[...] Mysterious 'Dark River' may flow for 1,000 km underneath Greenland

Thursday, November 19th 2020, 7:00 am - Models suggest that melting water from the centre of Greenland’s ice sheet could flow through a subglacial valley and exit into the ocean along the northern coast of the country. 

A study published in The Cryosphere considers how the canyons, trenches, and valleys within and underneath Greenland’s glaciers formed and what they could look like. The researchers state that this study is a thought experiment to speculate what could be underneath Greenland and suggest that there could be a river, nicknamed the ‘Dark River’, inconspicuously flowing for more than 1,000 kilometres from the deep interior of the massive continental glacier.

Ice-penetrating radar surveys and models of Greenland’s bedrock indicate that there could be a long valley, but the researchers are uncertain if it is continuous or broken into segments. To explore what would happen if deep parts of the ice sheet’s centre began to melt more quickly, they created simulations for valleys that were both continuous and segmented.

The models showed that an open valley would stretch over 1,000 kilometres from the interior out to the Petermann Fjord on Greenland’s northern coast. The valley is described as being “relatively flat” with elevations that range from 250 to 500 metres below sea level. “[The valley] follows a path near the interior ice divide that roughly intersects the east and west basal hydrological basins,” the researchers say in a press release. [...]

 

[...] “The results are consistent with a long subglacial river,” Chambers says, “but considerable uncertainty remains. For example, we don’t know how much water, if any, is available to flow along the valley, and if it does indeed exit at Petermann Fjord or is refrozen, or escapes the valley, along the way,” said Christopher Chambers, a scientist at Hokkaido University and one of the study’s authors.

This river supposedly runs from deep within Greenland linking Petermans glacier in the north. And, it is rather from where it starts to flow that i wanted to show here. There seems to be a clear coincidence happening with two different types of imagery:

The Garden of Eden is the biblical earthly paradise created by God to be inhabited by his first human creation - Adam and Eve. Some claim that the name “Eden” derives from the Akkadian term edinu, which means ‘plain’.

...and the reason this is in a new thread and not one of your previous 1,567 useless "Greenland is Atlantis thread" is?

And please don't  give us your typical "this isn't about Atlantis" ****, because we all know it is.

...and you wonder why people call you a pathological liar...

At least Aurora Borealis or the northern lights do look like the Cherubim and their swords (the guards of Paradise), being connected to storm winds bright clouds and lightnings... do you not agree?

I am glad you brought it up, because it is just more food for thought:

Quote

The researchers were looking for evidence of the typical bulldozer-like erosion, expecting to find little more than bedrock under the ice sheet. Bierman was looking specifically for a chemical element that forms when cosmic rays hit the Earth’s surface. Since Greenland had been covered by ice for significant portions of the past few million years, Bierman didn’t expect to find much of this element. He said, “We thought that the ice sheet had been erosive enough to remove any material that predated the ice on Greenland.” Instead, he and his team were surprised to find plenty of it in the core samples. “We realized that in fact there was preservation of material from a long time ago,” Bierman said. That meant the massive ice sheet didn’t bulldoze the tundra off Greenland’s surface, but simply froze it in place. How does a thick, moving sheet of ice leave an ancient landscape intact?

There is tundra in Greenland but that is not all, far from it, because according to my dear friend Eske Willerslev:

Fossil DNA Proves Greenland Once Had Lush Forests; Ice Sheet Is Surprisingly Stable

 
July 5, 2007
 
University of Copenhagen
 
Ancient Greenland was green. New Danish research has shown that it was covered in conifer forest and had a relatively mild climate. The research is painting a picture which is overturning all previous assumptions about biological life and the climate in Greenland. The findings also show evidence of ice in Greenland during the Eemian interglacial period 125,000 years ago, which indicates that although we are now confronted with global warming, the whole ice sheet will probably not melt and bring about the tremendous sea-level rises which have been the subject of so much discussion.

Most people would take that as a (not very subtle) hint. 

