Stable isotope record of benthic foraminifera in sediment cores in the oceans, supplement to: Oppo, Delia W; Fairbanks, Richard G (1987): Variability in the deep and intermediate water circulation of the Atlantic Ocean during the past 25.000 years: Northern Hemisphere modulation of the Southern Ocean. Earth and Planetary Science Letters, 86(1), 1-15
The relative flux of North Atlantic Deep Water (NADW) out of the Atlantic can be monitored in the Southern Ocean, where high delta13C NADW mixes rapidly with low delta13C recirculated Pacific water before forming Antarctic Bottom Water (AABW). By using delta13C measured in benthic foraminifera as a...
