Anaerobic bacteria -- Bacteria that respire in the absence of free oxygen.
Anion -- A negatively charged ion such as Cl- (chloride).
Anoxic -- The absence of free oxygen.
Atom -- The smallest component of an element, comprising neutrons, protons, and electrons.
Cation -- A positively charged ion, such as K+ (potassium) and Na+ (sodium).
Conservative property -- A property of water that is unaffected by biological processes and, consequently, remains stable over time.
Covalent bond -- The linkage of atoms in a molecule by sharing electrons.
-Deep layer
-Density
-Gas
Groundwater -- Water beneath the ground surface that seeped into the soil and rock from above.
Halocline -- A zone in the water column where the vertical change of salinity is relatively sharp.
Heat capacity -- A measure of the quantity of heat needed to raise the temperature of one gram of a substance by 1 degree C.
Hydrologic cycle -- The exchange of water among the ocean, atmosphere, and land by such processes as evaporation, precipitation, surface runoff, and groundwater percolation.

Ion -- An atom or molecule having an electrical charge because of a gain or loss of electrons.
Kinetic energy -- Energy of motion.

Molecule -- Two or more atoms that constitute the smallest component of a compound while retaining its chemical characteristics.
Nonconservative property -- A property of water that changes over time because it is affected by biological activity. Carbon dioxide and oxygen, which are used and produced by organisms, are examples of this kind of substances in seawater.
Nutrient -- Chemical compounds required by plants for normal growth;...
