The life and melt of Iceberg A-68A

 



A few months ago, when Iceberg A-68A was headed toward a potential collision with South Georgia Island, which had the potential to mess up the subpolar ecology of that archipelago, I posted a few snapshots from the NASA Worldview site that showed the approach -- and then the somewhat unexpected crack-up and fragmentation.

After some of the pieces went hither and yon (more hither than yon), I stopped keeping track.  Well, it turns out that quite recently, the final remnants of the formerly massive and magnificent A-68A did what all icebergs eventually do -- they succumbed to the warmth of the water, and returned to it.

The NASA Earth Observatory has graciously provided a chronicle of the birth, journey, and demise of A-68A.
