Glacial iceberg shifts revealing the deep blue of older, compressed ice

u/Morgankgb 15h ago
I’m obsessed with these shades of blue. So, for those wondering, the iceberg is darker at the bottom because it’s been underwater longer, and all that pressure from the water compresses the ice. This squeezes out air bubbles, making it denser and more transparent. Denser ice reflects less light, which is why it looks darker. The top part is looser, with more air in it, so it reflects light better and looks white

So how old would the lowest level of ice be?

Hundreds of thousands of years

In the whole world it’s millions.
Scientists have successfully drilled a 2800-meter-long ice core, containing ice from the Antarctic ice sheet that is more than 1.2 million years old

A truly deep blue that almost looks black
But that’s extremely ideal conditions that I’ve on earth likely can’t ever reach

None of that relates to the color blue, though.
For what reason does this compressed thing become blue? Why not yellow or orange?

Receding glaciers are more alarming than satisfying.

Most glaciers have a yearly cycle of growth in the winter and recession in the summer, so a glacier shedding ice isn’t in itself an alarming thing.
The problem is that, year on year, glaciers are receding further and not growing back as far.

Right? I feel weirdly anxious.

I honestly feel like... Queazy if I watch it too long. I wanted to see the pretty blue but had to keep looking away, like the whole thing was a jump scare

what causes that deep blue colour?

u/JAnonymous5150 15h ago edited 7h ago
The compressed ice crystal matrix causes the ice to absorb more of certain colors/wavelengths of light and scatter/reflect more of the blue color light wavelengths making it appear more blue. The effect increases with more compression so the more compressed the ice is, the deeper the blue color will be.
That's how it was explained to me, anyways.

freudian_nipps, I have seen many times the upload of an other person's work and you refuse to include the source. I found source in 1 minute using the Google Lens search. I think you are lazy and disrespectful. Please always include the source.

Laxy and disrespectful is a bit of a stretch. Doubt its intentional. However, people reposting tik tok videos need to be euthanized.

u/Historical_Cheek_502 1h ago
It is the intentional I believe. I looked at this history of posts and they always steal a content to put on more than one subreddit and they do not include the credit. Before I said to fruedian_nipps to include the credit and I become ignored.
I take 1 minute to find the credit. It is not an excuse. It is lazy and disrespectful.

I understand I think. You do not believe it is lazy and disrespectful because stealing of a content of an other person and not including the credit is ok you think.
You are a person with no value. You have no value to steal so you do not experience the value to be taken from you. Steal an other is the thing you only understand so it is likeable.

The deep blue color is stunning! It's amazing how the compression over time creates such a vivid hue.

while the sub is not that active, if you scroll down a bit you can see some posts with really good footage ( even this video but in real time, not slowed down - posted a couple years ago)

What always blows my mind is how deep the glacier goes. Literally only a fifth or less is above the water surface.

Reminds me of the scene from dune with the atreides ship rising from the ocean. Totally wild shit man!

That’s in the past. We can’t change it. Some of the worst acts in humanity? Yes! But nothing can be done about that at this point. We can still change the future, but time is running out. We are in the tipping point right now. If we don’t act soon, we won’t be able to

When we were on an Alaskan cruise, we took a small boat near the glaciers. We reached into the water and grabbed some of the smaller bits of ice, and put it in our cocktails. It was perfect.

Food for thought: there are for certain meteorites in that ice that are older than earth.

if water has no colour how come iceberg blue
1
u/Safe-Ad4001 8h ago
Because of sunlight. The compression of water molecules refracts the lightwaves.

Cleanest water on Earth. I hiked the glacier and brought a case of water, dumped it and filled them all with the glacier goodness

such a beautiful color oh my
And for the record, the glacier is breaking off which causes the shift. Meaning that this iceberg likely will slowly be drifting away to melt. The glaciers are dying.

The ice people have decided to surface and teach us their peaceful ways? Like in Abyss?

If it’s denser and therefore heavier on the bottom, how does it flip like this?

u/skoltroll 15h ago
And I said, "What about Breakfast at Tiffany's?"
She said, "I think I remember the film and as I recall, I think we both kinda liked it."
And I said, "Well, that's the one thing we've got."

I believe this is a video from Exposure Labs, and it appears to have been edited.
Largest Calving Event Ever Recorded
Really incredible footage, if you haven't watched it you should.
Edit: I rewatched, it doesn't appear to be the same video lol. Nonetheless, both are incredible.
