Marine Geophysics and Hydroacoustics


The projects of the group are located in various parts of the world, both in the middle of the oceans and near coastlines close to Kiel. Also remote lakes, only reached by helicopter, are investigated.


Baltic Sea environmental assessments by innovative opto-acoustic remote sensing, mapping, and monitoring

The EU program BONUS will fund our project ECOMAP (start 1st of October 2017). The goal of ECOMAP is to develop innovative methods for improved remote sensing of the seafloor in the Baltic Sea, especially addressing the physical impact of benthic life on the sensing procedures. We propose new measurement techniques and a catalogue detailing new procedures on how to implement remote sensing methods for selected habitats. More...

Ocean Hazard Risk Assessment

Studies on ocean hazard analysis and their magnitude/frequency relationship have been primarily championed by natural scientists. The physical and geological complexity of these hazards proposed by natural scientists is often not considered or adapted by social scientists during their risk and vulnerability assessments. Therefore, the field of natural hazard and risk assessment is one of the most prominent fields of research, once it comes to convergent or transdisciplinary sciences.

Submarine natural hazards like earthquakes, landslides and related tsunamis pose a great threat to coastal communities. More...

Geohazards off Southern Italy

The continental margins of southern Italy are located along converging plate boundaries, which are affected by intense seismicity and volcanic activity. Most of the coastal areas experienced severe earthquakes, landslides, and tsunamis in historical and/or modern times. The most prominent example is the Messina earthquake of Dec. 28, 1908 (Ms=7.3; 80,000 casualties), which was characterized by the worst tsunami Italy experienced in the historical time (~2000 casualties).

NW Africa

The passive margin off NW-Africa is investigated by the workgroup since a long time; it is shaped by a complex interplay of sediment transport processes, directed both downslope and alongslope. During several cruises, sediment transport processes between 12° and 29°N off Senegal, Mauritania, and Western Sahara were investigated by means of geophysical and sedimentological methods. More...

Lake Ohrid

Person to contact: Katja Lindhorst und Sebastian Kastel

Lake Ohrid, located on the Balkan Peninsula within the Dinaride-Hellenide-Albanide mountain chain (Macedonia/Albania) is probably the oldest, continuously existing lake in Europe (2-5 Ma). More

Tuaheni Landslides

SCHLIP3D - Submarine Clathrate Hydrate Landslide Imaging Project (Tuaheni Slides off the east coast of New Zealand)

The dynamics of submarine landslides is only poorly understood. While some landslides rapidly disintegrate others may stay as coherent blocks. Recently, it has been proposed that submarine landslides could also be characterized by very slow (creeping) deformation. The Tuaheni landslide complex off the east coast of New Zealand may acts as key site for investigating such slow-slipping landslides. We collected a 3D-seismic dataset covering parts of the slide complex by means of the so-called P-cable system during research cruise TAN1404 (13.04. – 08.05.2014) of the Kiwi Research Vessel RV Tanagaro.

Caldera Lake Bolsena (Italy)

Person to contact: Katja Lindhorst

The Bolsena caldera formed between 0.6 and 0.2 Ma is an ideal site to study the tectonic and volcanic evolution of calderas. The main area is covered by an 150 m deep lake. A High resolution hydro-acoustic survey using a multichannel reflection seismic system and a sediment echo-sounder system were conducted in Sept. 2012.

As space was limited we used a rowing boat towed by a rubber boat to handle a 36 m long and 24 channel streamer to receive seismic reflections produced using a Mini GI-Gun (0.25 l). More
