ENRICH 2019 Trace element data (RV Investigator IN2019_V01 Southern Ocean voyage)

Trace element data collected from 18 stations near the Mertz Glacier on the 2019 ENRICH voyage. Sea water was collected using a 12-bottle trace metal rosette (TMR) and acidified for analysis back in Hobart. Samples were measured using an offline seaFAST pre-concentration system and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) at the University of Tasmania. This data contributed to Smith et al., Circumpolar Deep Water and shelf sediments support late summer microbial iron remineralisation in Global Biogeochemical Cycles (2021).

本数据集涵盖2019年ENRICH航次在默茨冰川（Mertz Glacier）附近18个站位采集的微量元素数据。研究团队采用12瓶式痕量金属采水器（trace metal rosette, TMR）采集海水样品，随后将样品运回霍巴特完成酸化处理以待后续分析。样品于塔斯马尼亚大学（University of Tasmania）借助离线seaFAST预浓缩系统与电感耦合等离子体质谱法（Inductively Coupled Plasma-Mass Spectrometry, ICP-MS）完成定量测定。本数据集为Smith等人2021年发表于《全球生物地球化学循环》（Global Biogeochemical Cycles）的论文《绕极深层水与陆架沉积物助力夏末微生物铁再矿化》提供了数据支撑。
