Baltic Sea - Contaminants aggregated datasets 1972/2021 v2024

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 Baltic Sea. Data were harmonised and validated by the ‘Swedish Meteorological and Hydrological Institute (SMHI)’ in Sweden.
The dataset contains water, sediment and biota profiles. The temporal coverage is 1987–2021 for water measurements, 1974–2021 for sediment measurements and 1972-2021 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).

欧洲海洋观测与数据网络化学分部（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权限。所选物质及其他相关参数的选取标准均符合海洋战略框架指令（Marine Strategy Framework Directive，MSFD）的要求。本聚合数据集涵盖了所有无使用限制的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（例如通过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。数据集覆盖波罗的海海域。相关数据已由瑞典的瑞典气象与水文研究所（Swedish Meteorological and Hydrological Institute，简称SMHI）完成统一标准化处理与验证工作。本数据集包含水体、沉积物及生物群落的相关剖面数据。时间覆盖范围方面，水体测量数据为1987年至2021年，沉积物测量数据为1974年至2021年，生物群落测量数据为1972年至2021年。针对污染物的区域数据集将自动采集，所得数据集集合将通过ODV软件（ODV Software）完成统一标准化处理与验证，并遵循适用于所有海域的统一方法规范（详见 https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4）。参数名称基于P01词汇表（P01 vocabulary），该词汇表与BODC参数使用词汇表（BODC Parameter Usage Vocabulary）相关联，其公开网址为：https://vocab.nerc.ac.uk/search_nvs/P01/。经标准化处理后的数据集可下载为ODV电子表格格式，该格式由元数据头部与制表符分隔值内容两部分组成。此类电子表格可导入ODV软件以进行可视化处理（更多相关信息可参阅：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测量数据均为一条记录行。该格式还包含多列字段，可将P01术语拆解为多个子项（如物质名称、CAS编号、基质类型等）。此种转置格式更适配电子表格软件（如LibreOffice Calc）的使用需求。
