Something not found in your tide tables

Today's Tides are Unusually High

In THIS ARTICLE the author argues that plate tectonics affects tides. This is not particularly surprising but he goes on to argue that, because of its size, the Atlantic has larger tides than would otherwise occur. So the amount of energy in tides is a maximum at present and stirs the oceans greatly. The subsequent movement of heat and salts has profound effects on ocean currents and biological production. Fortunately for us the present high energy regime will persist for the next 18 million years.
