Seagrass soils sequester the equivalent of up to half the metal emissions by one of the world’s largest smelters [dataset]

The database compiles published data (in Lafratta et al. 2023, Marine Pollution Bulletin) on physical, biogeochemical and chemical characteristics (coordinates, cm compressed and decompressed, dry weight (DW), dry bulk density (DBD), Pb, Zn and Cd concentrations analysed at Edith Cowan University (ECU), Pb, Zn and Cd concentrations analysed at University Autonoma of Barcelona (UAB), final Pb, Zn and Cd concentrations, organic carbon content (%), < 63 µm sediment particles content (%) and Pb isotopes ratio) of soils underneath Posidonia australis seagrass meadows in Port Pirie, South Australia. Cumulative dry mass, total and excess Pb-210 concentrations are also included. The dataset includes data for a total of twelve cores (PP1, PP2, PP3, PP4, PP5, PP6, PP7, PP8, PP9, PP11 and A15) plus two addition cores (PP10 and PP12) for which only raw data of metal concentrations are provided, as per associated manuscript.
For the twelve main cores, values in black represent the “operating period”, while values in blue represent the “pre-operation period” (check associated manuscript for details).

本数据库汇编了Lafratta等人2023年发表于《Marine Pollution Bulletin》（《海洋污染公报》）的已公开数据，涵盖澳大利亚南澳大利亚州皮里港澳洲波喜荡（Posidonia australis）海草床下方沉积物的物理、生物地球化学与化学特征，包括采样坐标、压缩与未压缩状态下的厘米尺度参数、干重（DW）、干容重（DBD）、埃迪斯科文大学（ECU）分析的铅（Pb）、锌（Zn）与镉（Cd）浓度、巴塞罗那自治大学（UAB）分析的铅、锌与镉浓度、最终铅锌镉浓度、有机碳含量（%）、粒径小于63 μm的沉积物颗粒占比（%）以及铅同位素比值。本数据集同时纳入累积干质量、总铅-210与过剩铅-210浓度数据。
本数据集共计包含12根主岩芯（PP1、PP2、PP3、PP4、PP5、PP6、PP7、PP8、PP9、PP11与A15），另有2根补充岩芯（PP10与PP12），根据相关手稿要求，仅提供其金属浓度原始数据。
针对12根主岩芯，黑色数值代表"运营期"数据，蓝色数值代表"运营前期"数据，详细信息请参阅相关手稿。
