Talk:2902: Ice Core

Akin to 2729: Planet Killer Comet Margarita, which perhaps needs mentioning in the upcoming Explanation... 162.158.74.118 23:04, 4 March 2024 (UTC)

Added a short explanation, but it'll definitely need more work. 172.70.210.235 23:11, 4 March 2024 (UTC)

The title text raises a lot of questions. It's a play on the mixed drink Long Island Iced (or Ice) Tea of course. But why the underscore? Why does the T look funny (tau?)? Why isn't tea spelled out?172.69.6.189 23:44, 4 March 2024 (UTC)Pat

Yes, Randall did use tau in the title text. I recently made mention of that in my most recent edit. I'm not sure why he used it but maybe instead of a "Gone Island Ice Tea", it's a "Gone Island Ice Tau"? OmniDoom (talk) 23:58, 4 March 2024 (UTC)

Tau is tortuosity in a lot of equations involving porous material (including ice), and also represents time in some engineering disciplines. It's written as "Ice_τ", and I have no idea what the oddly specific underscore is. Maybe it's "I x c x e" from some equation that involves τ? And somehow could be relevant to a sunken island? 172.69.58.152 00:05, 5 March 2024 (UTC)

It could be the case that the underscore before the tau is indicating a subscript and that, as you said, the "Ice" could be "I * c * e_τ" but I have no way of being sure. (Quick aside: I originally read the "I x c x e" expression as though it were "Ixcxe" and took it for a word or an acronym or something. Humanity really needs to agree on a universal form of multiplication sign for typing.)OmniDoom (talk) 00:28, 5 March 2024 (UTC)

Aside cont.: We already have a character specifically for this: × (U+00D7 MULTIPLICATION SIGN). How to type that is an exercise left to the reader. 172.68.19.94 01:01, 5 March 2024 (UTC)

I've heard recently (possibly reheard, as (amongst other things) I've been relistening to The Infinite Monkey Cage broadcasts/podcasts but can't immediately pin down the remembered context) about ice-core samplings having been used as drink-ice. But this is thousands-of-years-old ice, with thousands-of-years-old atmosphere trapped in it, as bubbles that get released as it melts. It was supposed to be special, given that (with a bit of poetic licence) you could technically breath in the ancient atmosphere with a good sniff at the glass. Though, as might not be surprising, the taste was described as "like drilling fluid". 172.69.195.156 02:24, 5 March 2024 (UTC)

Is it really possible to date ice layers to specific years? I assume dating precision is millenia, maybe at best centuries. The explanation should mention how impossible it is to date to a specific birth year, unless there happened to be a specific climatologic event that year (like a big eruption).

If compressed (centuries or more of snow atop), it might be more difficult, but this is going to be maybe a handful of decades of layers. Depending upon the local buildup method (still snows a bit during the long (ant)arctic night, then (ant)arctic day gentle crisps the surface snow), it might be fairly obvious under visual inspection. Even without key marker deposits from atmospheric dust/soot/etc. But would depend upon both weather and climate patterns. 172.69.194.242 04:39, 5 March 2024 (UTC)
