Usually, Buhler spends his time modeling the carbon-dioxide cycle on Mars today. During Martian winter, a layer of carbon-dioxide ice settles out on top of the polar caps of water ice. While it is ...

In Buhler's model, a 0.4-mile-thick layer of carbon dioxide deposits on top of a 2.5-mile-thick layer of water ice, a layer of water ice about as thick as that which exists on the south pole today.

The model shows that in this ancient setting, warming the equatorial regions causes carbon dioxide to condense into a sheet 0.4 mile (0.6 km) thick at the poles, on top of a water-ice cap 2.5 ...

Ancient carbon cycle on past Mars Observations of Mars from orbiting satellites and rovers show river channels and dry lakes that suggest the Martian surface once had liquid water.

A research team has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO₂) in supercritical water. These findings are crucial for understanding the ...

Diatom surprise could rewrite the global carbon cycle Date: July 17, 2024 Source: University of California - San Diego Summary: When it comes to diatoms that live in the ocean, new research ...

Carbon dioxide dissolved in water—including saltwater—produces carbonic acid. High levels of atmospheric carbon dioxide create acid rain and depress the pH of surface water, including the ocean.
