Have you ever wondered if groundwater is connected to climate?

‘Groundwater-surface water interactions’ has become standard hydrologic lexicon and a perennial favorite session title at various conferences… but how often do you hear the phrase ‘groundwater-climate interactions’?

Celestial groundwater – the subsurface plumbing for extraterrestrial life support

Have you ever taken a walk on the beach during a lowering (ebbing) tide and see mini-rivers grow and create beautiful drainage patterns before your eyes? These short-lived groundwater seepage features are tiny (and fast) analogs of how groundwater has shaped some parts of Mars! It appears that groundwater loosening sediments can lead to all sorts of scales of erosion on both Earth and Mars.

Of Karst! – short episodes about karst

We often associate groundwater with large water storage and very slow water movement, for instance compared to rivers. But is it possible that groundwater flow can be as quick as stream flow? Of karst, it is possible!

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 …
