Fluids migration and sedimentary processes in Lake Baikal

Lake Baikal is the largest fresh water basin on Earth and represent a natural laboratory to investigate submarine volcanism, gas hydrate deposits, hydrocarbon fluids seepage sites, submarine slumps and slides, deep water canyons transport, tectonism and fluids migration. Since 2014 the Class@Baikal project trains new generation of scientists and discovers the secrets of Lake Baikal exploring it with bottom sampling and acoustics techniques.

Learning outcomes
The student will be an active player in all the phases of data collection analyses and interpretation. The candidate will join to a two weeks marine expedition in Lake Baikal actively participating to all the phases of cruise planning and data collection.

The student will receive an intense multidisciplinary training on marine investigating techniques (acoustic data interpretation, sea floor observations, bottom sampling) collecting the data used for her/his thesis. Laboratory/digital data processing, interpretation and integration of analysed data on broader context will follow.

This multicultural and multidisciplinary “Training Trough Research Program” offers possibilities for cooperation between different institutes and experts in marine geosciences.

Highlight topics:
The Class@Baikal expedition offers multiple topics for Master theses with multidisciplinary applications blending sedimentology, structural geology, geophysics, geochemistry and biology.

Geochemistry of the seeping fluids (oil, gas, water) can be used to investigate the reactions and the mechanisms controlling active volcanism and tectonic migration pathways. Numerous are the mud volcanoes at active seepage sites scattered over the lake. Every year new structures are discovered. .

The exploration of deep-water canyons and depositional systems using acoustic and bottom sampling data archives the lake geological history. At Baikal is present one of the largest and most complex deep-water canyon systems on Earth, - and it is largely unexplored.

Large scale sedimentary processes at submarine slides can be triggered by gas hydrates dissociation and seismic activity. Investigations will be done at one of the largest slides of the Lake.

Important information: 

  • The student must have a passport valid for at least 6 months beyond the departure date in order to apply for invitation and visa (minimum duration of 2 weeks), allowing for a round trip to Russia. It is the student's responsibility to make sure that this is case, three months in advance of the departure.
