The Birth of the 100 square miles Ice Island
Something stirs my imagination
This scientific phenomenon of the huge arctic iceberg which I first saw in the World Atlas Facebook a few days back captivates my imagination. It drives me to seek its details so as to have a concrete idea of what the thing really is. I learned that it was a huge chunk of ice that has separated from the ice shelf in Greenland. Its size and height staggers the imagination.

Acquired August 5, 2010 , and July 28, 2010, these natural-color images show the Petermann Glacier before and after the calving of a massive iceberg.
Ice calving is the breaking off of chunks of ice at the edge of a glacier. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as:
- iceberg, but may also be a
- bergy bit, or a
- crevasse wall breakaway.
Ice calving is likewise called:
- glacier calving or
- iceberg calving.
Causes of calving are classified into:
- Longitudinal stretching;
- Melting at the waterline;
- Tidal and seismic events;
- Buoyant forces
- Melt water wedging
Sounds during calving
Loud cracking sound accompanies calving of glaciers before huge blocks of ice break loose and crash into the water. The entry of the ice into the water makes big and often dangerous waves
Most glaciers terminate at oceans or freshwater lakes which results with the calving of large numbers of icebergs.
Calving of Greenland's glaciers produce 12,000 to 15,000 icebergs yearly
A rift usually precedes calving of ice shelves.
"Cold Eyes" [Free verse]
For the purpose of this free verse, I have this 100 square miles ice island named “Cold Eyes” which features most of the facts I have gathered. I am reminded of the 1912 RMS Titanic sinking caused by an iceberg. I pray to Almighty God that such a catastrophe never to happen again.
This fifth day of August two thousand and ten
Angels with trumpets blared Hear Ye! Hear Ye!
Baby COLD EYES is born in far off Greenland
While Thunder bolts clasp and hug him close all day
Lovingly Mother Glacier wraps him with the balmy sea
Baby COLD EYES whimpers C-r-a-a-a-k! UHA! UHA! UHA!
Tell mankind to curb global warming, forest denudation, etc.
If not, brothers upon brothers of my kind will calve to follow suit;
They weigh COLD EYES to record his vital stats
So gargantuan is he who measures 260 square meters
Akin to 100 square miles or 4 times the size of Manhattan
The Empire State Building is a 102-story landmark
Half this building is the height of COLD EYES
Born with him is enough freshwater which is calculated
To keep the Delaware and Hudson rivers flowing for 2 years up
Likewise, he could keep all US public tap water flowing for 120 days,
Said Andreas Muenchow, research leader from the University of Delaware
Muenchow further said “Cold Eyes” could block the Nares Strait,
Or break into smaller “Cold Eyes” and continue towards the open waters of the Atlantic
Here in Philippines, COLD EYES has its distant ilk
They’re machine- made ice blocks from ice plants
Enough for a brawny man to lift onto his shoulder
They end up in cold storage to keep fish and fruits fresh
Crushed into tidbits and mixed with milk, beans, mango and avocado
Call it mango shake, avocado shake, fruit shake or halo-halo
And- in between spoonful- makes you quip, “SARAP” (Delicious)
COLD EYES, within the next 2 years, returns from whence he comes.
