  9. Comparison

  10. History of Tidal Prediction

  11. The first to claim tidal predictions in Britain was John Wallingford around 1213. He used the different phases of the moon to predict the “spring” and “neap” tides.

  12. Sir Isaac Newton’s discovery of gravity led to the equilibrium theory of tides.

  13. 1873 First tide predicting machine.

  14. In 1928 the Germans improved the tide prediction engine. This stayed in widespread usage until the 1960’s.

  15. Southeast Alaska Natives • The Raven brought the sun, moon and stars. • The Tide Woman agreed to provide low tides for food. • They used the phases of the moon to understand the extreme high and low tides.
