The Kuparuk River has been the central research location on the impact of added phosphorus to arctic streams. Additions of phosphorus occred since 1983. Today, 4 specific reaches show certain characteristics based on the years that they recieved fertilization. Whole Stream Metabolism is a way to quantify primary production of this stream system. Calculations were done using dissolved oxygen, discharge, stage, light and temperature measured by sondes and other equipment strategically deployed in the field at locations to quantify each of the unique stream reaches.
Data set ID:
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.
DO values were adjusted based on expected DO concentrations and checks with a Pro ODO.
Methods follow typical methods in whole stream metabolism. Bott, T. L. Primary Productivity and Community Respiration. Chapter 28 in SR Hauer GA Lamberti (Eds.), Methods in Stream Ecology, 2nd edition. Academic Press, Boston.
