Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Modern low-oxygen marine systems exhibit patterns of molybdenum–uranium covariation
that can be linked to specific attributes and processes of the depositional system, including …

Methane transport from subsurface reservoirs to shallow marine sediment is characterized
by unique biogeochemical interactions significant for ocean chemistry. Sulfate-Methane …

We measured solid-phase Mo and U concentrations in marine sediments from the
California, Mexico, Peru, and Chile margins to ascertain the behavior of Mo and U during …

Coastal wetlands are an important source of methane emissions, and understanding the
mechanisms that control methane emissions from coastal wetlands is of great significance to …

Sterane biomarkers preserved in ancient sedimentary rocks hold promise for tracking the
diversification and ecological expansion of eukaryotes. The earliest proposed animal …

We present new Mo isotope data from the Mexican continental margin that, in conjunction
with previous data, allow us to propose a mechanistic description of the Mo isotope system …

We present molybdenum isotope and concentration data from 14 sites in the eastern Pacific
from the central California to the Peru margin. The environments studied have been chosen …

Sulfate and methane diffuse vertically along opposed concentration gradients into the
sulfate-methane transition in subsurface marine sediments where anaerobic oxidation of …

The sedimentary fluxes controlling potassium (K) budget of the oceans and the isotope
composition of K (δ 41 K) potentially yield valuable information about the global K cycling …
