Deglacial radiocarbon history of tropical Atlantic thermocline waters: absence of CO2 reservoir purging signal

► Deglacial equatorial Atlantic thermocline was not anomalously very depleted 14C. ► Southern sourced water was invading deglacial equatorial Atlantic thermocline. ► Current hypothesis for the glacial CO2-rich/14C-depleted reservoir is questioned. ► Or deglacial intermediate circulation was different from today.
