| Description: |
This research shows the signature of a specific, sub-monthly ocean current fluctuation on the Earth's rotation rate, coinciding with recently-reported anomalies which developed in southeast Pacific surface temperature and bottom pressure fields during late 2009. The results show that concurrent variations in the Antarctic Circumpolar Current were strong enough to cause a detectable change in length-of-day following the removal of atmospheric angular momentum computed from the Modern Era Retrospective Analysis for Research and Applications database.
