Description:
This data set describes the stable water isotope (δ18O-H2O, δ2H-H2O), Dissolved Organic Carbon (DOC), and Nutrient (Nitrate + Nitrite, Phosphate, Silicate) 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 stable water isotope, DOC, and Nutrient analyses was filtered through 0.22 μm Sterivex cartridges (Millipore) into triply rinsed glass (isotopes) or HDPE (Nutrients, DOC) vials; HDPE vials were acid cleaned prior to use. Samples for the determination of DOC and Nutrients were frozen until analyses, whereas stable isotope samples were stored in the dark at room temperature or refrigerated until analyses. Analytical methods are described in the accompanying metadata file. Where indicated, water Temperature and Conductivity at the time of sampling were determined as described in the dataset metadata file.
