Dataset for: Arctic plants can take up inorganic nitrogen year-round

This dataset contains the data from a year-round 15N pulse-labelling in a low-Arctic tundra done monthly over a full year. The experiment was conducted in Northern Sweden at two locations, one close to Abisko and another close to Vassijaure. The dataset contains data from the isotopic labelling and from environmental information gathered.The labelling data has been cleaned and contains basic information surrounding the sampling times, soil properties, plant and soil isotopic information, and soil inorganic N content (clean_data).The environmental information is from sensors in Abisko and Vassijaure, and snow depth is measured at the sites (raw_data). For the associated code, see the github repository: https://github.com/the-esherman/Project_I_15N_seasonality.本数据集包含在低北极苔原（low-Arctic tundra）开展的全年月度15N脉冲标记（15N pulse-labelling）实验的全部数据，实验以月度为间隔开展，覆盖完整一整年。本实验实施于瑞典北部两个采样点位，一处紧邻阿比斯科（Abisko），另一处临近瓦西约雷（Vassijaure）。 数据集涵盖同位素标记相关实测数据与采集得到的环境监测信息。其中标记数据集（clean_data）已完成清洗预处理，包含采样时序、土壤理化性质、植物与土壤同位素组分信息以及土壤无机氮含量等基础关联信息。环境数据集（raw_data）来源于阿比斯科与瓦西约雷点位的原位传感器监测数据，同时包含各研究点位的积雪深度观测结果。 相关配套代码可通过以下github仓库获取：https://github.com/the-esherman/Project_I_15N_seasonality。
