Yael Kiro

Congratulations to Zuckerman Faculty Scholar Yael Kiro, TITLE at Weizmann Institute of Science’s Department of Earth and Planetary Sciences, on the publication of Alkalinity and carbon fluxes from coastal aquifers to the ocean via submarine groundwater discharge, in Communications Earth & Environment.. Dr. Kiro explores the history of Earth’s systems by analyzing deep-sea sediments and saline environments. Her research reconstructs past hydrological cycles to understand long-term climate variability, providing critical context for how modern climate change may influence aridity and water stability in the Middle East.

Abstract: 
The coastal ocean links land and sea through rivers and submarine groundwater discharge, which contribute to the coastal carbon budget. Groundwater discharge, including fresh groundwater and recirculated seawater, remains poorly constrained globally. Here, we compile a global dataset of coastal groundwater chemistry and estimate fluxes of dissolved inorganic carbon and total alkalinity. Using conceptual reaction models, we analyze the alkalinity-carbon relationship to identify dominant processes.
