Comparison of the productivity index estimated by Wienberg et al. ( 2010 ) and the planktonic δ ¹³ C record of the sediment core Geob 9064 (this study) with proxies related to trade wind and upwelling activity (planktonic δ ¹⁸ O and aeolian input). The planktonic δ¹³C values of the core MD04-2805CQ (Penaud et al. 2010) are displayed to establish comparison with nearby location. YD: Younger Dryas; HE: Heinrich Event; LGM: Last Glacial Maximum.
