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 ...

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 ...

The carbonate compensation depth — a zone where high pressure and low temperature creates conditions so acidic it dissolves shell and skeleton — could make up half of the global ocean by the end of ...

Liz is a marine biologist, environmental regulation specialist, and science writer. She has previously studied Antarctic fish, seaweed, and marine coastal ecology. Ocean acidification, or OA, is the ...

In the deepest parts of the ocean, below 4,000 metres, the combination of high pressure and low temperature creates conditions that dissolve calcium carbonate, the material marine animals use to make ...

When raised in warm water and exposed to acidified water, bryozoans, honeycomb-shaped sea creatures, dissolved within two months, researchers observed. (Eric Sanford/UC Davis) Warming waters plus ...

The slow part of a chemical reaction that allows carbon to be sequestered in the ocean has now been identified by researchers, who have demonstrated how to speed it up with a common enzyme. Scientists ...

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 ...
