Massive Crater Discovered Under Greenland Ice

Показать описание
In a remote area of northwest Greenland, an international team of scientists has made a stunning discovery, buried beneath a kilometer of ice. It’s a meteor impact crater, 300 meters deep and bigger than Paris or the Beltway around Washington, DC. It is one of the 25 largest known impact craters on Earth, and the first found under any of our planet’s ice sheets. The researchers first spotted the crater in July 2015, while they were inspecting a new map of the topography beneath Greenland's ice sheet that used ice-penetrating radar data primarily from Operation IceBridge, an ongoing NASA airborne mission to track changes in polar ice, and earlier NASA airborne missions in Greenland.

This appears to be possible evidence for the impact theory starting the Younger Dryas. For those that don't know, during the last interglacial warming period around 14, 500 years ago there was a sudden cold snap where instead of warming, the Northern latitudes drastically cooled for around 1000 years. Evidence we have of this period suggests that a large influx of freshwater changed the salinity levels of Northern ocean water to be less salty and thus less dense, causing the cold Northern water to not sink and thus not continue the cycle of convection for ocean circulation. The freshwater forcing on the ocean surface hampered the formation of North Atlantic Deep Water reducing the meridional heat transport, leading to cooling at high northern latitudes. This era of cooling is called the Younger Dryas period, and there is debate as to what exactly caused it. Which brings us back to the impact theory, as stated in the video, a large impact would have melted a vast portion of the ice caps allowing a huge influx of fresh water into the ocean.

- I am a senior writing a thesis on the Younger Dryas period.

So Graham Hancock and Randall Carlson were right all along.

I wonder how many such craters still hide underneath natural camouflage

"It could have hit from 10000 years ago to 3 million years ago."
Well, that narrows it down...

Randal Carlson / Graham Hancock who what!

I hope they narrow down the date of impact.

This would fit with the theory that large asteroids stuck the northern hemisphere's ice packs 12kya which triggered massive coastal flooding, altered global climate patterns, and brought an end to the last ice age.

Frightening to think how recent and numerous these impacts are. There’s been so many close calls even recently that you have to think it’s only a matter of time.

How good is NASA, not only pushing us forward but maybe helping uncovering one of our greatest secrets of our past. So much respect!

Maybe that event played a role in wiping out North American and European Megafauna.

Anyone think that this could help explain ‘the great flood’ found in ancient texts from around the globe? Or would the vaporized ice not have a significant effect to the sea level?
