Methane discharge into the Black Sea and the global ocean via fluid flow through submarine mud volcanoes

Autor: Giovanni Aloisi, Gerhard Bohrmann, Manuela Drews, Klaus Wallmann

Publikováno v: Earth and Planetary Science Letters. 248:545-560

During the MARGASCH cruise M52/1 in 2001 with RV Meteor we sampled surface sediments from three stations in the crater of the Dvurechenskii mud volcano (DMV, located in the Sorokin Trough of the Black Sea) and one reference station situated 15 km to

Fluid expulsion from the Dvurechenskii mud volcano (Black Sea)

Autor: Manuela Drews, Giovanni Aloisi, Gerhard Bohrmann, Klaus Wallmann

Publikováno v: Earth and Planetary Science Letters. 225:347-363

Significant sediment–ocean chemical fluxes are produced by the expulsion of sedimentary fluids at continental margins. Although such fluxes could play a role in global geochemical cycles, few quantitative estimates of their global, or even regional

Mud volcanoes and gas hydrates in the Black Sea: new data from Dvurechenskii and Odessa mud volcanoes

Publikováno v: Geo-Marine Letters. 23:239-249

Meteor cruise M52/1 documented the presence of gas hydrates in sediments from mud volcanoes in the Sorokin Trough of the Black Sea. In a mud flow on the Odessa mud volcano, a carbonate crust currently forms in association with anaerobic methane oxida

Publikováno v: Marine Ecology Progress Series, 211 . pp. 27-42.
Scopus-Elsevier

Filamentous sulfur-oxidizing bacteria and geochemical parameters of sediments at the Makran accretionary wedge in the northeastern Arabian Sea off Pakistan were studied. The upper continental slope between 350 and 850 m water depth, which is in the c

Gas and fluid venting at the Makran accretionary wedge off Pakistan

Publikováno v: Geo-Marine Letters. 20:10-19

The Makran accretionary complex shows a distinct bottom-simulating reflector, indicating a thick gas-hydrate-bearing horizon between the deformational front and about 1350 m water depth which seals off the upward flow of gas-charged fluids. A field o

Publikováno v: Marine Chemistry

Two newly developed coring devices, the Multi-Autoclave-Corer and the Dynamic Autoclave Piston Corer were deployed in shallow gas hydrate-bearing sediments in the northern Gulf of Mexico during research cruise SO174 (Oct–Nov 2003). For the first ti

Efficiency of the benthic filter: Biological control of the emission of dissolved methane from sediments containing shallow gas hydrates at Hydrate Ridge

Autor: S. Gubsch, Manuela Drews, M. Poser, Roger Luff, Olaf Pfannkuche, Peter Linke, Stefan Sommer, Jens Greinert, T. Viergutz, Martin Pieper

Publikováno v: Global Biogeochemical Cycles. 20

[1] In marine sedimentary environments, microbial methanotrophy represents an important sink for methane before it leaves the seafloor and enters the water column. Using benthic observatories in conjunction with numerical modeling of pore water gradi

Evidence for the submarine weathering of silicate minerals in Black Sea sediments: Possible implications for the marine Li and B cycles

Autor: Manuela Drews, Klaus Wallmann, Giovanni Aloisi, Gerhard Bohrmann

Publikováno v: Geochemistry, Geophysics, Geosystems. 5

[1] The role of sediment diagenesis in the marine cycles of Li and B is poorly understood. Because Li and B are easily mobilized during burial and are consumed in authigenic clay mineral formation, their abundance in marine pore waters varies conside