Maybe by now everyone recognizes your game — when you /do/ get a response, it will demonstrate to you (again) your deliberate ignorance and inability to make a cogent point, to which you’ll start to whine and throw around conspiracies about how the mods and other posters are ganging up against you, and you’ll make a whole production number out of how you’re leaving and never, ever coming back, only to show up again, throw around a few lies and start the whole embarrassing predicament again. 

But, yeah: you poke that bear.

Hahaha!!

Meaning: this find is about something more than 20 times as old as Plato's Atlantis.

So you are saying that Atlantis could not have existed in Greenland because they found DNA half a million years old?

Greenland was once ice free

Using data from a 3053-meter-long core of ice and bedrock collected from the center of the island in 1993, Schaefer’s team has found valuable clues to what the period held. In particular, the 1.55 meters of bedrock at the core’s base revealed much about the island’s history of glaciation, Schaefer says, in atoms that chronicle exposure to the elements. Earth’s surface is constantly bombarded by cosmic rays, high energy particles streaming into Earth from space. They collide with atoms in Earth’s atmosphere as well as in the uppermost centimeters of its rocks, producing new particles. Some of those particles have a particularly useful set of properties: They don’t naturally occur in the rocks, and they are radioactive. Thus, they can act as a sort of clock, marking time since the rocks were last ice free and exposed to the atmosphere.

Schaefer and his colleagues measured the abundance of two cosmogenic isotopes, aluminum-26 and beryllium-10, in grains of the mineral quartz that they found within the bedrock. Each isotope is produced at a different rate by cosmic rays and has a different half-life. Once the rocks are no longer exposed to the atmosphere—for example, buried by ice—the ratio of 26Al to 10Be in the rocks changes because of their differing half-lives. Schaefer and his team found that the ratio in the bedrock  was simply too low for the site to have remained buried continuously over the last 1.25 million years—suggesting that it had been exposed and ice free at least once during that time.

Schaefer says he is certain the findings show that Greenland was ice free at one point—but, he says, “we need to understand what happened and how it happened.” More cosmogenic studies of the bedrock, for example, could further narrow the dates of exposure. He finished his presentation with an appeal to other researchers: If you’re going to retrieve an ice core, consider getting some bedrock while you’re at it.

Well, show me a paper that says that Greenland was free of ice, some 12,000 years ago. That it had a sub-tropical climate, that its inhabitants had a bronze-age level of civilization, that they conquered most of (western) Europe, up to Egypt.

AND, that their island submerged, and left nothing but an impassible sea of mud.

Edit:

This was a question meant for Polar.

This is the untouched image of the center of the island, taken from a much larger image (about 20 MB). The longest canyon in the world starts there.

I would say that the average University professor IS NOT a geneticist. Where is the specific genetic analysis supporting his DNA claim.

Ancient Greenland was much warmer than previously thought

New knowledge helps researchers understand how Greenland's ice sheet responds to warming

Date:

June 4, 2018

Source:

Northwestern University

Summary:

Although researchers have long known that the last two interglacial periods experienced warming in the Arctic due to changes in the Earth's orbit, a mix of fly species preserved from these times in a rare lake sediment core shows that Greenland was even warmer than previously thought. This information could help researchers better gauge Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behavior.

A tiny clue found in ancient sediment has unlocked big secrets about Greenland's past and future climate.

Just beyond the northwest edge of the vast Greenland Ice Sheet, Northwestern University researchers have discovered lake mud that beat tough odds by surviving the last ice age. The mud, and remains of common flies nestled within it, record two interglacial periods in northwest Greenland. Although researchers have long known these two periods -- the early Holocene and Last Interglacial -- experienced warming in the Arctic due to changes in Earth's orbit, the mix of fly species preserved from these times shows that Greenland was even warmer than previously thought.[...]

Regarding your other two aspects of what Plato might have said about historical events, e.g. advanced civilization, or conquering Europe and Egypt, is a moot point, imo.
