Caballero Gill, Rocio P.; Clemens, Steve; Prell, Warren (2012): Antarctic isotope maxima events 24 and 25 identified in benthic marine delta (super 18) O. American Geophysical Union, Washington, DC, United States, Paleoceanography, 27 (1), georefid:2013-008064

Abstract:
High-resolution planktic and benthic delta (super 18) O records at Site 1146 (northern South China Sea) include structure within Marine Isotope Stage 5.4, 118.5-105.9 ka, that is not captured in stacked delta (super 18) O records commonly used for age model construction and as proxies for global ice volume. Leveraging a common monsoonal influence, Site 1146 planktic delta (super 18) O was aligned to speleothem delta (super 18) O from southeastern China to derive a radiometrically calibrated (RC) age model. On the RC age model, the benthic delta (super 18) O record contains structure equivalent in time to Antarctic Isotope Maximum (AIM) events 24 and 25. Sea level reconstructions for isotopic event 5.4 suggest that these benthic delta (super 18) O events (AIM 24 and 25) derive from isotopic change (ice volume) although some temperature change cannot be completely excluded.
