- a A measure of the amount of dissolved salts in a given amount of liquid. It can be written as salinity = 35 parts per thousand, or 35%.
- b The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.
- c Dissolved solids that make up about 3.5% of the mass of ocean water. These dissolved solids give the ocean its salty taste.
- d Extends into the deep waters beyond the continental shelf.
