The bond between two amino acids formed when a carboxyl (-COOH) group of one amino acid joins an amino (-NH2) group of another amino acid, releasing water in the process.
Industry:Natural environment
The level to which the water rose on an average day over a previous period of time (years or decades); the average of all the high tides as calculated over a long period of time.
Industry:Natural environment
The science of measuring ocean depths to determine the topography of the sea floor.
Industry:Natural environment
A coral polyp tentacle that has an increased number of nematocysts and elongates in order to 'sting' neighboring corals and sessile invertebrates. A tool in the competition for space and resources.

Industry:Natural environment
An area of land that drains downslope to the lowest point. The water moves through a network of subterranean and surface drainage pathways which converge into streams and rivers, eventually reaching an estuary and finally the ocean. Because water moves downstream, any activity that affects the water quality, quanity, or rate of movement at one location can affect locations downstream to the ocean and out to coral reefs.
