Across
  1. 3. Ocean water that sinks due to higher density.
  2. 5. Vertical column of ocean water, divided into different zones according to their depth.
  3. 8. Regular rising and falling of Earth’s surface waters twice a tidal day; this is the result of the gravitational attraction of the Moon and Sun on Earth.
  4. 13. Chemical that will react with the pollutant is pumped into the plume to neutralize it.
  5. 15. Strong surface current that returns to the ocean from the shore.
  6. 18. Highest water levels during a day; high tides are caused by the gravitational pull of the Moon.
  7. 20. The difference between the high and low tide in a day.
  8. 21. Smallest tidal range in a lunar month; this coincides with the first- and third-quarter moons when the Sun and Moon are at 90o relative to each other.
  9. 22. Diseases that spread through freshwater sources.
  10. 25. Large tidal range that occurs when the Moon, Sun, and Earth area aligned; this happens at full and new moon phases.
  11. 26. Total mass of living things in a given region.
  12. 28. U.S. federal law that set water quality standards.
  13. 33. Different types of organisms in a given region.
  14. 34. Correcting a problem.
  15. 37. Water that is pushed onto a shoreline by a storm.
  16. 38. Open ocean, where sunlight does not reach the seabed.
  17. 39. Local surface currents that move along a shoreline in the direction of prevailing winds.
  18. 40. Highest point of a wave.
Down
  1. 1. Horizontal distance between two waves; wavelength is measured from crest to crest or trough to trough.
  2. 2. Apparent deflection of a freely moving object like water or air because of Earth's rotation.
  3. 4. Light created by organisms from chemical reactions.
  4. 6. Powerful chemicals used to disperse oil that has been spilled in a body of water.
  5. 7. Vertical extent of a wave.
  6. 9. Cold, nutrient-rich water that rises from oceanic depths.
  7. 10. Resource that is used faster than it can be made.
  8. 11. Change in the shape of water caused by energy from wind.
  9. 12. Horizontal movement of ocean water, caused by surface winds.
  10. 14. Organism that causes disease.
  11. 16. Microorganisms engineered to consume a contaminant; these organisms are injected into a pollutant plume to consume the toxins.
  12. 17. Mass per unit volume.
  13. 19. Measure of the amount of dissolved salt in water; average ocean salinity is 3.5%.
  14. 23. Zone in the water column deeper than 200 m where sunlight does not penetrate.
  15. 24. Ocean currents that travel vertically up and down; this water also travels deeper in the ocean.
  16. 27. Part of the ocean closest to the shore, between low and high tide.
  17. 29. Water that has been used for washing, flushing, or manufacturing.
  18. 30. Lowest water levels during a day; these occur when high tide is one-quarter of the way around Earth’s sphere.
  19. 31. Lowest point of a wave.
  20. 32. Five seawater loops created by surface ocean currents.
  21. 35. Part of the ocean where the continental shelf gradually slopes seaward; sunlight can penetrate to the bottom in much of the neritic zone.
  22. 36. Upper 200 m of the ocean, where sunlight penetrates.
