Ice cores are a few inches across. The photo at the top of the article is not of the drill hole but of the hole they had to dig in the snow to get to the ice they actually drilled.
See the photo of the final ice core [1] to see how miniscule the actual drill hole is.

- Giorgi 3y agoWhy is is black and white though? also - how do they transfer energy to drill down 2.7km? or how the hell does it work?
- TheRealPomax 3y agoSee other comment, and "that's a fun thing to check youtube for", respectively =)
- tgamma 3y agoAs mentioned in the article, the core was handled under red light to prevent any potential damage. Perhaps the decision to convert the photograph to black and white was made because otherwise it would have been black and red.
- blackkettle 3y agoThe article definitely makes it sound like they had “boots on the ground”. There’s a picture of muddy boots and the caption says they are covered in ancient mud.
- tokai 3y agoThat mud came up with the last core.
- TheRealPomax 3y agoYou need to clear a lot of snow before you can stand on the ice that you're drilling in (You can't drill straight if your rig's sitting on snow, you need to dig until you hit solid ground, and in this case the ground is ice). That's the "boots on the ground" part. They were physically there to do the drilling (as opposed to giant automated core drillers such as DISC[1], which don't require "boots on the ground" so much as they just require one or more operators to oversee operation) The ancient mud's from hauling up the ice cores, not from standing 3 kilometers deep in a giant hole.

- blackkettle 3y agoI’m not disputing the reality; it would be a bit ridiculous and I assume incredibly dangerous especially given the rate at which the whole thing is moving. I’m just arguing that the article is worded in a way that is encourages such a misunderstanding.
