This $211,792 federal Project Grant awarded by the National Science Foundation (NSF) Geosciences program supports research to improve models of river chemistry and the global alkalinity cycle. The project, titled "BALANCING THE GLOBAL ALKALINITY CYCLE BY IMPROVING MODELS OF RIVER CHEMISTRY," is being conducted by William Marsh Rice University in Houston, Texas. The research aims to develop new analysis approaches to separate the effects of flow paths and flow rates on river water chemistry, leveraging time-series data to constrain coupled subsurface water transit and solute acquisition timescales. The work will also include engaging undergraduate students through an engineering design course, internships, and public outreach on local water quality issues. Additionally, the project will design a new, design-for-purpose autosampler to facilitate collecting time-series data. This research is intended to provide insights into the role of critical zone structure in the climate-weathering feedback and improve mixing models for trace element and isotopic proxies. The award period runs from January 1, 2025 through December 31, 2029.
