Comparative Analysis of Methane-Oxidizing Archaea and Sulfate-Reducing Bacteria in Anoxic Marine Sediments
ABSTRACT The oxidation of methane in anoxic marine sediments is thought to be mediated by a consortium of methane-consuming archaea and sulfate-reducing bacteria. In this study, we compared resultsExpand

CARBON ISOTOPES IN BIOLOGICAL CARBONATES : RESPIRATION AND PHOTOSYNTHESIS
Respired carbon dioxide is an important constituent in the carbonates of most air breathing animals but is much less important in the carbonates of most aquatic animals. This difference isExpand

Late Paleocene to Eocene paleoceanography of the equatorial Pacific Ocean: Stable isotopes recorded at Ocean Drilling Program Site 865, Allison Guyot
An expanded and largely complete upper Paleocene to upper Eocene section was recovered from the pelagic cap overlying Allison Guyot, Mid-Pacific Mountains at Ocean Drilling Program (ODP) Site 865Expand

Global and local variations of interstitial sulfate gradients in deep-water, continental margin sediments: Sensitivity to underlying methane and gas hydrates
Abstract We test a hypothesis relating large pore water sulfate gradients to upward methane flux and the presence of underlying methane gas hydrate on continental rises by examining: (1) pore waterExpand

Biological Communities at the Florida Escarpment Resemble Hydrothermal Vent Taxa
Dense biological communities of large epifaunal taxa similar to those found along ridge crest vents at the East Pacific Rise were discovered in the abyssal Gulf of Mexico. These assemblages occur onExpand

Marine pore-water sulfate profiles indicate in situ methane flux from underlying gas hydrate
Marine pore-water sulfate profiles measured in piston cores are used to estimate methane flux toward the sea floor and to detect anomalous methane gradients within sediments overlying a major gasExpand

Direct measurement of in situ methane quantities in a large gas-hydrate reservoir
Certain gases can combine with water to form solids—gas hydrates—that are stable at high pressures and low temperatures1,2. Conditions appropriate for gas-hydrate formation exist in many marineExpand

Mid-Cretaceous strontium-isotope stratigraphy of deep-sea sections
Large variations exist between published mid-Cretaceous (late Barremian to early Turonian stages) seawater Sr-isotope stratigraphies; this has resulted in disparate interpretations of crustalExpand

Caught in the act: the 20 December 2001 gravity flow event in Monterey Canyon
A sediment gravity flow descended through the axis of Monterey Canyon on 20 December 2001 at 13:35 Pacific standard time. The timing of this event is documented by a current-meter package whichExpand

Authigenic carbonate formation at hydrocarbon seeps in continental margin sediments: A comparative study
Authigenic carbonates from five continental margin locations, the Eel River Basin, Monterey Bay, Santa Barbara Basin, the Sea of Okhotsk, and the North Sea, exhibit a wide range of mineralogical andExpand
