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 …

Populations and metropolitan centers are accumulated in coastal areas around the world. In
view of the fact that they are geographically adjacent to coasts and intense anthropogenic …

The ocean contains unique biodiversity, provides valuable food resources and is a major
sink for anthropogenic carbon. Marine protected areas (MPAs) are an effective tool for …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

The balance between degradation and preservation of sedimentary organic carbon (OC) is
important for global carbon and oxygen cycles. The relative importance of different …

Inorganic geochemistry is a powerful tool in paleolimnology. It has become one of the most
commonly used techniques to analyze lake sediments, particularly due to the development …

Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout
the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon …

Soils represent the largest carbon reservoir within terrestrial ecosystems. The mechanisms
controlling the amount of carbon stored and its feedback to the climate system, however …

Coastal seagrass, mangrove and salt-marsh ecosystems—also termed blue-carbon
ecosystems—play an important role in the global carbon cycle. Much of the organic carbon …

Submarine turbidity currents form the largest sediment accumulations on Earth, raising the
question of their role in global carbon cycles. It was previously inferred that terrestrial …
