Hydrocarbon concentrations from pressurized cores in the northern Gulf of Mexico

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...

Hydrate abundances at the high-flux Batumi seep area in the southeastern Blac...

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...

Sorption of volatile hydrocarbon gases (VHCs) to marine sediments is a recognized phenomenon that has been investigated in the context of petroleum exploration. However, little...

Temperature measurements, gas chemistry, and gas hydrates of the Dvurechenski...

The sediment temperature distribution at mud volcanoes provides insights into their activity and into the occurrence of gas hydrates. If ambient pressure and temperature...

Gas analysis of sediment cores from the Batumi seep area

Detailed knowledge of the extent of post-genetic modifications affecting shallow submarine hydrocarbons fueled from the deep subsurface is fundamental for evaluating source and...

Gas hydrate investigation at the Amsterdam mud volcano

We investigated gas hydrate in situ inventories as well as the composition and principal transport mechanisms of fluids expelled at the Amsterdam mud volcano (AMV; 2,025 m water...

(Table 4) In situ methane concentrations (Cm), amount of dissolved methane an...

C = Core length, C AOM = core length below AOM zone, GH = gas hydrate, vol = volume, ps = pore space and cv = core volume. * This gas:water ratio of 132/1 is in between the...

(Table 3) Molalities of C1-iC5 in pore water below the AOM zone

No pore water data are available for MAC-12. In 3 out of 4 MAC cores the lower limit of the AOM zone is less than 10 cm deep; the lower limit in MAC-12 is set at 10 cm. In...
