Supporting Data for journal article entitled "Hydrologic and Geological Controls on Chemical Weathering and Associated Carbon Sink in a Silicate-dominated River Basin"

This is the supporting data for journal article entitled "Hydrologic and Geological Controls on Chemical Weathering and Associated Carbon Sink in a Silicate-dominated River Basin". In this study, we aim to investigate the chemical weathering rate and weathering-induced carbon sink in the East River basin (ERB) by employing a forward model method to analyze river water chemistry. Water samples were collected during five fieldwork campaigns from December 2018 to October 2019, including three in the wet season and two in the dry season. In total, 43 sampling sites widely distributed across the ERB were visited during each campaign.This dataset includes the results from water chemistry analyses conducted at these sites.
