The new data on strontium in deep-sea sediments indicate that though foraminifera and coccoliths may be low in strontium (1,200–1,800 p.p.m.) yet the deep-sea carbonate deposits are higher as a ...

Objects and Ideograms has developed a method to 3D-print calcium carbonate, which can be used as a scaffold for the growth of coral polyps and other aquatic life. Coral carbonate utilises its ...

Beneath the soft bodies of scleractinian, or stony corals, polyps secrete a calcium carbonate skeleton, and it is this skeleton that becomes the foundation of coral reef ecosystems. Coral colonies ...

The new research, which was published in Limnology and Oceanography Letters, paints a worrying picture for the Great Barrier ...

Coral reefs are made up of colonies of hundreds to thousands of tiny individual corals, called polyps. These marine invertebrate animals have hard exoskeletons made of calcium carbonate, and are ...

Coral bleaching occurs when corals lose their algae, exposing their white calcium carbonate skeletons. Corals helped Darwin refine his ideas about evolution. His first scientific book after ...

Coral reefs consist of hundreds of thousands of coral polyps - marine animal invertebrates with hard calcium carbonate exoskeletons. Different species grow to form a variety of measurements and ...

Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean, the faster the shells dissolve. By ...
