The excel table presents the high-resolution LA-MC-ICP-MS Pb isotope data (± 2S%) produced for the Paleocene interval of Fe-Mn crust core sample 085_004 recovered in 2016 during the JC142 expedition to Tropic Seamount for the MarineE-Tech project. A detailed description of the sample can be found in Josso et al., 2019 and 2020. The Scripts data are Matlab and R readable file presenting all scripts and built-in functions used during the processing of the data to demonstrate the presence of astronomical imprint on the cyclicity of the Pb isotope ratios.
