Tides. Tidal Characteristics. single waves - stretch across entire ocean basins. shallow-water waves wavelengths greatly exceed the depth of the ocean. complex interactions of moon and sun. Origin of the Tides.
Animation courtesy of NASA Goddard Space Flight Center: The Moon's gravity tugs at the Earth, causing ocean water to slosh back and forth in predictable waves called tides. We can visibly observe some of that energy dissipate at the beach, with waves rolling across coastal shallows and shoals. Most of the energy dissipates due to friction between the water and the shallow floor beneath it
Earth rotates from
W to E
Tidal bulge to W
Animation courtesy of NASA Goddard Space Flight Center: Using 6 years of data from TOPEX/Poseidon satellite altimeter, they derived a 16-day set of predictive data, showing a synthetic view of how the tides move around the world's oceans.
