We know that in phreatic loops, moving fresh water can reach down 100 metres or so below sea level
but how deep can fresh water actually go?

Pitlamp said:Some of the inland blue holes in the Bahamas are extremely deep, with fresh water in them.
Pitlamp said:Water can even flow "uphill" from its inflow point, as in that wierd spring on Argostoli.
Pitlamp said:Aren't there supposed to be some springs where the water is of non meteoric origin (i.e. with water emerging which was produced by chemical reactions in volcanic rocks all the way down in hell?)
Depends where its coming from and where its going, heads of pressure, relative densitives, Tempretures, etc. etc.whitelackington said:We know that in phreatic loops, moving fresh water can reach down 100 metres or so below sea level

Give me a reference, I'll work on the speliogenesis.Pitlamp said:water emerging which was produced by chemical reactions in volcanic rocks all the way down in hell

Pitlamp said:(Graham - I'm pretty sure that some of the blue holes have fresh water very deep - again a bit busy at the mo to go looking things up - but wasn't there a Cave Science / Cave & Karst Science themed edition on the blue holes? You might find some info there.)
Ouan said:A fresh water vauclusian resurgence near Krabi in southern Thailand, located 5 km from the coast, has been dived to -240m.
The resurgence is about 10 m above sea level i.e. fresh water is found 230 m below sea level.
