Tropical-eastern-Atlantic-Benthic-Foraminifera-analyses These scripts were used to process the benthic foraminifera (BF) data GeoB9512-5 of the tropical eastern Atlantic (TE Atlantic). This folder contains 2 codes to reproduce the results of the cited research. Folder 9512Age_PaleoOx contains the code and data to reproduce paleo-oxygenation results: Folder 9512Age_PaleoOx (For Manuscript xxx) 9512AgeModel_PaleOx.R was written in two parts. First Part: lines 16 - 154 to model ages based on the radiocarbon data published here https://doi.org/10.1594/PANGAEA.962899 and to estimate the median ages of the dissolved oxygen concentration calculated from the Enhanced Benthic Foraminifera Oxygen Index; and the proxy uncertainties Second part: from lines 156 - 889, to visualize the results presented in the publication the 9512_EA.csv file was adapted for this code using Supplementary Information 2 and 3 This includes the global variables compiled and plotted in Figures 2 and 3. Line 196: Figure 2 Line 434: Figure 3 Line 725: Figure 6 All necessary files are provided in the folder. Any inquiries can be directed to the corresponding author.
