Panama Canal Authority Water Quality Monitoring

Since 2003, the Panama Canal Authority (Autoridad del Canal de Panamá - ACP), has operated a water quality monitoring program throughout the Panama Canal Watershed (see Figure 1 and Table 1 for location of stations). The ACP samples water quality once per month. The ACP published the results of this monitoring program in yearly reports that are available on-line here: https://micanaldepanama.com/nosotros/cuenca-hidrografica/. These reports are available in PDF format only. The quality of the PDF’s varies year-by-year. The reports for some years are particularly poor and, as a result, the process of converting the documents to text was difficult. Every effort was made to ensure the accuracy of the scans, but a small number of errors are likely. STRI has digitized the contents of these reports and converted them into numeric databases. Each variable is stored in its own separate table. Table 2 lists all available files and their definitions. Unfortunately, the quality of the 2011 report was very poor and it was not possible to do automatic character conversion. The data for this report are not yet available in database format.

自2003年起，巴拿马运河管理局（Autoridad del Canal de Panamá，缩写ACP）便在巴拿马运河流域内持续开展水质监测项目（监测站点位置详见图1与表1）。该管理局每月进行一次水质采样，监测结果以年度报告形式发布，相关报告仅可通过以下在线链接获取：https://micanaldepanama.com/nosotros/cuenca-hidrografica/。所有报告仅以PDF格式提供，不同年份的PDF文件质量参差不齐，部分年份的报告质量尤为欠佳，致使文档文本转换工作难度大幅提升。尽管已尽最大努力保障扫描转换的准确性，但仍可能存在少量误差。史密森尼热带研究所（STRI）已将这些报告的内容数字化，并转换为数值数据库，每个监测变量均单独存储于一张独立数据表中。表2列出了所有可用文件及其对应说明。遗憾的是，2011年的报告质量极差，无法进行自动字符转换，该年度报告对应的数据集暂未以数据库格式开放。历史数据集可通过以下链接获取：https://smithsonian.figshare.com/articles/dataset/Panama_Canal_Authority_Water_Quality_Monitoring/11793768
