Sedimentological data from the Limpopo River Basin dams, southern Africa, 2018-2021

The data set contains grain size distributions, organic matter (OM) content and trace metal distribution (including Fe, Zn, Cu, Cr and Pb) of 37 shallow cores of sediments sampled from dams across the Limpopo River Basin. The dams include: Gaborone, Lotsane and Shashe dams in Botswana; Houtrivier, Nwanedi and Mutshedzi dams in South Africa; Ripple Creek and Zhovhe dams in Zimbabwe; and Massingir Dam in Mozambique. Data from two cores sampled from an oxbow lake in Mozambique are also included. The cores were collected with a gravity corer using PVC pipes of 5 cm diameter by a team from Botswana International University of Science and Technology (BIUST) led by Dr. Franchi between July 2018 and April 2021.

本数据集收录了来自林波波河流域各处水坝的37个浅层沉积物样品的粒径分布、有机质（OM）含量以及微量元素分布（包括铁、锌、铜、铬和铅）。涉及的坝体包括：博茨瓦纳的加博罗内、洛桑尼和沙沙坝；南非的豪特里维尔、恩瓦内迪和穆特谢齐坝；津巴布韦的瑞普利溪和卓维赫坝；以及莫桑比克的马辛吉尔大坝。此外，还包括从莫桑比克一个叉河湖中采集的两个样品的数据。这些样品采用重力钻芯法，使用直径为5厘米的PVC管收集，由博茨瓦纳国际科技大学（BIUST）的弗朗奇博士领导的团队于2018年7月至2021年4月期间进行采集。关于此数据集的详细信息，请参阅https://doi.org/10.5285/b8db8239-3bde-454a-aa75-d1cec24c8763。
