North Atlantic benthic d18O stack data

Files containing the data for our speleothem-tied North Atlantic benthic d18O stack, including: ages, d18O values, d18O err, age samples output by BIGMACS, and the composite depth scale used for this stack (based on IODP site U1308). Please read for information on what each file contains:'NA-stack_age-samples.txt' = 1000 sets of age model samples generated during stack construction, each column contains a unique age model. 'NA-stack_age-d18O.txt' = the median age model output by BIGMACS after stack construction with their corresponding d18O data points (this age model closely aligns with that of the LR04 stack since the LR04 stack was used as our initial alignment target). 'NA-stack_depth_composite.txt' = the composite depths used to reduce bias in our stack's age model. 'NA-stack_untuned_age_model.txt' = the stack ages after mapping them onto the composite depth scale of Site U1308. This is the data plotted in Fig. 3 of the paper. This file was added on February 3, 2025 to allow users to download this data directly without having to apply the extra step of interpolating the median age model onto the depth scale themselves.
