Authigenic carbonates from the eastern Black Sea as an archive for shallow gas hydrate dynamics – results from the combination of CT imaging with mineralogical and stable isotope analyses.

Bahr, André; Pape, Thomas; Abegg, Friedrich; Bohrmann, Gerhard; van Weering, Tjeerd C E; Ivanov, M K (PANGAEA, 2010-11-22)

Authigenic carbonates associated with cold seeps provide valuable archives of changes in the long-term seepage activity. To investigate the role of shallow-buried hydrates on the seepage strength and fluid composition we ...
Factors influencing 14C concentrations of algal and archaeal lipids and their associated sea surface temperature proxies in the Black Sea.

Kusch, Stephanie; Rethemeyer, Janet; Hopmans, Ellen C; Wacker, Lukas; Mollenhauer, Gesine (PANGAEA, 2016-07-25)
Geological control and magnitude of methane ebullition from a high-flux seep area in the Black Sea - the Kerch seep area.

Römer, Miriam; Sahling, Heiko; Pape, Thomas; Bahr, André; Feseker, Tomas; Wintersteller, Paul; Bohrmann, Gerhard (PANGAEA, 2012-07-23)
High-intensity gas seepage causes rafting of shallow gas hydrates in the southeastern Black Sea.

Pape, Thomas; Bahr, André; Klapp, Stephan A; Abegg, Friedrich; Bohrmann, Gerhard (PANGAEA, 2011-08-15)

Submarine gas hydrates are a major global reservoir of the potent greenhouse gas methane. Since current assessments of worldwide hydrate-bound carbon vary by one order of magnitude, new technical efforts are required for ...
Molecular and isotopic partitioning of low-molecular-weight hydrocarbons during migration and gas hydrate precipitation in deposits of a high-flux seepage site.

Pape, Thomas; Bahr, André; Rethemeyer, Janet; Kessler, John D; Sahling, Heiko; Hinrichs, Kai-Uwe; Klapp, Stephan A; Reeburgh, William S; Bohrmann, Gerhard (PANGAEA, 2010-07-15)

Detailed knowledge of the extent of post-genetic modifications affecting shallow submarine hydrocarbons fueled from the deep subsurface is fundamental for evaluating source and reservoir properties. We investigated gases ...
Vodyanitskii mud volcano, Sorokin Trough, Black Sea: Geological characterization and quantification of gas bubble streams.

Sahling, Heiko; Bohrmann, Gerhard; Artemov, Yuriy G; Bahr, André; Brüning, Markus; Klapp, Stephan A; Klaucke, Ingo; Kozlova, Elena; Nikolovska, Aneta; Pape, Thomas; Reitz, Anja; Wallmann, Klaus (PANGAEA, 2010-05-04)

Vodyanitskii mud volcano is located at a depth of about 2070 m in the Sorokin Trough, Black sea. It is a 500-m wide and 20-m high cone surrounded by a depression, which is typical of many mud volcanoes in the Black Sea. ...
