aquaculture: the science and business of raising and harvesting fish in a controlled situation
brackish: a mixture of freshwater and saltwater
chemosynthesis: process by which some organisms, such as certain bacteria, use chemical energy to make food
cold seeps: places on the seafloor where minerals flow out of the earth through the ocean bottom
concentration: the amount of a substance that is contained in another substance
deep: currents that move water far below the surface caused by differences in density
desalination: the process of removing salt from ocean water to obtain fresh water
drought: a long period of abnormally low amounts of precipitation
downwelling: the movement of water from the surface to greater depth
ecotourism: tourism that encourages environmental awareness and benefit an ecosystem
estuary: the area where a freshwater stream or river merges with the ocean
hydrothermal vents: an opening in the sea floor from which heated water rises and mixes with the ocean water above
nonpoint source: pollution with a source that is hard to find or scattered
photic zone: the narrow top slice of the ocean, where light permeates sufficiently for photosynthesis to occur
point source :pollution that enters water from a known source.
salinity: a measure of the amount of dissolved salts in a given amount of liquid.
septic system: collects wastewater often for one home or business and uses an underground tank to
sewer system: used to collect and treat wastewater from a city or a town.
specific heat: the heat required to raise the temperature of one gram of a substance one degree centigrade
surface: currents that move water at the top layer of the ocean caused by winds
sustainable: able to meet the current demand for a resource without depleting the future supply
upwelling: the movement of deep, cold, and nutrient-rich water to the surface
