| | Chandler's Wobble (Site not responding. Last check: 2007-10-13) |
 | | The wobble, named for its 1891 discoverer, Seth Carlo Chandler, Jr., an American businessman turned astronomer, is a wobbling motion exhibited by Earth as it rotates on its axis. |
 | | Over the years, things like atmospheric phenomena, continental water storage (changes in snow cover, river runoff, lake levels, or reservoir capacities), interaction at the boundary of Earth's core and its surrounding mantle, and earthquakes have benn believed to be the cause. |
 | | Richard Gross, a Jet Propulsion Laboratory geophysicist, reports that the principal cause of the Chandler wobble is fluctuating pressure on the bottom of the ocean, caused by temperature and salinity changes and wind-driven changes in the circulation of the oceans. |
