Water from 400AD in mystery ocean abyss

It's called the "shadow zone" and it lies around two kilometres below the surface in an ocean abyss where trapped water dates back to the fourth century. This ancient water, which is between 1000 and 2000 years old, dates back to when the ancient Germanic tribe the Goths instigated the end of the Western Roman Empire and the rise of Medieval Europe.

Lying in a 6000km by 2000km patch of the North Pacific Ocean between 1km and 2.5km below the surface, the shadow zone's reason for existence has remained a mystery until now.

...

"Abyssal ocean overturning shaped by sea floor distribution" explains that the zone has barely any vertical movement because factors prevent it from rising. The zone lies between rising currents caused by the rough topography and geothermal heat sources below 2.5km and the shallower wind driven currents closer to the surface.

"When this isolated shadow zone traps millennia old ocean water it also traps nutrients and carbon which have a direct impact on the capacity of the ocean to modify climate over centennial timescales," said the paper's fellow author Dr Fabien Roquet of Stockholm University.

I don’t know if there is “new” water on this planet, but there is definitely “recent” water as compared with old or ancient water. Current surface water or moisture in the soil evaporates into water vapor, and actually volcanoes release new water vapor, the water vapor coalesces into rain or snow and falls on earth or ocean. Or it melts and flows from earth surface into streams and rivers and flows to lakes and oceans. There we now have new water. Of course there is also the new water that sinks into the earth and becomes part of the water table where it mixes with older water or eventually flows into streams and rivers by which time it is also older water. Thus your well water may be well aged. So enjoy!

If I ever start selling this as bottled water, I’ll remember to put a really old date on it (well is down into the Marshall sandstone).

This picture shows ALL of Earth's water (liquid, ice, freshwater, and salt water) as a sphere. It would be about 860 miles in diameter (about the distance from Salt Lake City, Utah to Topeka, Kansas, USA). Credit: Illustration by Jack Cook, Woods Hole Oceanographic Institution; USGS.

Easy. All water is as old as the earth after the original making with the follow on of meteorites. So it’s all old.

You create new water every time you drive your car.

That’s a deceptive picture... we use land for living on by area, while water we use by volume. The only land we use is a very thin surface layer, much thinner than the oceans are deep, not all that rock and hot metal below that our mines can’t even reach. We’re not asbestos worms.
It would be more accurate to wad all of the surface we live on into a ball and compare it to fresh water... you’ll find a much more balanced look.
And why use a globe stripped of both fresh and salt water if the water they are referring to is only the fresh water? Just to make the fresh water look extra small by comparison, of course.

The label on the bottle tells you when it was “manufactured”....

[GingisK]

Same old carbon and oxygen from long ago.

“You create new water every time you drive your car.”

But the question remains, if it is so easy to create water, and that there doesn’t appear to be a saturation point, then why are we short?

I recall specifically being taught in 3rd grade Catholic school that BC = Before Christ” and AD = After Death” ...

I wondered for some time how time was marked during “Christ’s ~ 33 years on earth ... now I only worry about the 7 days between Christmas and New Year’s Day. ;-)

Instead of AD and BC
CE and BCE are used in exactly the same way as the traditional abbreviations AD and BC.

AD is short for Annus(sic) [actually, Anno] Domini,
Latin for year of the Lord.
BC is an abbreviation of Before Christ.
Because AD and BC hold religious (Christian) connotations, many prefer to use the more modern and neutral CE and BCE to indicate if a year is before or after year 1.

I know their intent is to separate Christ and God from yet another institution, in this case being the measurement of time.

LOL. Your parents should get your tuition for that semester reimbursed.
