Abrupt changes of temperature and water chemistry in the late Pleistocene and early Holocene Black Sea.

Bahr, André (PANGAEA, 2007-11-02)
Authigenic carbonate precipitates from the NE Black Sea: a mineralogical, geochemical, and lipid biomarker study.

Bahr, André; Pape, Thomas; Bohrmann, Gerhard; Mazzini, Adriano; Haeckel, Matthias; Reitz, Anja; Ivanov, M (PANGAEA, 2009-07-21)
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 ...
Complex plumbing systems in the near subsurface: geometries of authigenic carbonates from Dolgovskoy Mound (Black Sea) constrained by analogue experiments.

Mazzini, Adriano; Ivanov, Michael K; Nermoen, Anders; Bahr, André; Bohrmann, Gerhard; Svensen, Henrik; Planke, Sverre (PANGAEA, 2008-11-09)

Targeted sampling on the Dolgovskoy Mound (northern Shatsky Ridge) revealed the presence of spectacular laterally extensive and differently shaped authigenic carbonates. The sampling stations were selected based on sidescan ...
Diagenetic barium cycling in Black Sea sediments - A case study for anoxic marine environments.

Henkel, Susann; Mogollón, José M; Nöthen, Kerstin; Franke, Christine; Bogus, Kara; Robin, Eric; Bahr, André; Blumenberg, Martin; Pape, Thomas; Seifert, Richard; März, Christian; de Lange, Gert Jan; Kasten, Sabine (PANGAEA, 2012-04-24)
Estimated reservoir ages of the Black Sea since the Last Glacial.

Kwiecien, Ola; Arz, Helge W; Lamy, Frank; Wulf, Sabine; Bahr, André; Röhl, Ursula; Haug, Gerald H (PANGAEA, 2008-07-11)
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 ...
Late Glacial to Holocene paleoenvironmental evolution of the Black Sea.

Bahr, André (PANGAEA, 2005-01-07)
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 ...
Multicentennial-scale hydrological changes in the Black Sea and northern Red Sea during the Holocene and the Arctic/North Atlantic Oscillation.

Lamy, Frank; Arz, Helge W; Bond, Gerard C; Bahr, André; Pätzold, Jürgen (PANGAEA, 2006-05-03)
Profile of sediment echo sounding during METEOR cruise M84/2 with links to Parasound data files.

Römer, Miriam; Sahling, Heiko; Pape, Thomas; Bahr, André; Feseker, Tomas; Wintersteller, Paul; Bohrmann, Gerhard (PANGAEA, 2012-07-26)

We investigated gas bubble emissions at the Don-Kuban paleo-fan in the northeastern Black Sea regarding their geological setting, quantities as well as spatial and temporal variabilities during three ship expeditions between ...
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. ...
