Nutrient and tracer amounts for Tracer Additions for Spiraling Curve Characterization studies on arctic streams near Toolik Field Station, Alaska 2010 -2012.

The Changing Seasonality of Arctic Stream Systems (CSASN) was active from 2010 to 2012. The CSASN goal was to quantify the relative influences of through flow, lateral inputs, and hyporheic regeneration on the seasonal fluxes C, N, and P in an arctic river network, and to determine how these influences might shift under seasonal conditions that are likely to be substantially different in the future. There were a number of tracer addition for spiraling curve characterization (TASCC) and Plateau nutrient additions at each sampling location. The data in this file contains nutrient concentrations from each sampling event during each TASCC and Plateau addition during the CSASN project. This file contains all the information about each nutrient addition during the entire project.
