| Barrier Island | long ridge of sand or other sediment deposited by longshore currents and separated from the mainland |
| Coriolis Effect | deflects moving particles such as air and water to the right above the equator and to the left below the equator |
| Surface Current | wind driven movement of ocean water that primarily affects the upper few hundred meters of the ocean |
| Density Current | movement of ocean water that occurs in depths too great to be affected by surface winds and is generated by differences in water temperature and salinity |
| Upwelling | cold, deep water upward movement of ocean water that occurs when winds push surface water aside and it is replaced with that originates on the ocean bottom |
| Gyre | any large system of rotating ocean currents, particularly those involved with large wind movements. |
| Ocean Currents | a continuous, directed movement of ocean water generated by breaking waves, wind, Coriolis effect, temperature and salinity differences and tides. |
| Estuary | costal area of brackish water formed where the lower end of a freshwater river or stream enters the ocean |
| Ocean Acidification | CO2, SO2, and NO emissions are making our oceans more acidic. |
