Global fossil groundwater resources—the grandkids like hanging out with the grandparents!!!
Post by Scott Jasechko, University of Calgary Groundwater is the world’s largest family of fresh and unfrozen water, and its members range from young to old. There are toddler groundwaters recharged more recently than the year ~1960. Our earlier research showed that these modern groundwaters make up only a small share of global groundwater stocks (Ref. 1 and Water Canada). But what of ancient ‘fossil’ groundwater—defined as groundwater that first …

The importance of groundwater for climate models
Contributed by Nir Krakauer [email protected] Does water fall if no one hears it? It does. Invisible water flows slowly under the ground, in soil and rock, downhill or from wet to dry areas.
