Bacteria release more carbon from the ocean than previously thought（图）
Bacteria release carbon ocean previously thought
2021/4/23
A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings ...
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the oceans. Now researchers from the University of Connecticut and other institu...

The sea is Earth's most formidable carbon dioxide storage machine, but mysteries abound about the interlocking processes and the myriad organisms involved.Now, thanks to NSF-funded research published ...
Salt marshes' capacity to store carbon may be threatened by nitrogen pollution（图）
Salt marshes capacity carbon nitrogen pollution
2019/10/18
Deep in the waterlogged peat of salt marshes, carbon is stored at much greater rates than in land ecosystems, serving as an offset to climate change caused by carbon dioxide (CO2) build-up in the atmo...
Tiny Shells Indicate Big Changes to Global Carbon Cycle
Tiny Shells Indicate Big Changes Global Carbon Cycle

Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis. For the stud...
UM Researchers Study Vast Carbon Residue of Ocean Life
UM Researchers Vast Carbon Residue Ocean Life
2016/11/4
The oceans hold a vast reservoir—700 billion tons—of carbon, dissolved in seawater as organic matter, often surviving for thousands of years after being produced by ocean life. Yet, little is known ab...

Autonomous Observations Ocean Biological Carbon Pump
2015/7/3
Prediction of the substantial biologically mediated carbon flows in a rapidly changing and acidifying ocean requires model simulations informed by observations of key carbon cycle processes on the app...
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the rem...
