High-resolution LA-MC-ICP-MS Pb isotope data (65.5 - 63 Ma) for Tropic Seamount, north-east Atlantic, and Matlab and R processing scripts for cyclostratigraphic analysis (NERC Grant NE/M011151/1)
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.

Data Quality
The Pb isotope data was generated by laser ablation and analysed on a Neptune MC-ICP-MS at the British Geological Survey. Data were acquired in continuous transects using a letterbox format (2*150 µm) ablation spot rastering perpendicular to the sample layering at 2 µm/s with one integration every 0.262 seconds. Data were normalised to Nod-A (Baker et al., 2004) as the primary reference material and the data output at the integration level for plotting as a continuous profile. Nod-P, JMn-1 and an in-house material (HRM) prepared from a homogenised quantity of Fe-Mn crust from Tropic Seamount, were analysed during the same sessions to validate the results by comparison to published and/or in-house results determined by solution calibration.
