| Salinity | the measure of all the salts dissolved in water. |
| Upwelling | an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water. |
| Gyre | any large system of rotating ocean currents, particularly those involved with large wind movements. |
| Wave Height | the difference between the elevations of a crest and a neighboring trough. |
| Wavelength | the distance between waves. |
| Thermocline | a thin but distinct layer in a large body of fluid in which temperature changes more rapidly with depth than it does in the layers above or below. |
| Global Conveyor Belt | a constantly moving system of deep-ocean circulation driven by temperature and salinity. |
| Tide | the cycle of rising and falling of the surface of bodies of water caused by the attraction of the moon and the sun. |
| Spring Tide | A tide in which the difference between high and low tide is the greatest. |
| Neap Tide | A tide in which the difference between high and low tide is the least. |
| Longshore Current | an ocean current that moves parallel to shore. |
| Pycnocline | a layer in a body of water where the density is the greatest. |
