CLM - Bore water quality NSW

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nThis dataset contains the groundwater quality data for the NSW part of the Clarence-Moreton Basin. The data are sourced from the NSW state groundwater databases. The data were reorganized by aquifers based on the results of aquifer assignment. The overall quality of the chemistry data is highly variable. However, no quality check was conducted for this dataset from the point of view of geochemistry.\n\n## **Dataset History** \n\nThis dataset was compiled through the following process:\n\n\n\n1. Filter the data using the spatial extent of the Clarence-Moreton Basin;\n\n2. Aquifer assignment. Seven screen codes are used to indicate different bores in terms of their spatial relationship with a particular aquifer.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) CLM - Bore water quality NSW.

## **摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多源数据集衍生得到。本元数据声明中的「谱系（Lineage）」字段已列明其来源数据集，而该衍生数据集的生成流程详见元数据声明中的「历史（History）」字段。

本数据集涵盖克拉伦斯-莫顿盆地（Clarence-Moreton Basin）新南威尔士州（NSW）辖区内的地下水水质数据，数据源自新南威尔士州地下水数据库。研究人员依据含水层赋值结果，按含水层类型对数据进行了重组。该化学数据的整体质量参差不齐，但尚未从地球化学视角对本数据集开展质量核查。

## **数据集编制历史**
本数据集通过以下流程编制完成：
1. 基于克拉伦斯-莫顿盆地的空间范围对数据进行筛选；
2. 含水层赋值。本次采用7种筛管编码，依据钻孔与特定含水层的空间关联关系区分不同钻孔。
