The Movement of a Colossal Iceberg Helped Scientists Discover what Lives Underneath it


A Delaware-sized iceberg, in July 2017, detached from the ice shelf of the Antarctic. It did not travel too much over the next year, but at the moment it is headed north offering scientists the opportunity to study what lives in the never-before-studied ocean ecosystem which lives under an iceberg.

The iceberg is on the move

The iceberg has been photographed by a satellite over the past few months, and it has rotated counterclockwise at about 90 degrees. It was named A68, and its movement is unlikely to stop, based on a polar oceanographer’s, Mark Brandon, statement.

He believes that A68 will not stop rotating because it is close to the western point and got it to stop the northern edge must collide with the Larsen C ice front. The iceberg can’t be easily stopped because of its spectacular amount of momentum.

Why did the iceberg go on a trip?

Martin O’Leary, a glaciologist, has a couple of theories which stay behind the reason why the iceberg started moving.

The glaciologist says that ocean currents or winds shook it loose or it is just because of the natural process of thinning which occurs from the flow of the ice and melting that is lifted iceberg’s bottom off the seabed.

The wonderland it left behind

As A68 keeps moving towards the sea and rotating, its destination is unknown. However, researchers are left to a new ecosystem to study.

A doorway to a pristine underwater ecosystem was left open after A68’s departure. Predictions established by researchers suggest that this ocean’s area was undisturbed for 120,000 years and changes could take place before the outdoor conditions and sunlight exposure.

Will the dinosaurs emerge from there? Probably not but new life might be born anyway.
