Terms | Definitions |
|---|---|
 Pacific Ocean | The largest ocean |
| Atlantic Ocean | Half the size of the Pacific Ocean, also the second largest ocean |
| Indian Ocean | The third largest ocean |
| Artic Ocean | The smallest ocean |
| Salinity | The measure of the amount of dissolved solids in a given amount of liquid |
| Surface Zone | The warm, top layer of ocean water. It can extend to 300 m below sea level. Sunlight heats the top 100 m of the surface zone. Surface currents mix the heated water with cooler water below |
| Thermocline | The second layer of ocean water. It can extend from 300 m below sea level to about 700 m below sea level. In this part of the ocean, temperature drops with increased depth faster than it does in the other two zones. |
| Deep Zone | The bottom layer that extends from the base of the thermocline to the bottom of the ocean. The temperature in this zone can range from 1ºC to 3ºC. |
| Sonar | An acronym that stands for Sound Navigation And Ranging. Based on the echolocation of bats |
| Seasat | A type of satellite that allows scientists to measure speed and direction of an ocean current. Launched in 1978. |
| Geosat | A satellite used to measure slight changes in height of ocean's surface. |
| Bathymetric Profile | A map of the ocean floor that shows the ocean depth by using sonar signals. |
| Continental Shelf | The gently sloping section of the continental Margin located between the shoreline and the continental slope. |
| Continental Slope | The steeply inclined section of the continental Margin located between the continental rise and the continental shelf. |
| Continental Rise | The gently sloping section of the continental margin located between the continental slope and the abyssal plain. |
| Abyssal Plain | A large, flat, almost level area of the deep-ocean basin. |
| Continental Margin | Made up of continental crust |
| Deep-ocean Basin | Made up of oceanic crust |
| Mid-ocean Ridge | A long, undersea mountain chain that forms along the floor of the major oceans |
| Rift Valley | A long, narrow valley that forms as tectonic plates separate |
| Seamount | A submerged mountain on the ocean floor that is at least 1,000 m high and that has a volcanic origin |
| Ocean Trench | A steep, long depression in the deep-sea floor that runs parallel to a chain of volcanic islands or a continental margin |
| Deep Flight | The goal of this project is to explore the deepest part of the ocean |
