Abstract:
Groundwater is the slow grandparent of the hydrologic system that most earth system models and analysis ignore or don’t really know how to talk to. Yet, groundwater affects a myriad of Earth systems and processes such as the atmosphere, oceans, volcanoes, earthquakes, weathering and petroleum migration. The study of groundwater systems within the broader Earth system is an exciting and emerging field and recent work suggests that globally, groundwater systems are often not well connected to other Earth systems such as the climate and oceans but hints at the possibility of strong local interactions at hotspots. Terrestrial groundwater and climate are only dynamically coupled on decadal timescales in a small fraction of the earth’s surface. Similarly, the fresh groundwater contribution to the global ocean is mostly insignificant except for specific locations.
