It seems crucial to contemplate how Earth's systems adapt to climate and environmental change as well as how these processes provide feedback to each other. Laboratory of Environmetal Geochemistry in Ewha Womans University have been focusing on global water cycle research including stable water isotopes and studying the global material cycle using various stable isotopes. We aim to identify environmental geochemical proxies that respond to rapid climate and environmental changes using chemical analysis and numerical aid in temperate and  polar regions.
