Not exact matches

When carbon dioxide, CO2, from the atmosphere is absorbed by the ocean, it forms carbonic acid (the same thing that makes soda fizz), making the ocean more acidic and decreasing the ocean's pH. This increase in acidity makes it more difficult for many marine organisms to grow their shells and skeletons, and threatens coral reefs the world over.

He recently helped form an effort between the Aquarium of the Pacific and City of Hope to begin a search for cancer cures in the potent chemicals produced by marine organisms.

Physically formed by brown macroalgae, kelp forests provide a unique, three - dimensional habitat for marine organisms [4] and are a source for understanding many ecological processes.

The material that makes up pteropod shells is aragonite, a common mineral form of calcium carbonate, which is also secreted by other marine organisms to form external skeletal material.

Present - day ocean surface waters are supersaturated for the major carbonate mineral forms used by marine organisms, including the more soluble form aragonite (corals, many mollusks) and the less soluble form calcite (coccolithophores, foraminifera, and some mollusks).

Carbon is transported within the ocean by three mechanisms; (1) the «solubility pump» (see glossary), (2) the «biological pump» (see case study), (3) the «marine carbonate pump» which is caused by marine organisms forming shells in the surface ocean.

When carbon dioxide from the atmosphere is absorbed by the ocean, it forms carbonic acid, H2CO3, which makes the ocean more acidic and decreases its pH. This makes it more difficult for many marine organisms to grow their shells and skeletons, and threatens coral around the globe.

Aragonite - A calcium carbonate (limestone) mineral, used by shell - or skeleton - forming, calcifying organisms such as corals (warm - and coldwater corals), some macroalgae, pteropods (marine snails) and non-pteropod molluscs such as bivalves (e.g., clams, oysters), cephalopods (e.g., squids, octopuses).

When carbon dioxide, CO2, from the atmosphere is absorbed by the ocean, it forms carbonic acid — the same stuff that makes soda fizz — making the ocean more acidic and thus more difficult for many marine organisms to grow their shells and skeletons and threatening coral reefs globally.
