JGR-Oceans：Forward and Reverse Weathering Drive Sedimentary Porewater Carbon Cycling Across Contrasting Diagenetic Regimes in a Large River Estuary

Yuanqing Chen1,2, Christian März2, Zhe Zhou1, Shouye Yang1, and Zijun Wu11State Key Laboratory of Marine Geology, Tongji University, Shanghai, China, 2Institute for Geosciences, University of Bonn, Bonn, GermanyAbstract：Porewater dissolved inorganic carbon (DIC) cycling plays a central role in marine carbon budgets, yet its regulation by forward and reverse weathering remains poorly constrained on large-river-dominated continental shelves. To address this gap, we integrated porewater geochemistr
