C-iTRACE

Abstract

C-iTRACE is a coarse resolution (3˚), ocean-only simulation run from the LGM (22ka) to present day using iPOP2, the isotope-enabled ocean component of the CESM1. This simulation was developed in order to better understand ocean circulation and tracer evolution during the last deglaciation, and it does so by providing a direct comparison to paleo-ocean proxy records via the inclusion of isotope tracers and active biogeochemistry. C-iTRACE is forced with monthly heat, freshwater, and momentum fluxes from TraCE-21Ka. Simulated tracers include carbon isotopes, oxygen isotopes, Neodymium and Pa/Th. Further details about the C-iTRACE simulation can be found in Gu et al. 2019, 2020, 2021.
