Global polychlorinated biphenyl (PCB) seawater observations between 1999 and 2013

Data provide a synthesis of peer-reviewed dissolved phase seawater measurements of polychlorinated biphenyl (PCB) concentrations. Data span the time period between 1999 and 2013 and are useful for benchmarking and evaluating model simulations. These data were compiled as part of an NSF funded project that aimed to investigate how changing global emissions and climate are affecting persistent organic pollutants in the Arctic. Citations to the original data sources are provided in the text file. Observations include both surface water measurements and vertical profiles. Data provided indicate total PCB concentration ('Tot'), filter passing PCB ('Aq') and filtered PCB ('Part').

本数据集整合了经同行评议的海水溶解相多氯联苯（polychlorinated biphenyl, PCB）浓度实测数据。数据时间跨度为1999年至2013年，可用于模型模拟的基准测试与性能评估。本数据集由美国国家科学基金会（National Science Foundation, NSF）资助的研究项目汇编而成，该项目旨在探究全球排放变化与气候变化如何影响北极地区的持久性有机污染物。原始数据来源的引用信息已在文本文件中提供。观测数据包含表层海水实测数据与垂直剖面数据两类。本次提供的数据涵盖总PCB浓度（'Tot'）、可滤过相PCB（'Aq'）与颗粒相PCB（'Part'）。
