Earth's Wobble!   

In 1891 Seth Carlo Chandler discovered a small motion in the Earth's axis of rotation, a motion we call the Chandler wobble, today. The Chandler wobble is an example of the kind of motion that can occur for a spinning object that is not a sphere.

"The Earth rotates about its axis once a day, but does not do so uniformly. Instead, the rate of rotation fluctuates by up to a millisecond per day, and the Earth wobbles as it rotates. Much like the wobble of an unbalanced automobile tire, the Earth wobbles because the mass of the Earth is not balanced about its rotation axis." , as explains Richard Gross in his paper.

To measure the wobble, the International Latitude Observatories were established in 1899. today the monitoring is done by the International Earth Rotation Service. According to the observations, the wobble's amplitude has varied since its discovery. These variations had remained unexplained for about a century. On July 18th, 2000, the Jet Propulsion Laboratory announced that the fluctuating pressure on the bottom of the ocean seems to be the main cause of the Chandler wobble.

However there is more mystery to the wobble than these fluctuations.  An analysis of data from the past 160 years, shows 3 occasions of sudden and significant changes in the wobble. In the years 1830, 1920, and 2005 the wobble had a phase change of 180 degrees which seems to remain unexplained.
