The loss of color in corals due to the expulsion of zooxanthellae under stress conditions.

Ocean Acidification

The decrease in pH of ocean waters caused by the uptake of carbon dioxide from the atmosphere.

Coral Reefs and Salinity

Coral require stable salinity levels for osmotic balance; fluctuations can lead to stress.

Depth for Light Penetration

Corals thrive at depths where adequate sunlight reaches them for photosynthesis.

Belt Transect

A strip of land where researchers measure and record species abundance and environmental features.
