North East Atlantic Ocean - Contaminants aggregated datasets 1966/2021 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 Northeast Atlantic Ocean (40W). Data were harmonised and validated by the '‘IFREMER / IDM / SISMER - Scientific Information Systems for the SEA’ in France. The dataset contains water (profiles), sediment (profiles and timeseries) and biota (profiles and timeseries). The temporal coverage is 1974–2018 for water measurements, 1966–2014 for sediment measurements and 1979–2021 for biota 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).

EMODnet Chemistry旨在提供海洋化学数据集及衍生数据产品的访问途径，内容涉及富营养化、酸化与污染物。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）相关。该聚合数据集包含EMODnet Chemistry所有非限制性的潜在有害物质数据，尽管部分数据可能与污染无关（例如由深海岩心取样器采集的数据）。若有可用数据，则包含温度、盐度及其他附加参数。其覆盖范围为东北大西洋（西经40度）。数据由法国的“IFREMER / IDM / SISMER - 海洋科学信息系统”（Scientific Information Systems for the SEA）进行协调与验证。该数据集包含水体（剖面数据）、沉积物（剖面及时间序列数据）与生物群（剖面及时间序列数据）相关记录。时间覆盖范围方面，水体测量数据为1974–2018年，沉积物测量数据为1966–2014年，生物群测量数据为1979–2021年。与污染物相关的区域数据集会被自动采集，所得集合通过ODV软件及适用于所有海域的通用方法进行协调与验证（参考文献：https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4）。参数名称基于P01词汇表，该词汇表与BODC参数使用词汇表相关，可通过以下链接获取：https://vocab.nerc.ac.uk/search_nvs/P01/。协调后的数据集可下载为ODV表格形式，该表格由元数据头及后续的制表符分隔值组成。此表格可导入ODV软件进行可视化（更多信息见：https://www.seadatanet.org/Software/ODV）。此外，同一数据集还提供长/垂直格式的txt文件版本，其中每个P01测量值对应一条记录行。同时，该格式包含一系列列，将P01术语拆分为子组件（物质、CAS编号、基质等）。这种转置格式更适用于电子表格应用（例如LibreOffice Calc）。
