This dataset contains Carbon, Nitrogen, and Deuterium isotope values for Fine Particulate Organic Matter, Dissolved Organic Matter, Dissolved Inorganic Carbon, Dissolved Nitrate, and water for 4 watersheds in Utah. Samples were collected in September and November of 2014 and November and December of 2015. Eight sites in the Provo River, Logan River, and Red Butte Creek and 9 sites on the Jordan River were sampled.

Additional Metadata

Name Value
Observed Variables carbon isotope value DOM, nitrogen isotope value FPOM, Hydrogen isotope value DOM, Hydrogen isotope value FPOM, Dissolved inorganic carbon value, Nitrate isotope value Nitrogen, Nitrate isotope value oxygen, Water isotope value Hydrogen, Water isotope value Oxygen
Variable Description Various isotope values of carbon, nitrogen, and hydrogen for riverine organic matter. Carbon and nitrogen isotopes samples were sent to UC Davis Stable Isotope Facility. Deuterium of organic matter was sent to the Colorado Plateau Stable Isotope Lab at Northern Arizona University.
Data Collection Method DOM, nitrate, DIC and FPOM were collected with a 0.7 um glass fiber filter in a drill pump. Water for isotopes was a grab sample
Data Processing Method DOM and FPOM intended for CN analysis were acidifed and dehydrated. DOM and FPOM intended for H analysis was not acidified and dehydrated. Nitrate was frozen and sent to UC Davis Stable Isotope Facility where it was analyzed using the denitrifier method. DIC was acidified in an exetainer with phosphoric acid and sent to UC Davis. Hydrogen and Oxygen isotopes of water were analyzed on an EA at Utah State University Stable Isotope Laboratory.
