Influence of ecosystem water and nutrient demands on riverine solute exports
Water is a driver of Critical Zone structure and function, converting rock to soil, liberating vital nutrients locked in minerals and sustaining primary productivity. Upland ecosystems host the inception of river chemistry and dictate the initial chemical quality of water resources. The process begins with dilute rainfall infiltrating through shallow, CO2-rich soils, draining deeper into the subsurface, promoting a cascade of coupled primary mineral dissolution and secondary mineral formation reactions. Vegetation requires, and even promotes these water-rock reactions to access vital nutrients bound in mineral phases. What is not scavenged by secondary minerals or taken up by ecosystems remains in the water as it drains through the subsurface to become the solute composition of discharge to streams and rivers.
Our capacity to understand these interactions through the lens of hydrochemical records is rooted into our ability to quantitatively describe reactive solute transport through the Critical Zone. We welcome submissions related to the development of analytical or modelling tools, based on laboratory or field approaches, aiming at improving our understanding of the impact of ecosystems on water partitioning and routing of nutrients in catchments.

After the abstracts collection is published (eLTER Science Conference 2025 Proceedings), ACA disseminates, indexes and archives all abstracts. Each abstract is registered at Crossref and assigned with its own DOI. Further, the authors are welcome to add video recordings of their conference talks or graphic files of poster presentations, which shall be visualised on the abstract’s webpage. Learn more here.
