Links between salinity variation in the Caribbean and North Atlantic thermohaline circulation / Matthew W. Schmidt, Howard J. Spero, David W. Lea.

Title: Links between salinity variation in the Caribbean and North Atlantic thermohaline circulation / Matthew W. Schmidt, Howard J. Spero, David W. Lea.
Author(s): Schmidt, Matthew W.

Lea, David W.
Date: 2004.
In: Nature. (2004.), Vol. 428(6979) (2004)
Abstract: Analyses two Caribbean sea sediment cores, combining Mg/Ca palaeothermometry with measurements of oxygen isotopes in foraminiferal calcite to reconstruct tropical Atlantic surface salinity during last glacial cycle. Notes that strength of North Atlantic thermohaline circulation, variations in which have been linked to rapid climate changes during last glacial cycle, depends on supply of warm, salty water from further south. Finds Caribbean salinity oscillated, covarying with strength of North Atlantic Deep Water formation, decreasing abruptly at initiation of Bølling/Allerød warm interval 14.6 kyr ago. Suggests advection of excess salt from Caribbean, and possibly Indian Ocean, into North Atlantic amplified thermohaline circulation (countering effects of North Atlantic surface warming, sea-ice retreat and deglaciation) and contributed to high-latitude warming in this period.
