Out of curiosity, I wanted to find out how long the grounded iceberg stayed before it finally went away.
Amazingly enough, it was more than a year!
It calved at the end of July 2015 with most of the calved ice disappearing away. The grounded part broke up mid-August with another piece floating away, and ever since then our PIG-headed iceberg just kept holding on.
Would it be fair to speculate that the glacier is partially grounded at this area? If a calved iceberg can stay grounded for so long, it must mean it was grounded before the calving as well.
To entertain more idle speculation, would the calving and subsequent removal of this iceberg reduce the buttressing of the PIG?
