Canadian Arctic Archipelago Rivers Program: Major Ion and Inorganic Carbon Data 2016-2019

This data set describes the Dissolved Inorganic Carbon (DIC), Total Alkalinity (TA), and dissolved Major and Minor Ion (Chloride, Sulphate, Calcium, Magnesium, Sodium, Potassium, Strontium, Barium) data collected from 53 rivers, lakes, and glaciers throughout the Canadian Arctic Archipelago (CAA) and Hudson Bay as part of the Canadian Arctic Archipelago Rivers Program (CAA-RP; 2016 – 2019); ArcticNet / Amundsen Science biogeochemical surveys (2017-2019); the Canada 150 C3 Expedition (2017); and the BaySys project (2018). Water samples were collected according to methods developed by the Arctic Great Rivers Observatory (http://www.arcticgreatrivers.org/), described in detail in Brown et al., 2020. Water collected for the determination of dissolved major ion concentrations were filtered through 0.22 μm Sterivex cartridges (Millipore) into triply rinsed HDPE sampling bottles and stored in the dark at room temperature until they could be transferred to a fridge (4°C) until analyses. DIC and TA samples were filtered directly into glass sample bottles using a 0.45 μm cartridge installed in-line with a peristaltic pump. Analytical methods are described in the accompanying metadata file. The water temperature and conductivity data at the time of sampling and the related metadata are archived at doi:10.1594/PANGAEA.945702 .
