Drought-induced secondary carbonate formation restricts lateral carbon transport

Nature Geoscience (2025)Cite this article

Subjects

Over a prolonged period of hydrologic drought, the major ion chemistry of a North American river dramatically shifted, revealing reduced lateral carbon transport due to secondary carbonate formation. These observations expose a natural limit to the inorganic carbon carrying capacity of rivers.
