UPDATE on the B15 Series of Mega-Bergs
Just Look at that old Mega-berg...

It's still almost as large as South Georgia Island, well, at least it's still on the same scale as South Georgia, and dwarfing the South Sandwich Islands to its East & Southeast, even after floating around for 18 years...

Famous Rectangular Iceberg’s Rough Journey,
NASA Earth Observatory, November 5, 2015.


"...spotted Oct 16..."

"...it was reasonable to assume it might have very recently calved from the Larsen C ice shelf. That’s the same ice shelf that spawned A-68, the trillion-ton iceberg that broke away in July 2017."

"They found that it calved from the ice shelf’s new front in early November 2017, just a few months after A-68 broke away."

"The berg cruised all the way north and through a narrow passage between the A-68’s northern tip and a rocky outcrop near the ice shelf known as Bawden Ice Rise."

"The once-long rectangle berg did not make it through unscathed; it broke into smaller bits."

“Now it’s just another iceberg on its way to die.”



This cute little tabular berg above, is to the A-68 series of bergs, as a mosquito is to bears.
