Abstract

STUDY: High-elevation mountain regions, central to global freshwater supply, are experiencing more rapid warming than low-elevation locations. High-elevation streams are therefore potentially critical indicators for earth system and water chemistry response to warming.

LOCATION: Hydroclimatic and biogeochemical data were collected from Coal Creek, Colorado, in the central Rocky Mountains at elevations of 2700 to 3700 m, where air temperatures have increased by about 2 °C since 1980.

STREAM CHEMISTRY: Water chemistry was analyzed every other day from 2016 to 2019 to examine stream chemistry response to climate variability in a high-elevation watershed. Water chemistry data indicate distinct responses of different solutes to inter-annual hydroclimatic variations. Concentrations of solutes from rock weathering are stable inter-annually. Solutes that are active in soils, including dissolved organic carbon, vary dramatically, with double to triple peak concentrations occurring during snowmelt and in warm years.

The dataset contains discharge, water temperature, and stream chemistry data for 2016–2019. Stream chemistry includes dissolved organic and inorganic carbon, chloride, nutrients, and cations.

FUNDING AND PROJECT CONTEXT: Data collection efforts were carried out in conjunction with the DOE-funded Advancing a Watershed Hydro-Biogeochemical Theory: Linking Water Travel Time and Reaction Rates Under Changing Climate project and Watershed Function SFA.
