pH level

A common pH definition is: " a logarithmic scale, from 1 to 14, used to describe the acidity or alkalinity of a solution ". Blood in the human body should be close to 7.4 on the pH scale. A pH level of less than 7 indicates an acidic solution while a pH greater than 7 indicates an alkaline solution

Atoil

An atoll is a ring-shaped coral reef, island, or series of islets. An atoll surrounds a body of water called a lagoon. Sometimes, atolls and lagoons protect a central island. Channels between islets connect a lagoon to the open ocean or sea.

Coral bleaching

Coral bleaching is the loss of intracellular endosymbionts (Symbiodinium, also known as zooxanthellae) through either expulsion or loss of algal pigmentation

Acidification

DEFINITION OF OCEANACIDIFICATION. Ocean Acidification(OA) is a term used to describe significant changes to the chemistry of the ocean. It occurs when carbon dioxide gas (or CO2) is absorbed by the ocean and reacts with seawater to produce acid

Fringing

It is distinguished from the other two main types (barrier reefs and atolls) in that it has either an entirely shallow backreef zone (lagoon) or none at all.

H+ ion

Medical Definition of hydrogen ion. 1: the cation H+ of acids consisting of ahydrogen atom whose electron has been transferred to the anion of the acid. 2: hydronium

Thermal expansion

Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases

Atmospheric CO2

a colorless, odorless, incombustible gas, CO 2, present in the atmosphereand formed during respiration, usually obtained from coal, coke, or natural gas by combustion, from carbohydrates by fermentation, by reaction of acid with limestone or other carbonates, or naturally from springs

Barrier

a coral reef running parallel to the shore but separated from it by a channel of deep water.

Antheropogenic

caused or produced by humans

Zooxanthellae

contain photosynthetic algae, called zooxanthellae, that live in their tissues. The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis.

Reef bulding

coral reef. A mound or ridge of livingcoral, coral skeletons, and calcium carbonate deposits from other organisms such as calcareous algae, mollusks, and protozoans. Most coral reefs form in warm, shallow sea waters and rise to or near the surface, generally in the form of a barrier reef, fringing reef, or atoll

pH

pH. Chemistry. 1. the symbol for the logarithm of the reciprocal of hydrogen ion concentration in gram atoms per liter, used to express the acidity or alkalinity of a solution on a scale of 0 to 14, where less than 7 represents acidity, 7 neutrality, and more than 7 alkalinity

Acidity

the level of acid in substances such as water, soil, or wine
