Late Cretaceous to Miocene multi‐proxy (foraminifer Mg/Ca, δ18O, ∆47, and Sr/Ca, and biomarker TEX86H, MATmrs) low-resolution paleotemperature record from ODP Leg 174AX, Bass River site, New Jersey Shelf, North Atlantic ...

We present a multi‐proxy (foraminifer Mg/Ca, δ18O, ∆47, and Sr/Ca, and biomarker TEX86H, MATmrs) low-resolution paleotemperature record based on seven sets of high‐resolution time series from the late Cretaceous to Miocene from the Ocean Drilling Program Bass River site, New Jersey Shelf, North Atla...

Description
Summary:We present a multi‐proxy (foraminifer Mg/Ca, δ18O, ∆47, and Sr/Ca, and biomarker TEX86H, MATmrs) low-resolution paleotemperature record based on seven sets of high‐resolution time series from the late Cretaceous to Miocene from the Ocean Drilling Program Bass River site, New Jersey Shelf, North Atlantic. Along with insight into long‐term climate evolution, this allows testing for internal consistency between proxies. The bottom water temperatures (BWT) reconstructed using benthic δ18O and Mg/Ca-values show good agreement in recorded trends with the TEX86H sea surface and shallow subsurface temperature record, and with the stacked global benthic oxygen isotope record. The Mg/Ca-based BWTs are higher than the δ18O-based BWTs, likely due to uncertainty in the assumptions associated with the Mg/Ca calibration to sea water Mg/Ca. Absolute δ18O-based BWT reconstructions are supported by clumped isotope paleothermometry. The agreement in main trends of the independent paleotemperature proxies indicates that the ... : Supplement to: de Bar, Marijke W; de Nooijer, Lennart Jan; Schouten, Stefan; Ziegler, Martin; Sluijs, Appy; Reichart, Gert-Jan (2019): Comparing sea water temperature proxy records for the past 90 Myrs from the shallow shelf record Bass River, New Jersey.
