These values are calculated using the measured concentrations of 230Th, 232Th and 238U, and assuming that all 232Th is detrital in origin. It also assumes a detrital 238U/232Th ratio of 0.7. In nature, this ratio can be variable. Concentrations are corrected for decay since deposition. 230Th-norm flux refers to the 230Th-normalized bulk sediment mass accumulation rate (or flux). 232Th flux refers to the 230Th-normalized flux of Thorium-232. This flux is calculated as 230Th-norm flux * 232Th (micro g/g) Note that 232Th (micro g/g) = 232Th (dpm/g) * (1/246186) * 10^6 Please refer to Francois et al. (2004) for more detail on this proxy. Note that the 230Th xs,o data of cores ME0005-24JC and TR163-31P given here differ slightly from those originally published by Kienast et al. 2007 due a) the use of an updated age model here and b) a minor spread sheet error in the earlier publication. Neither update affects the conclusions reached in the earlier study in any way. For core V19-30, 230Th, 232Th, and 238U data can be found in Hayes et al. 2010. ABSTRACT SUPPLIED BY ORIGINATOR: Sea surface temperatures (SST) and inorganic continental input over the last 25,000?years (25?ka) are reconstructed in the far eastern equatorial Pacific (EEP) based on three cores stretching from the equatorial front (~0.01°N, ME0005-24JC) into the cold tongue region (~3.6°S; TR163-31P and V19-30). We revisit previously published alkenone-derived SST records for these sites and present a revised chronology for V19-30. Inorganic continental input is quantified at all three sites based on 230Th-normalized fluxes of the long-lived continental isotope thorium-232 and interpreted to be largely dust. Our data show a very weak meridional (cross-equatorial) SST gradient during Heinrich Stadial 1 (HS1, 18–15?ka?B.P.) and high dust input along with peak export production at and north of the equator. These findings are corroborated by an Earth system model experiment for HS1 that simulates intensified northeasterly trade winds in the EEP, stronger equatorial upwelling, and surface cooling. Furthermore, the related southward shift of the Intertropical Convergence Zone (ITCZ) during HS1 is also indicative of drier conditions in the typical source regions for dust.
