OMG! Colossal Iceberg Breaks Away From Antarctica (Video)


Colossal Iceberg, “Larsen C”, Breaks Away From Antarctica


Iceberg Larsen C, finally breaks from it’s larger ice shelf

An iceberg weighing more than 1.1 trillion tons, began to split in 2014. It started with small fissures. Soon huge gaps spread between the ice. Glaciologists watch glaciers and ice shelves over long periods of time. This one, in particular, was static for decades.

Recorded increment movements, accelerations as well as major shifts notifies the glaciologists of the minutest changes. The crack noticed in 2014 was just the beginning of the calving of the Larsen C shelf. Since that time, the crack expanded. It traveled north and multiplied the distance from the remainder of the Larsen shelf.

When calving of this magnitude occurs, it affects the ice shelf barrier that connects to it. In turn, this affects the glaciers directly feeding it. Larsen C is one of the largest recorded icebergs to date. It is the size of Delaware and measures 5,800 square kilometers.


Between July 10th and July 12th, the split of Larsen C from the larger shelf occurred

This break redefines the border shape of the peninsula completely.  Larsen C was attached to a bigger shelf which in turn is fed by a glacier. Most often any calving that occurs is legitimate.

Effects of these breaks in the ice are minimal and just part of nature. Most scientists who have studied the rift don’t anticipate any world catastrophe. These are natural occurrences.


They shouldn’t cause any trouble

Certainly, the possibility exists for the sea levels to rise, or the mother shelf to be affected. Even the glacier could have repercussions. However, the rate the shelf is moving doesn’t indicate a problem. It will most likely stay in the general area or break into fragments that will migrate to warmer waters.

Temperatures, ocean currents, waves and winds might impact rift growth or deterioration. These external factors are always taken into account when scientists evaluate their data.


NASA acquired images

NASA has images from its Aqua MOPIS satellite equipment. This instrument takes thermal infrared pictures. Other options for measurement include airborne surveys, automated geophysical instruments, satellites, thermal imagery and relative field work.

The continued study of icebergs, global warming, shifts in the earth, tsunamis, all kinds of natural occurrences are monitored and explored. That is to say; scientists continue their evaluations and searches for interesting changes in the earth’s surface.


We should not be afraid of the changes

Being aware of what is happening around us is important for the continuity of our civilization. Not every change in the world commands us to respond in panic and attitudes of impending doom.

It’s good to know what is happening in Antarctica. Just as important is what is happening in your neck of the woods. Consider yourself informed and educated about planet earth.
