The chemical composition of our oceans is not constant but has varied significantly over geological time. In a new study, researchers describe a novel method for reconstructing past ocean chemistry ...

There is no shortage of calcium carbonate. It is found in many rocks and mountains as limestone, chalk or marble. It is an essential component of construction materials such as cement and plaster, but ...

What links sea urchins, limestone and climate change? The common thread is calcium carbonate, one of the most widespread minerals on Earth. UC Davis researchers have now measured the energy changes ...

A chemical boundary in the deep sea may have helped shape abyssal ecosystem composition based on body type. The discovery has implications for how these communities could be affected by climate change ...

Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New ...

Earth's ocean absorbs carbon dioxide from the atmosphere, helping to temper the impact of climate change but increasing ocean ...

Experts at Newcastle University, UK, have discovered that in the presence of a Nickel catalyst, CO2 can be converted rapidly and cheaply into the harmless, solid mineral, calcium carbonate. The ...

For more than a quarter billion years, coral reefs did far more than brighten shallow seas. Long before humans appeared, ...
