A glacier table on the Black Rapids Glacier, Alaska Range. The boulder insulates the ice beneath it from melting, while the surrounding surface melts down, leaving it perched on a pedestal. Eventually, the pedestal becomes unstable, and the rock topples, and the process starts again.

Anyone have any clue where I can get a measuring tape for sea ice in Europe? The only supplier I have found is the very lovely and friendly Kovacs, but they are US based and the cost and time for delivery are crazy.
I mean one like this:

The Gabriel Icefall on the Gulkana Glacier, Eastern Alaska Range. About 400 vertical feet of ice in this frame. The striations are annual accumulation layers that become folded during flow. Towering seracs form where crevasses intersect as the ice is deformed over the steepening terrain.

Interesting endeavour! As mountain glaciers melt, their trapped gas and also pollen records first blur by meltwater intrusions – and then vanish completely in the melt process.

French and Italian research institutes and the Albert of Monaco Foundation banded up to collect and preserve 20 ice core samples from mountains around the world. Storage site: a 10m deep dug-out ice cave near their 🇫🇷 🇮🇹 Concordia Station in #Antarctica
The core archive will be open-access to every researcher globally, provided they get to the location.

At -52°C inside the cave, melting of the cores is prevented. But natural ice flow processes – Antarctica isn't a static clump of ice – will require someone to dig a new cave every 60 to 70 years and move the cores. (Or invent a storage site that can withstand the glacier flow?)
I searched for that bit of information specifically and found it at min. 37 in the inauguration video https://www.ice-memory.org/ice-memory-foundation-/press-release-inauguration-of-the-ice-memory-sanctuary-in-antarctica-1698645.kjsp?RH=1832088615308700

Another example of how Antarctica isn't a static clump of ice: to counter the ice flow movement, the actual pole at the South Pole gets dug out New Year,'s and stuck back into the ice 10m back: https://www.scientificamerican.com/article/the-south-pole-just-moved-heres-why/

The Last Ice Memory: The Race to Core the World’s Glaciers Before They Vanish

Time is running out for Earth's frozen archives. In 2026, scientists are racing to core the world's most endangered glaciers before they melt forever.
