Oceanography Review

2. _________ latitude zones have the most dense surface water, since UV radiation is minimal.
3. The full and new moon phases result in the highest tides, also called ______ tides.
5. _________ currents are driven by different water densities, while surface currents are driven by wind and the Coriolis effect.
6. While nekton can swim independently on their own, these creatures rely on currents for movement.
9. Due to the UV intensity from the sun, _____ latitude zones have high surface water temperatures.
10. First quarter and last quarter moon phases result in the the lowest tides, also known as ______ tides.
12. In order for a species to not be overfished, this needs to be established (three words).
15. Warm, less salty water floats on top of cold, more salty water because it is less _______.

1. Minerals in ocean water come from volcanoes and vents, some marine organisms, and also this process (two words).
4. These organisms, along with seaweed, are the most efficient feeders and can help restore damaged ecosystems.
7. The _______ zone has the highest level of biomass and biodiversity in the ocean.
8. This process brings nutrients up from the deep, which in turn help algae and plankton.
11. Approximately how many hours are there from one high tide to the next high tide?
13. This deep, cold and high pressure area of our ocean is devoid of sunlight-therefore, it does not accommodate a lot of life.
14. Ocean water is approximately __.5% dissolved minerals (spell out number).
