A trough beneath Denman Glacier is the deepest continent point in the world, measuring more than 2 miles beneath sea level.
Scientists have known for years that Denman Glacier, a very large glacier in East Antarctica, has a trough beneath it, but they had no idea just how deep it was until glaciologists at the University of California, Irvine, mapped the region. According to this recently compiled a sophisticated map of the icy continent, this trench is actually two miles (3.5 kilometers) below sea level, which practically makes it the deepest point in the world.

Mathiew Morlighem, the lead author of the new study and an Associate Professor of Earth System Science at UC Irvine, says work on the recent topography map of Antarctica, known as BedMachine, started years ago almost by accident.
Morlighem and colleagues at NASA were designing models of ice sheets when they noticed that their simulations contradicted reality in some key aspects. For instance, some glaciers that were known to lose mass were suddenly gaining mass according to their models. Upon investigating, they found that it wasn’t bad math or the model’s resolution to blame, but rather the shape of the bed.

and if the ice melts, it will fill with ocean water and stop any water rise...

Isn’t it filled with frozen water now?
Whatever proves that we need to raise taxes, go with that.
Interesting. A canyon filled with liquid water is nothing special. But a canyon filled with solid water is!
“Upon investigating, they found that it wasn’t bad math or the model’s resolution to blame, but rather the shape of the bed.”
You made your bed, now lie in it.
I think we call that ice.
The watermelons predicted back in 1995 that the world’s coastlines would be under 20 ft. of water. Didn’t happen. They keep pushing this hoax on a new crop of dipchits and now we only have 10 years until the end of the world. They’ve made a monumental mistake. Because in 10 years nothing will have changed. They should have stuck with the 30 year generational line.
——Glaciologist?——
One who studies glaciers
Geologist....... One who studies rocks and geology
Herpetologist........ one who studies snakes
Ornithologist....... one who studies birds
Ichthyologist....... one who studies fish
Entomologist...... one who studies insects
Don’t forget proctologist.
"Huh?"
A couple of questions spring to mind:
One, is this “canyon” inland, or is it just a fjord that the glacier completely fills?
How much of the depth is glacial activity, and how much is just the weight of the glacier pushing down the rock?
Not really. Some fjords are frozen canyons winding their way to the leading edge of a glacier.
This one does not seem to have an outlet and is deeper.
Wrong!, trans women, women of color and lgblts are at a higher risk of failing into that trench, since President Trump stole the election.
That deep below sea level should be warm enough to melt ice so I don’t think it could be completely solid.
What kind of fishing lure is that gonna take?

I saw what you dd there.
