New thoughts on how carbonates record global carbon cycle
When scientists want to study Earth's very ancient geological past—typically greater than 100 million years ago—they often turn to rocks called carbonates.

Investigation of oceanic 'black carbon' uncovers mystery in global carbon cycle
In understanding the global carbon cycle, "black carbon"—decay-resistant carbon molecules altered by exposure to fire or combustion—has long been presumed to originate on land and work its way to the ocean via rivers ...

Largest mapping of breathing ocean floor key to understanding global carbon cycle
Marine sediments play a crucial role in the global carbon cycle due to the oxygen consumption and CO2 respiration of the organisms that live in and on the ocean floor. To help predict the changing contribution of this respiration ...

The shelf life of pyrite
The last 2.6 million years are characterized by glacial cycles, a regular alternation of cold and warm periods. It is widely accepted that changes in the concentrations of carbon dioxide and other greenhouse gases in the ...

Northern peatlands may contain twice as much carbon as previously thought
Northern peatlands may hold twice as much carbon as scientists previously suspected, according to a study published today in Nature Geoscience. The findings suggest that these boggy areas play a more important role in climate ...

More than just whale food: Krill's influence on carbon dioxide and global climate
Antarctic krill are well-known for their role at the base of the Southern Ocean food web, where they're food for marine predators such as seals, penguins and whales.

Clay minerals call the shots with carbon
Clay minerals suspended in seawater binds sedimentary organic carbon to their mineral surfaces. But the quantity of carbon that is bound and the source of that carbon very much depends on the clay mineral in question. A research ...

Grim projections for the ocean—and the life within it
The chain of causation that connects rising concentrations of greenhouse gases in the atmosphere to the marine biota has been made clearer by the Intergovernmental Panel on Climate Change (IPCC) report "Special Report on ...

Microbes in warm soils released more carbon than those in cooler soils
As one descends a mountain, the temperature steadily increases. A new study by a team including Andrew Nottingham, a research associate at the Smithsonian Tropical Research Institute (STRI) and post-doctoral fellow at the ...
