Ice shove - Wikipedia
An ice shove, ice surge, ice heave, ivu, or shoreline ice pileup is a surge of ice from an ocean or large lake onto the shore. Ice shoves are caused by ocean currents, strong winds, or temperature differences pushing ice onto the shore, creating piles up to 12 metres (40 feet) high.
"Ivu" sounds like some legendary creature like the Yeti or Abominable Snowman. Abominable Ice Shove?
Anyway, I've never seen anything quite like this. It was reassuring - somewhat - that this is actually a "thing" and not some freakish nightmare driven by climate change. As per usual, this video (a couple of years old now) was passed around without any explanation. The tinkling crystal-chandelier sound has an undertone of relentless chugging, like an awful ice train. That part of it I don't understand, at all. It still looks like some supernatural event to me, like a glacier somehow sped up about a million times.
Blogger's annoyed post-script. I can't find a thing on "ivu" except in that Wikipedia piece. Wikipedia defines it very strangely:
From Wikipedia, the free encyclopedia
Ivu or IVU may refer to:
Ice shove (Inupiat terminology is Ivu), a surge of ice from large bodies of water onto the shore
Impuesto sobre Ventas y Uso, the Puerto Rican sales and use tax
International Vegetarian Union, a non-profit organisation promoting vegetarianism
Intravenous urogram, a procedure to examine the urinary system
Ivu or Eve, a character from the manga Black Cat
It isn't even a REAL black cat, but a person, and nowhere is she called Ivu. I give up.
