or cow (or moose or seal or whale) calving?
Hmmmm. Let's go with ice calving. Check out this largest filmed ice calving event at the Ilulissat Glacier in Greenland.
Ice calving, also known as glacier calving or iceberg calving, is the breaking off of chunks of ice at the edge of a glacier, iceberg, ice shelf, or crevasse. The ice that breaks away is classified as an iceberg, but may also be called a growler or bergy bit.
Growlers are smaller pieces of ice, generally rising less than a meter above water level, that make a growling animal sound as they move in the ocean. Bergy bits are mini icebergs that rise up to 4-5 meters above the water level.
Ice calving has gotten lots of attention lately as a result of global warming (See the 2014 documentary Ice Chasing).
And perhaps watch it with this kind of beer growler:
Do you suppose there's any connection between the sound of cows birthing and the sound of ice calving (the latter term first originated in Denmark in 1837), growlers and all?
Enjoy that ice calving blue; looking forward to your insights,
