We provide high-resolution foraminiferal stable carbon isotope (d13C) records from the subarctic Pacific and Eastern Equatorial Pacific (EEP) to investigate circulation dynamics between the extra-tropical and tropical North Pacific during the past 60 kyr. We measured the d13C composition of the epibenthic foraminiferal species Cibicides lobatulus from a shallow sediment core recovered from the western Bering Sea (SO201-2-101KL; 58°52.52' N, 170°41.45' E; 630 m water depth) to reconstruct past ventilation changes close to the source region of Glacial North Pacific Intermediate Water (GNPIW). Information regarding glacial changes in the d13C of sub-thermocline water masses in the EEP is derived from the deep-dwelling planktonic foraminifera Globorotaloides hexagonus at ODP Site 1240 (00°01.31' N, 82°27.76' W; 2921 m water depth). Apparent similarities in the long-term evolution of d13C between GNPIW, intermediate waters in the eastern tropical North Pacific and sub-thermocline water masses in the EEP suggest ... : Supplement to: Max, Lars; Rippert, Nadine; Lembke-Jene, Lester; Mackensen, Andreas; Nürnberg, Dirk; Tiedemann, Ralf (2016): Evidence for enhanced convection of North Pacific Intermediate Water to the low-latitude Pacific under glacial conditions.
