Arctic Ocean - Contaminants aggregated datasets 1974/2020 v2022

EMODnet Chemistry aims to provide access to marine chemistry datasets and derived data products concerning eutrophication, acidity and contaminants. The importance of the selected substances and other parameters relates to the Marine Strategy Framework Directive (MSFD). This aggregated dataset contains all unrestricted EMODnet Chemistry data on potential hazardous substances, despite the fact that some data might not be related to pollution (e.g. collected by deep corer). Temperature, salinity and additional parameters are included when available. It covers the Norwegian Sea, Barents Sea, Greenland Sea and Icelandic Waters. Data were harmonised and validated by the 'Institute of Marine Research - Norwegian Marine Data Centre (NMD)' in Norway. The dataset contains water and sediment profiles. The temporal coverage is 1974–2011 for water measurements and 1974–2020 for sediment measurements. Regional datasets concerning contaminants are automatically harvested and the resulting collections are harmonised and validated using ODV Software and following a common methodology for all sea regions ( https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4). Parameter names are based on P01 vocabulary, which relates to BODC Parameter Usage Vocabulary and is available at: https://vocab.nerc.ac.uk/search_nvs/P01/. The harmonised dataset can be downloaded as as an ODV spreadsheet, which is composed of a metadata header followed by tab separated values. This spreadsheet can be imported into ODV Software for visualisation (more information can be found at: https://www.seadatanet.org/Software/ODV). In addition, the same dataset is offered also as a txt file in a long/vertical format, in which each P01 measurement is a record line. Additionally, there are a series of columns that split P01 terms into subcomponents (substance, CAS number, matrix...).This transposed format is more adapted to worksheet applications (e.g. LibreOffice Calc).

欧洲海洋观测与数据网络（EMODnet）化学分部（EMODnet Chemistry）旨在提供与富营养化、酸化及污染物相关的海洋化学数据集与衍生数据产品的访问渠道。所选物质及其他参数的重要性与《海洋战略框架指令（Marine Strategy Framework Directive，MSFD）》密切相关。本聚合数据集涵盖所有无使用限制的EMODnet Chemistry潜在有害物质相关数据，尽管其中部分数据可能与污染无关（例如由深海取样器采集的数据）。若有可用数据，还将包含温度、盐度及其他补充参数。数据集覆盖挪威海、巴伦支海、格陵兰海及冰岛海域。本数据集已由挪威海洋研究所-挪威海洋数据中心（Norwegian Marine Data Centre，NMD）完成统一化处理与验证工作，包含水体与沉积物剖面数据。水体测量数据的时间覆盖范围为1974年至2011年，沉积物测量数据的时间覆盖范围则为1974年至2020年。针对污染物的区域数据集将自动采集，所得数据集集合将遵循适用于所有海域的通用方法，并通过ODV软件完成统一化处理与验证工作（https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4）。参数名称基于P01词汇表（P01 vocabulary），该词汇表关联英国海洋学数据中心（British Oceanographic Data Centre，BODC）参数使用词汇表，其公开访问地址为：https://vocab.nerc.ac.uk/search_nvs/P01/。经统一化处理后的数据集可下载为ODV电子表格文件，该文件由元数据表头与制表符分隔值内容依次组成，此类电子表格可导入ODV软件进行可视化展示（更多信息可访问：https://www.seadatanet.org/Software/ODV）。此外，该数据集还提供长格式/垂直格式的TXT文件版本，其中每条P01测量数据均对应一条记录行。该文件还包含一系列列字段，可将P01术语拆分为多个子项（例如物质名称、化学文摘社（Chemical Abstracts Service，CAS）编号、基质类型等）。这种转置格式更适配电子表格应用程序（例如LibreOffice Calc）。
