Dynamic theory of tides is the modern theory of ocean tides that includes amphidromic circulation.[1][2][3][4][5][6][7][8][9][10] Since measurement have confirmed the theory, many things have possible explanations now, like how the tides interact with deep sea ridges and chains of seamounts give rise to deep eddies that transport nutrients from the deep to the surface.[11] The equilibrium tide theory calculates the height of the tide wave of less than half a meter, the dynamic theory explains why tides are up to 15 meters. [12]

The theory was developed by Pierre-Simon Laplace in 1775.[13] Satellite data has confirmed the Dynamic theory as accurate, and the tides worldwide are now measured to within a few centimeters.[14][15] Measurements from the CHAMP satellite closely matches the models based on the TOPEX data.[16][17] Accurate models of tides worldwide are essential for research, as the variations due to tides must be removed from SSH measurements when calculating gravity and changes in sea levels.[18]
