Many corals and sponges form skeletons that support and shape their bodies. Whereas biomineralization—the formation of these skeletons—has been intensively studied in corals, the main ecosystem ...

A high-density water-based drilling fluid (WBDF) is crucial for maintaining wellbore stability, controlling formation pressures, and optimizing drilling performance in challenging subsurface ...

Many marine organisms, including corals, build skeletons from calcium carbonate – in the form of calcite or aragonite. The current composition of seawater favors the formation of aragonite – but soft ...

The calcite grains forming the wall plates of the giant barnacle Austramegabalanus psittacus have a distinctive surface roughness made of variously sized crystalline nanoprotrusions covered by ...

For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes ...

ALBUQUERQUE, N.M. — A calcite formation named Snowy River could prove a gold mine for scientists. Snowy River, believed to be the largest continuous calcite formation in the world, was discovered in ...
