility of seafloor instruments for in-situ monitoring of landslide-related seafloor deformation, and (II) benchmarking how the data can be used to gain insight into active landslide processes. If successful, landslide monitoring will not only improve our understanding of submarine landslide processes but may well provide a basis for future hazard assessment, disaster mitigation, preparedness, and sustainable use of seafloor resources, making Kiel a pioneer in the field.
From hazard analysis to an integrated risk assessment- Can we do better?
Prof. Athanasios Vafeidis,
Dr. Felix Gross,
Ocean hazards are a great threat to coastal communities, offshore infrastructure, and natural habitats. In this proposal, we aim to conduct an integrative risk assessment for the geologically active, and hence vulnerable area, off East Sicily. We will test if our previous geophysical and geological work on geo-hazards, when combined with a comprehensive vulnerability study, leads to an improved risk assessment. Hence, the project covers the next steps after hazard identification and classification by incorporating different disciplines and methods such as geosciences, geography, computer sciences and statistics.
Mercury and dimethylmercury pollution in the ecosystem of the Kieler Förde as a result of historical use of air defence ammunition
Prof. Edmund Maser,
This project will study the distribution and fate of elemental mercury (Hg) and methylated Hg in the southwest Baltic Sea, and the biomagnification of these toxic substances in the aquatic food chain. These Hg compounds are anthropogenic pollutants and pose a threat to ecosystem and public health, and are thus of concern to regulatory authorities of Schleswig-Holstein. We will investigate strongly polluted and control sites, with a specific focus on a region off Kiel where >1.2 million mercurycontaining anti-aircraft grenades were shot from World War II artillery training grounds and now litter the seabed. The main aim of this study is to determine the distribution of Hg in the waters and sediments of the southwest Baltic Sea derived from munitions deployed >70 years, and how much has moved into the food chain. The project will provide direct policy relevant information to the Schleswig-Holstein government on compliance of this EU Water Framework Directive Priority Compound.
Sediment stabilization through biotechnically enhanced microbial mineral formation
Prof. Frank Wuttke,
Mechanical and hydraulic behavior of sub-sea sediments is poorly understood, and prediction of sediment destabilization and mechanical failure is linked to extreme uncertainties. This concerns deep-sea technical activities such as drilling, natural gas production or deployment of deep-sea equipment, stimulating intense effort towards developing novel strategies for sub-marine soil or slope stabilization. Inspired by recent success of microbial carbonate precipitation for terrestrial civil and environmental engineering objectives such as soil stabilization or building restoration1,2, it is assumed that biotechnical precipitation of carbonate minerals could also be the remedy for sub-sea sediment stability issues3. Although engineering objectives appear to be similar, technology transfer might be complicated due to vastly different physical, chemical and microbiological conditions in terrestrial and marine environments. Here we propose a combined microbiological-geomechanical approach to elucidate biotechnical potentials of microbial precipitation and mineral formation for sub-sea sediment stabilization. Our key objective is to test and quantify mechanical and hydraulic effects from different microbially precipitated amorphous phases and minerals (Ca.Mg-carbonates, metal sulfides, metal oxides/hydroxides) under in situ conditions in high-pressure flow-through incubation studies using novel and unique triaxial test systems4. This project brings together scientists from marine microbiology and soil mechanics, combining expertise from CAU and GEOMAR workgroups synergistically in collaborative lab experiments, data evaluation and numerical simulation.
