Short summary
Rivers export the products of continental weathering to the oceans. It is important to accurately constrain these fluxes to better understand global biogeochemical cycles. The riverine export of major cation species in particular contributes to regulate the long-term carbon cycle. In this work we quantify some additional fluxes to the ocean that may occur when solid sediments react with seawater in estuaries. These fluxes have been only poorly constrained so far.
