How Global Ocean Tides Work

Ocean tides aren't simple.
If Earth didn't have continents, tides would be huge bulges of water moving westward with the moon and sun.
This cool animation shows tides as a mix of waves spinning and getting trapped at different speeds.
Waves mostly flow freely westward, only near Antarctica.
But even there, it gets tricky as waves come together or split under Antarctic ice.
In the North Atlantic, waves mostly swirl counterclockwise, smaller in the middle of the ocean but bigger near the edges, especially near northwest Europe and Britain.
Waves go round and round New Zealand, making high tide on one side and low tide on the other.
Special satellites like Topex/Poseidon and Jason were sent to study this. They acted like flying tide meters.
After years of gathering data, scientists figured out how tides work in different places.
With this info and knowing exactly where the Sun and Moon are, we can predict tides anywhere, anytime.
The video shows data from a bit more than a day, and the tide levels are exaggerated to help us see how they change worldwide.
