Black Sea - Contaminants aggregated datasets 1974/2023 v2025

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 Black Sea. Data were harmonised and validated by the ‘National Institute for Marine Research and Development "Grigore Antipa" in Romania.
The dataset contains water, sediment and biota profiles. The temporal coverage is 1974–2023 for water measurements, 1990–2023 for sediment measurements and 2008–2019 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 旨在提供与富营养化、酸化及污染物相关的海洋化学数据集及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不受限制的EMODnet Chemistry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，还将包含温度、盐度及其他相关参数。数据集覆盖黑海海域。该数据集由罗马尼亚“格里戈雷·安蒂帕”海洋研究与发展国家研究所完成数据协调与验证工作。

本数据集涵盖水体、沉积物及生物群落剖面数据。水体测量数据的时间覆盖范围为1974年至2023年，沉积物测量数据为1990年至2023年，生物群落测量数据则为2008年至2019年。

针对污染物的区域数据集将自动采集，所得数据集集合将使用ODV软件(ODV Software)并遵循适用于所有海域的统一方法完成数据协调与验证（DOI：10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4）。参数名称基于P01词汇表，该词汇表关联BODC参数使用词汇表，可通过以下网址获取：https://vocab.nerc.ac.uk/search_nvs/P01/。

经协调后的数据集可下载为ODV电子表格格式，该格式由元数据表头后跟制表符分隔值组成。此类电子表格可导入ODV软件(ODV Software)以进行可视化操作（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，其中每条P01测量数据均为一条记录行。该文件还包含一系列列，用于将P01术语拆分为子组件（如物质名称、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（如LibreOffice Calc）。
