Composite Pb (lead) isotope record for Tropic Seamount (NERC Grant NE/M011151/1)
The file contains the LA-MC-ICP-MS composite Pb isotope ratios for Tropic Seamount, north-east Atlantic Ocean, spanning a deposition history covering the last 75 Ma. The record was obtained by analysis of hydrogenetic ferromanganese crust samples recovered during the 2016 JC142 expedition of the MarineE-Tech project.

Laser ablation work was performed using an Elemental Scientific Lasers NWR193UC laser ablation system with TV2 two-volume ablation cell, coupled to a ThermoScientific Neptune Plus MC-ICP-MS. Data were collected on a continuous, time-resolved, basis with data integrated every 0.262 seconds. Fe-Mn crust samples were analysed using a letter-box format ablation pattern of 15*150 µm continuously rastering at 10 µm/s perpendicular to the sample’s stratigraphy. Laser ablation Pb isotope ratios were normalised through standard bracketing using the Baker et al (2004) values for NodA-1. The laser ablation data is averaged every 20 integrations and consequently, each data point represents the Pb isotopic composition measured over 50 µm. Uncertainty for each averaged measurement is presented as the standard error of the 20 integrations propagated with Nod-A over-dispersion for the session.
