Evidence from fossil shells suggests that falling seawater calcium helped lock away carbon dioxide and helped cool Earth after the dinosaurs.

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

A recent study found that ocean acidification is dissolving the shells of Dungeness crabs across the US Pacific Northwest. The study, published in Science of The Total Environment, analyzed Dungeness ...

Q. At what level of hydrogen ion concentration in the ocean will the coral reefs and other calcifiers begin to show signs of dissolution? – Submitted by Mackenzie B., 12, Key West, Fl. The hydrogen ...

A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's ...

Sea cucumbers secrete acidic compounds that may be weakening the structure of the coral communities in which they live. The main component of a coral reef is calcium carbonate (CaCO3), a mineral that ...

A University of Nebraska–Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery that paints a clearer picture of carbon flow through the environment and ...
