中国第13次北极科学考察(2023年)北极点断面站位海水颗粒有机碳(POC)分析数据

中国第13次北冰洋科学考察期间，于北冰洋进行颗粒有机碳含量调查，主要目的在于获得颗粒有机碳的基本分布特征，分析其变化规律及形成机制，研究研究海域的生物地球化学循环，以及物理、化学过程变动对生态系统的影响。 1.测量仪器 仪器名称：元素分析仪 仪器型号：Flash 2000HT 标定方法：使用尿素标准物质 2.观测方法和所获观测资料 2023年9月5日完成了北极点海域1个断面调查站位海水悬浮颗粒有机物的滤膜样品采样工作，并带回陆地实验室进一步测量。 3.观测区域 北极点海域。 4.质量描述 通过测样过程中标准物质的使用进行质量控制。 5.数据来源署名格式 （一）中国极地研究中心（中国极地研究所），Polar Research Institute of China）； （二）国家极地科学数据中心，National Arctic and Antarctic Data Center；During the 13th Chinese National Arctic Scientific Expedition, surveys of particulate organic carbon (POC) content were conducted in the Arctic Ocean. The primary objectives were to obtain the basic distribution characteristics of particulate organic carbon, analyze its variation patterns and formation mechanisms, investigate the biogeochemical cycles in the study area, and explore the impacts of physical and chemical process changes on the ecosystem. 1. Measuring Instruments Instrument Name: Elemental Analyzer Instrument Model: Flash 2000HT Calibration Method: Using urea certified reference material 2. Observation Methods and Obtained Observation Data On September 5, 2023, sampling of filter membrane samples for suspended particulate organic matter in seawater was completed at one transect survey station in the North Pole waters, and the samples were brought back to a land-based laboratory for further measurement. 3. Observation Area North Pole waters 4. Quality Description Quality control was carried out through the use of certified reference materials during the sample testing process. 5.
