2024年9月13日 · What is the carbon cycle? Carbon makes up the backbone of all life on Earth. It’s found in the cells of all living things, is abundant in rocks and sediments, and is also found in the atmosphere and ocean. But carbon doesn’t remain in one place. Individual atoms move from one reservoir to another: between the atmosphere and the oceans, from plants to animals to …

2015年11月23日 · Carbon is a building block for all life and plays a key role in regulating Earth’s climate. It shuttles throughout the planet in two major cycles. The first is the biospheric carbon cycle. Plants convert carbon dioxide from the air into …

Carbon is constantly on the move, changing form and location and making life on Earth possible. The carbon cycle traces the path of carbon through the ocean, atmosphere, land, and deep Earth.

2015年5月13日 · The new study gives scientists a firmer handle on measuring the important, and heretofore elusive, role of global rivers in the planetary carbon cycle and enhances their ability to predict how riverine carbon export may shift as Earth’s climate changes.

1997年12月1日 · This complex carbon-transporting ocean process, often called the “biological pump,” is a critical mechanism in preventing what we now know as the “greenhouse effect,” the collection of gases in the atmosphere that hinders upward transport of heat. Understanding of Earth’s carbon cycle is one of humankind’s great scientific questions.

2020年9月10日 · The biological carbon pump removes atmospheric carbon by transporting carbon-rich material from surface waters to the deep ocean, aiding climate regulation.

2020年4月6日 · A new study shows that the efficiency of the ocean’s “biological carbon pump” has been drastically underestimated with implications for future climate assessments.

2020年1月9日 · When CO₂ enters the ocean, where does this heat-trapping gas go? WHOI investigates how much carbon from the surface ocean is dispatched to the twilight zone.

2019年12月11日 · Blue carbon refers to atmospheric carbon captured and stored by the ocean, which mitigates the effects of climate change by storing carbon for long periods of time.
