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 ...

Deep-water cold seeps, sedimentary environments and ecosystems of the Black and Tyrrhenian Seas and Gulf of Cadiz.

Kenyon, Neil H; Bohrmann, Gerhard (PANGAEA, 2008-10-30)

Diagenetic transformation of dissolved organic nitrogen compounds under contrasting sedimentary redox conditions in the Black Sea.

Extending the analytical window for water-soluble organic matter in sediments by aqueous Soxhlet extraction.

Schmidt, Frauke; Koch, Boris P; Witt, Matthias; Hinrichs, Kai-Uwe (PANGAEA, 2014-11-25)

Gas chromatographic analysis of methanol and ethanol in marine sediment pore waters: Validation and implementation of three pretreatment techniques.

Zhuang, Guang-Chao; Lin, Yu-Shih; Elvert, Marcus; Heuer, Verena B; Hinrichs, Kai-Uwe (PANGAEA, 2014-05-12)

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)

Gridded bathymetry from multibeam echosounder EM122 data of the cruise M84/2, off Samsun (2011).

Wintersteller, Paul; dos Santos Ferreira, Christian; Schmager, Marten (PANGAEA, 2018-08-24)

Multibeam echosounder (MBES) data recorded during RV METEOR cruise M84-2 between 26.02.2011 and 02.04.2011 in the Black Sea. The aim of the cruise was to investigate the gas hydrate distribution in sediments of the Black ...

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 ...

Hydrocarbon gases in deposits from mud volcanoes in the Sorokin Trough, northeatsern Black Sea.

Blinova, Valentina N; Ivanov, Michael; Bohrmann, Gerhard (PANGAEA, 2003-09-15)

Hydrocarbon gases were determined in sediments from three mud volcanoes in the Sorokin Trough. In comparison to a reference station outside the mud volcano area, the deposits are characterized by an enrichment of high-molecular ...

Intact polar lipids in marine sediments: improving analytical protocols and assessing planktonic and benthic sources.

Schröder, Jan Martin (PANGAEA, 2015-12-09)

This PhD thesis focused on the analysis and application of microbial membrane lipids as biomarkers in marine sediments. Existing protocols for lipid extraction from marine sediments and biomass were modified. In addition, ...

Isoprenoid quinones resolve the stratification of redox processes in a biogeochemical continuum from the photic zone to deep anoxic sediments of the Black Sea.

Becker, Kevin W; Elling, Felix J; Schröder, Jan Martin; Lipp, Julius S; Goldhammer, Tobias; Zabel, Matthias; Elvert, Marcus; Overmann, Jörg; Hinrichs, Kai-Uwe (PANGAEA, 2018-10-16)

Late Glacial to Holocene paleoenvironmental evolution of the Black Sea.

Bahr, André (PANGAEA, 2005-01-07)

Methane at the sediment–water transition in Black Sea sediments.

Riedinger, Natascha; Brunner, B; Lin, Yu-Shih; Vossmeyer, Antje; Ferdelman, Timothy G; Jørgensen, Bo Barker (PANGAEA, 2010-02-20)

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 ...
