Birth of a New African Ocean
Khemisty writes "Formation of an ocean is a rare event, one no scientist has ever witnessed. Yet this geophysical nativity is unfolding today in one of the hottest and most inhospitable corners of the globe. Africa is splitting apart at the seams. From the southern tip of the Red Sea southward through Eritrea, Ethiopia, Kenya, Tanzania, and Mozambique, the continent is coming unstitched along a zone called the East African Rift." This stretching of the earth's crust has been going on for 20 million years, and within another 10 million the Red Sea will have broken through to create a new sea.
blamemoses.
The World Wide Web is dying. Soon, we shall have only the Internet.
Bet there would be one very impressive waterfall when the Red Sea finally breaks through.
This ain't rocket surgery.
That 10 million years from now, the split will be complete. Slashdot will report this, and one /.er will complain, "It's a dupe! This story appeared 10 million years ago! What's up with the cyborg editors?"

... without relief maps.
I don't want to read some art's grads long winded verbose description of something that can be shown to me in 2 diagrams.
Before long, someone will blame this on GlobalWarming.
Mention of this split WILL show up in someone's eco-speech.
Well there goes property values...

There's another ocean forming in the Gulf of California. It's the same story with a rift underneath. The rift actually runs up to Albuquerque in New Mexico.

parts of the area are over 100 meters below sea level. Low hills to the east are all that stops the Red Sea from encroaching.
Let's get to work and develop some shoreline real estate!

There are already a few pirates in the vicinity.
Do you really need to give the trolls encouragement to post yet another Goatse link?
Haha, this is news to Slashdot?
The African Rift Valley has been taught to first year geology students since plate tectonics were discovered decades ago.

So actually *every scientist* has witnessed this event...

Well, that's cold comfort for the inhabitants who are unable to sustain crops because of not having a water supply nearby.

I hope they post this shit to youtube; that's gonna be really cool. Pressing reload already.
It's in this part of eastern Africa, adjacent to the junction of the Red Sea and Gulf of Aden in Ethiopia and Eritrea, and is known as the Afar Depression. All this black stuff is Erte Ale, a volcano that is almost continuously erupting. You can see the fresh black lava flows that historically oozed down the sides, and if you zoom in, you can see the red glow of the lava lake. The salt pan areas mentioned in the article are to the north (Danakil Depression), and are well below sea level (the Wikipedia page on the former settlement of Dallol notes that Dallol is 50m above sea level, but that's the settlement site, not the lake/salt pan, which is lower). There are vast areas of stretched and faulted crust to the southeast (the cliffs are the fault scarps), and Lake Assal, another salt lake 153 metres below sea level.
This area is more impressive if you fly over it in Google Earth rather than Google Maps. Practically every cone-shaped peak you see in this area is a volcano that has been recently or not so recently active, and to the south you can clearly see the flanks of the East African Rift and the series of lakes that occupy the rift valley as far south as Kenya, Tanzania and Mozambique, interspersed with volcanoes all along the way. This is an awesome part of the world for geology.
For more information, you can try the Afar Rift Home Page for the Afar Rift Project.
It starts small. It WILL be an ocean. AFTER it goes through the sea stage. Right now it's still just a "rift".
When thinking about geologic processes, it's very important to consider the time dimension.
... melting ice cap water.
and even more important we find out that pulling in water from the salty oceans across alot of land makes teh water much more drinkable.
I thought it was well-known in scientific circles that the East African Rift Valley was going to eventually result in the formation of this. TFA seems to be really describing the interesting geological processes that can be seen in the rift valley, not breaking the news that it exists and that it will eventually turn into an ocean.
Free Ocean!!!
I must agree with the guys who have said this is not news... I studied this, and several other such geological events in Geography classes at the U.W. a decade ago... It was old info then...
i.e. The bottom of Hudson Bay bobs up and down like a boat floating in water. Like a metronome it rises too far and that whole area becomes a high mountain plain as it pushes the water out and then it falls too far becoming a "bay" that should be called a "sea" at least... It takes millions of years for each cycle and it rises/falls slightly less each time, so in about 100 billion years it might come to rest... maybe about the same time the Pacific Ocean becomes just a river between the continents we now call North America and Asia...
The frustrated weaponeer in me thinks "Hey! That's how we deal with ocean levels rising! Find some basins and nuke holes between them and oceans!"
Heh.

This isn't news, unless you state it has created a new ocean today. Which if it has, we better put our heads between our legs and kiss our butts goodbye.
This is interesting, sure, but how is this news? If it has been going on for the last 10 million years, why are we talking about it now? Was this just discovered? Perhaps I didnt RTFA well enough, but I'm missing whats happened.
We must create regulations that stem this awful tide which threatens ancient ways and will likely cause hardship on families. When Bono speaks to this ocean, I want the ocean to listen and offer to help.
...for a long time.
If pointung out some problems with parent post gets labelled as "troll"...I'm not sure if saying that people wear blinkers on their eyes regarding the issues is enough, seems like they want it to stay that way.

So that's what they mean when they say "travellers from Afar". I always suspected that was somewhere in Africa.
Then pray tell, just what continent does the african rift valley lie in? That's the most prominent rift valley that I know of...

This is the area in Afrca where "Lara Croft Tomb Raider: The Cradle of Life" is set.
He's the one who said we needed change!
It amazes me that in the face of such collossal changes in science (like from flat earth, to round) that we're still reluctant to explore the possibility that maybe the earth hasn't really been the same size for millions of years.
Troll my ass, you TWIT! Is it true or not?

"in one of the hottest and most inhospitable corners of the globe" According to American Media I thought that was in reference to countries in the Middle East, oh, I mean N. Korea, actually according to US Media anywhere that is not geographically located in N. America or Western Europe.
FGS! What a dumb story. Light relief at best.
Of course the continents will change in the next 10 million years! Unless Armageddon comes first.

Really, I think I heard about this 20 yrs ago. Since it's been happening over millions of years, and will take millions of years. I am not sure I accept either of the stated premises.
1. This is NOT the birth of a new ocean, unless the crack finally spread all the way to the ocean so as to unleash a rush of water that drowns the ensuing valley and literally creates an instant sea that was not there yesterday morning - than this is NOT a birth.
2. As it's happening over 20 million years and we're in the middle part of that. I do not think that qualifies as observing the birth. That'dbe like claiming to have observed grass growing. Sure it's longer over a few days and now I need to mow. But who has literally watched a single blade of grass grow and distinguished it's growth over a few hours. Not many of us...
At the inception of IQ tests, it was true, but only if we don't consider that those of sub-par IQ have a lower life expectancy, and such the actual population is going to average higher.
People with lower IQs probably don't have a significantly lower life expectancy, and they sure reproduce a lot more (providing both the nature (barring any lucky genetic quirks/throwbacks) and nurture to raise unintelligent children)...but these are just my observations.

I can hardly wait to see this!!
Ok so I got some time b4 I need to break out the popcorn for the show.
Considering I have an IS degree and not a geology degree and this is the first time I've heard of it, yes it is news. And I find it worthy of news for nerds, as I am a nerd and find this fascinating.
I have a son interested in geology as well, he probably hasn't heard of this. Perhaps he'll get a head start on his degree and start looking things up now.

Good thing no one asked me, huh?

So it's not really going to happen "today," now is it?
if global warming is actually an abnormal event, not a cycle that occurs over time, which if you look at environmental history from old cultures you see constant back and forth fluctuation between several climates in these areas, such as the
Roman Empire to the Middle Ages to modern day. the Earth may be simply adapting to the "rising oceans", which have risen and fallen the exact same way they are now over time. don't you love how science kicks itself in the butt so often?
