The nsink package estimates cumulative nitrogen (N) removal along a specified flow path and is based on methodologies outlined in Kellogg et al. (2010). For a user-specified watershed (i.e., hydrologic unit code (HUC)), nsink downloads all required datasets from public datasets in the United States, prepares data for use, summarizes N removal along a flow path and creates several static maps. The results of an nsink analysis may be exported to standard geospatial files for use in other applications.
nsink软件包可估算沿指定水流路径的累积氮（N）去除量，其基于Kellogg等人（2010年）概述的方法。对于用户指定的流域（即水文单元代码（HUC）），nsink从美国的公共数据集中下载所有所需数据集，准备供使用的数据，汇总沿水流路径的氮去除量，并创建几张静态地图。nsink分析的结果可导出到标准地理空间文件中，以供其他应用程序使用。
