Methane oxidation following submarine permafrost degradation: Measurements from a central Laptev Sea shelf borehole.

Overduin, Pier Paul; Liebner, Susanne; Knoblauch, Christian; Günther, Frank; Wetterich, Sebastian; Schirrmeister, Lutz; Hubberten, Hans-Wolfgang; Grigoriev, Mikhail N (PANGAEA, 2015-05-18)
Methane turnover and methanotrophic communities in arctic aquatic ecosystems of the Lena Delta, Northeast Siberia.

Osudar, Roman; Liebner, Susanne; Alawi, Mashal; Yang, Sizhong; Bussmann, Ingeborg; Wagner, Dirk (PANGAEA, 2016-06-20)

Large amounts of organic carbon are stored in Arctic permafrost environments, and microbial activity can potentially mineralize this carbon into methane, a potent greenhouse gas. In this study, we assessed the methane ...
Microbial community composition and abundance after millennia of submarine permafrost warming.

Mitzscherling, Julia; Horn, Fabian; Winterfeld, Maria; Mahler, Linda; Kallmeyer, Jens; Overduin, Pier Paul; Winkel, Matthias; Grigoriev, Mikhail N; Wagner, Dirk; Liebner, Susanne (PANGAEA, 2018-10-15)

The mobilization of carbon in degrading permafrost is a long-term process and an important feedback upon climate change. Under submarine conditions substantial permafrost warming occurs millennia before permafrost thaws, ...
Russian-German cooperation SYSTEM LAPTEV SEA : the Expeditions Laptev Sea - Mamontov Klyk 2011 & Buor Khaya 2012.

Overduin, Pier Paul; Liebner, Susanne; Knoblauch, Christian; Günther, Frank; Wetterich, Sebastian; Schirrmeister, Lutz; Hubberten, Hans-Wolfgang; Grigoriev, Mikhail N (PANGAEA, 2015-05-18)

Submarine permafrost degradation has been invoked as a cause for recent observations of methane emissions from the seabed to the water column and atmosphere of the East Siberian shelf. Sediment drilled 52 m down from the ...
The development of permafrost bacterial communities under submarine conditions.

Mitzscherling, Julia; Winkel, Matthias; Winterfeld, Maria; Horn, Fabian; Yang, Sizhong; Grigoriev, Mikhail N; Wagner, Dirk; Overduin, Pier Paul; Liebner, Susanne (PANGAEA, 2017-03-22)

Submarine permafrost is more vulnerable to thawing than permafrost on land. Besides increased heat transfer from the ocean water, the penetration of salt lowers the freezing temperature and accelerates permafrost degradation. ...
