Comparing Groundwater Sampling Methods for Denitrification Assessment: A Focus on N2 and Ar Measurements

The dataset comprises analysis results (major ions, N2, and Ar concentrations) from groundwater samples taken in the Lower Rhine Embayment (Germany) to assess the impact of sampling methods on N2, Ar, and excess-N2 concentrations.
The data is used in the manuscript \"Comparing Groundwater Sampling Methods for Denitrification Assessment: A Focus on N2 and Ar Measurements\" by Felix Fahrenbach and Thomas R. Rüde, which is currently undergoing review by Water Resources Research.

The libraries tidyverse, psych, car, rstatix, and PMCMRplus need to be installed to run the R scripts.
Running the Python scripts requires the following packages: numpy, pandas, scipy, statsmodels, and matplotlib.

本数据集涵盖采自德国下莱茵河洼地的地下水样品分析结果，包括主要离子、氮气（N2）与氩气（Ar）浓度数据，旨在评估采样方法对N2、Ar及过剩氮气（excess-N2）浓度的影响。
该数据集被应用于Felix Fahrenbach与Thomas R. Rüde合著的研究手稿《用于反硝化评估的地下水采样方法对比：聚焦N2与Ar测量（Comparing Groundwater Sampling Methods for Denitrification Assessment: A Focus on N2 and Ar Measurements）》，目前该手稿正由《Water Resources Research》期刊进行同行评审。
运行配套R脚本需预先安装tidyverse、psych、car、rstatix及PMCMRplus等R语言扩展包。
运行配套Python脚本则需安装以下Python扩展包：numpy、pandas、scipy、statsmodels及matplotlib。
