中国第38次南极科学考察(2021-2022年)南大洋沉积物微量元素分析数据

2021-2022年中国第38次南极科学考察期间，通过南极半岛、普里兹湾、罗斯海海域水体及沉积物的油类、微塑料、持久性有机污染物调查，从多个角度认识南极半岛、普里兹湾、罗斯海的污染物分布情况，揭示极地污染物的分布特征、主要来源和迁移路径，评估南极区域污染物对环境的影响及生态效应，为我国在处理国际海洋污染物问题提供研究基础与技术支撑。 本数据为第38次南极科学考察(2021-2022年)沉积物微量元素分析数据，数据内容包括站位、经度、纬度、日期、水深、铜、铅、锌、镉、铬、汞、砷等。 1.样品采集设备 （1）箱式采泥器 （2）高通量固相萃取系统 2.观测区域 本航次考察海区南极半岛、普里兹湾、罗斯海海域。During the 38th Chinese Antarctic Scientific Expedition conducted from 2021 to 2022, surveys targeting oil pollutants, microplastics, and persistent organic pollutants (POPs) were carried out in water bodies and surface sediments of the Antarctic Peninsula, Prydz Bay, and Ross Sea. This study aims to comprehensively characterize the pollutant distribution in these three polar sea areas, uncover the distribution features, primary sources and migration routes of polar pollutants, evaluate the environmental impacts and ecological effects of pollutants in the Antarctic region, and provide research foundations and technical support for China to handle international marine pollution-related issues. This dataset comprises trace element analysis data of sediments collected during the 38th Chinese Antarctic Scientific Expedition (2021–2022). The data fields include sampling station, longitude, latitude, collection date, water depth, and concentrations of elements including copper (Cu), lead (Pb), zinc (Zn), cadmium (Cd), chromium (Cr), mercury (Hg), arsenic (As), and others. 1. Sample Collection Equipment (1) Box sampler (2) High-throughput solid-phase extraction system 2. Survey Area The sea areas covered in this expedition are the Antarctic Peninsula, Prydz Bay, and Ross Sea.
