By doing so, his model encapsulates the full carbon dioxide cycle from the regolith, to atmosphere, to frozen polar caps. For this study, he applied the model to a pivotal era in Mars' history.

Chemically, carbon dioxide is incredibly simple – it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's ...

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.

Dec. 8, 2023 — Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ...

Scripps Institution of Oceanography announced Thursday that the amount of the greenhouse gas carbon dioxide in the atmosphere continues its steady increase, setting a new record in May. The NOAA ...

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 ...

Ancient Mars may have had a carbon cycle − a new study suggests the red planet may have once been warmer, wetter and more favorable for life Published: May 6, 2025 8:34am EDT Elisabeth M ...

Chemically, carbon dioxide is incredibly simple—it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's ...

The paper, led by Planetary Science Institute Research Scientist Peter Buhler, describes how 3.6 billion years ago, carbon dioxide froze out of Mars' atmosphere and deposited on top of a water ice ...
