We show here that the contrast \r\nin the oxygen isotopic composition of benthic foraminiferal tests \r\nacross the Florida Current is reduced during the Younger Dryas. \r\nThis most likely reflects a decrease in the density gradient \r\nacross the channel and a decrease in the vertical shear of the\r\nFlorida Current. This reduced shear is consistent with the \r\npostulated reduction in the Atlantic meridional overturning \r\ncirculation. We find that the onset of this change in density \r\nstructure and flow at the start of the Younger Dryas is very abrupt, \r\noccurring in less than 70 years.
