Are methane hydrates dissolving?
Date:8/13/2012

e gas outlets in up to 400 metres depth. "It is interesting for us, for example, to find out whether special microorganisms that can break down the methane before it is released in the atmosphere have settled around the outlets" explains Professor Tina Treude from GEOMAR, who will be running the microbiological work during the expedition.

Parallel to this, geophysicists, lead by Professor Sebastian Krastel from GEOMAR, will investigate the slopes under the gas outlet spots for signs of instability using acoustic and seismic methods. "The methane hydrates act like binding cement on these slopes. If they dissolve, chances are that parts of the slopes will slide", explains Professor Krastel, who focuses on marine hazards at GEOMAR.

"Overall the program on this trip is very extensive. Now let us hope that the weather will play along so that we can conduct all planned tests", says the head of the expedition Christian Berndt shortly before the departure to Iceland.
