TIDES
This has the greatest influence on tides.
The moon
Driven by global winds
Surface currents
Forms when something falls into the ocean
Splash wave
Winds blowing from the east
Trade winds
The only current that is a continuous line.
Antarctic cirumpolar current
In a 24 hour period, most places observe this many tides.
4 (2 high and 2 low)
A counter-clockwise gyre is located here
Southern hemisphere
The vertical distance between a wave’s crest and trough
Wave Height
As wind blows over the water, this force moves the waves.
Friction
This reduces wave erosion
Groin
When celestial bodies are aligned.
Spring Tide
These two things affect density currents
Temperature and salinity
When a crest peaks sharply and then falls over, it creates this kind of wave.
Breaker
Strong winds from this type of storm bring unusually high tides.
A swirling motion that can occur when there is a branch off of a gyre is known as
eddies
This is a lower than usual tide during the quarter moons
Neap tide
This combines the influences of the Coriolis effect, current speed, and water depth to change the direction of a current
Ekman Spiral
Distance over which a steady wind blows as it creates waves
Fetch
These winds bring ocean waters to the west.
Trade winds
Sea level is higher than usual, has less nutrients and more oxygen
Downwelling
These four things affect tides
Shape of the coastline
Size of the continental shelf
Depth of ocean basin
Position of the moon
This is a narrow current that flows eastward along the equator between the two main equatorial currents
Equatorial countercurrents
The deepest depth of the ocean that is affected by a wave.
wave base
This wind carries the Gulf Stream
Prevailing winds
Caused by the rotation of the earth
Coriolois affect
