How prehistoric water pit stops may have driven human evolution
Post by Matthew Robert Bennett, Bournemouth University and Mark O Cuthbert, Cardiff University Our ancient ancestors seem to have survived some pretty harsh arid spells in East Africa’s Rift Valley over five million years. Quite how they kept going has long been a mystery, given the lack of water to drink. Now, new research shows that they may have been able to survive on a small networks of springs. The …

Squeezed by gravity: how tides affect the groundwater under our feet
While we don’t tend to notice Earth and atmospheric tides, they do affect both the land and the world’s largest freshwater resource located underneath our feet: groundwater. This occupies the pores that exist in geological materials such as sand or soil, much like water in a kitchen sponge.

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 …
