An 800-kyr planktonic 𝜹18O stack for the Western Pacific Warm Pool

Our 10 core planktonic 𝜹18O WPWP stack is available as the "WPWP_planktonic_stack.txt" file, which contains the age, mean 𝜹18O, and 1 sigma 𝜹18O alignment uncertainty. The same file is also available under the name "stack.txt" in the Output folder. The stack was produced using alignment software BIGMACS (Lee and Rand et al., 2022).
The previously published depth and planktonic 𝜹18O as well as any radiocarbon or additional age constraints for each core used during stack construction can be found in the Inputs folder. This study's BIGMACS produced age models, depth, and planktonic 𝜹18O data for each core can be found in the Outputs folder under the "results.mat" file or as .txt files in the individual folders named for each core.
Additional BIGMACS input and output files for planktonic 𝜹18O from Timor Sea (near the WPWP) core MD01-2378 (Holborn et al., 2005) are provided to demonstrate the alignment and age model differences between using the our new regional planktonic 𝜹18O WPWP stack and the global benthic 𝜹18O LR04 stack as alignment targets.  Differences between the two stacks during MIS 3 and 4 produce a ~17 kyr error in the alignment of the core to the LR04 stack at ~77 kyr ago (depth 8.81 m in core MD01-2378). Because the planktonic 𝛿18O records near the WPWP share features which differ from those of benthic 𝛿18O, age model results are expected be more accurate when these planktonic 𝛿18O records are aligned to the WPWP stack than to a benthic stack.
