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. Whole Stream Metabolism was calculated using dissolved oxygen, discharge, stage, and temperature measured by sounds deployed in the field.

EML revision ID:
Dissolved Oxygen, Conductivity, and Temperature values were recorded in the field with 600 OMS YSI Sondes. Data was loaded and sondes were recalibrated every one or two weeks. Dissolved Oxygen value calibrations were tracked and corrected at the end of the season.
Data was organized and run by a program created in RStudio.
