Uncertainties in seawater thermometry deriving from intratest and interest Mg/Ca variability in Globigerinoides ruber.

Sadekov, Aleksey; Eggins, Stephen; De Deckker, Patrick; Kroon, Dick


Laser ablation inductively coupled plasma-mass spectrometry microanalysis of fossil and live Globigerinoides ruber from the eastern Indian Ocean reveals large variations of Mg/Ca composition both within and between individual tests from core top or plankton pump samples. Although the extent of intertest and intratest compositional variability exceeds that attributable to calcification temperature, the pooled mean Mg/Ca molar values obtained for core top samples between the equator and >30°S...[Show more]
