The Lifeblood of a Planet

riverThe global hydrologic cycle provides connectivity among the aquatic, atmospheric, and terrestrial components of the Earth. The availability of water affects all life processes, and the need for high quality water is a societal concern linking human communities of every size around the globe.

Our research program reflects the complexity of the hydrologic cycle. We address the physical, chemical, and biological influences on the properties of water at multiple spatial scales in the atmosphere where it is directly linked to energy, climate, and weather; watersheds where the interplay between natural ecosystems and human activity affects water quantity and quality; and marine systems where it connects all land masses, mediates the exchange of heat and matter from the Earth's crust, and plays essential roles in global climate.
