What is Loop Current?
[[File:Ocean currents 1943 Gulf Stream.jpg|thumb|[[Gulf Stream]] [[Ocean current|currents]] (1943 map).]] Part of the [[Gulf Stream]], the '''Loop Current''' is a warm ocean [[Ocean current|current]] in the [[Gulf of Mexico]] that flows northward between [[Cuba]] and the [[Yucatán Peninsula]], moves north into the Gulf of Mexico, loops west and south before exiting to the east through the [[Straits of Florida|Florida Straits]]. Around 1970, it was believed that the Loop Current exhibited an annual cycle in which the Loop feature extended farther to the north during the summer. Further study over the past few decades, however, has shown that the extension to the north (and the shedding of eddies) does not have a significant annual cycle. The Loop Current and its eddies may be detected by measuring sea surface level. Sea surface level of both the Eddies and the Loop on [[September 21]], 2005 was up to {{convert|60|cm|lk=on}} higher than surrounding water, indicating a deep area of warm water beneath them.<ref>{{Cite web |url=http://www.colorado.edu/news/releases/2005/366.html |title=CU-Boulder Researchers Chart Hurricane Rita Through Gulf of Mexico &#124; News Center &#124; University of Colorado at Boulder |access-date=2007-11-30 |archive-date=2006-06-17 |archive-url=https://web.archive.org/web/20060617171541/http://www.colorado.edu/news/releases/2005/366.html |url-status=dead }}</ref> ==References== {{reflist}} [[Category:Oceans]] [[Category:Tropical cyclones]] [[Category:Ocean currents]] {{geo-stub}}
