DOI: 10.1002/lom3.10307
Abstract: We present a marine two-phase gas model in one dimension (M2PG1) resolving interaction between the free and dissolved gas phases and the gas propagation toward the atmosphere in aquatic environments. The motivation for the model… read more here.

DOI: 10.1016/j.jseaes.2018.11.011
Abstract: Abstract Cold seeps frequently occur at the seafloor along continental margins. The dominant biogeochemical processes at cold seeps are the combined anaerobic oxidation of methane and sulfate reduction, which can significantly impact the global carbon… read more here.

Widespread methane seepage along the continental margin off Svalbard - from Bjørnøya to Kongsfjorden
Sign Up to like & getrecommendations! Published in 2017 at "Scientific Reports"
DOI: 10.1038/srep42997
Abstract: Numerous articles have recently reported on gas seepage offshore Svalbard, because the gas emission from these Arctic sediments was thought to result from gas hydrate dissociation, possibly triggered by anthropogenic ocean warming. We report on… read more here.

DOI: 10.1130/g38967.1
Abstract: During the Phanerozoic, Earth has experienced a number of transient global warming events associated with major carbon cycle perturbations. Paradoxically, many of these extreme greenhouse episodes are preceded or followed by cold climate, perhaps even… read more here.

DOI: 10.3389/fmars.2019.00765
Abstract: Benthic foraminifera have been widely used as proxy for paleo-methane emissions, mainly based on their stable isotopic signature. In cold seeps, the ecology of these organisms remains uncertain, in particular their ability to thrive during… read more here.
