Pathways and processes controlling the distribution of anthropogenic lead in the interior of the Southern Ocean

Repository overview This repository contains the numerical data associated with the GEOTRACES GS01 section between Australia and Antarctica as reported by Griffiths et al. (2026). It includes: (1) discrete seawater Pb concentration and Pb isotope data, together with associated hydrographic properties and assigned water mass classification (Griffiths et al 2026 GS01 Pb data.csv); and (2) high-resolution CTD profile sensor data for the corresponding stations (Griffiths et al 2026 SR3 hydrographic data.csv). The README file provides detailed information about each dataset.存储库概览 本存储库收录了由Griffiths等人（2026年）发布的、关联于澳大利亚与南极洲之间全球海洋示踪剂计划（GEOTRACES）GS01断面的数值数据。具体包含：(1) 离散海水样品的铅（Pb）浓度与铅同位素数据，以及配套的水文参数与已确定的水体团分类结果（Griffiths et al 2026 GS01 Pb data.csv）；(2) 对应站位的高分辨率温盐深（Conductivity, Temperature, Depth，简称CTD）剖面传感器数据（Griffiths et al 2026 SR3 hydrographic data.csv）。 本存储库的README文件提供了各数据集的详细说明。
