Arctic Great Rivers Observatory Data 2003-2019 Fixed Data Package

These data are associated with a manuscript under consideration for publication, and are therefore provided as a fixed data package. The continually updated ArcticGRO data package can be found at the Arctic Data Center doi:10.18739/A2XW47X7D In summer 2003, the Arctic Great Rivers Observatory (ArcticGRO) began to collect the first methodologically-consistent series of river water chemistry samples at downstream sites on the six largest rivers draining to the Arctic Ocean: the Ob’, Yenisey, Lena, and Kolyma in Russia, and the Yukon and Mackenzie in North America. These measurements have continued largely uninterrupted to this day. This data package is associated with a publication that presents the first comprehensive time series analysis of this nearly 20-year dataset. Details on sample collection and analyses are provided in the “methods” section, below.

本数据集关联一篇待发表的学术稿件，因此以固定数据包形式提供。持续更新的ArcticGRO数据包可在北极数据中心获取，其DOI编号为10.18739/A2XW47X7D。2003年夏季，北极大河观测站（Arctic Great Rivers Observatory，缩写ArcticGRO）启动采样工作，首次在注入北冰洋的六大河流的下游站点采集方法统一的系列河水化学样品：俄罗斯境内的鄂毕河、叶尼塞河、勒拿河与科雷马河，以及北美洲的育空河与马更些河。该监测工作迄今基本未中断，持续开展至今。本数据包关联一篇学术论文，该论文首次对这份近20年的数据集开展了全面的时间序列分析。样品采集与分析的具体细节详见下文的「方法」章节。
