hit the Drygalski ice tongue in mid April, knocking off a chunk of the glacier. The berg then got stuck in Vincennes Bay for a month, but is now moving off
Scientists will continue to monitor the iceberg, but it is unlikely to disrupt the movement of penguins and ships.

Almost the entire mouth of the sound had been blocked before B15a took off, Brunt said. Two other giant bergs, B15k and C16, are still blocking about 60 percent of the entrance to the sound. But that’s a big improvement. “B15a is out of the way and that’s a good thing,” said Marianne Okal, another graduate student with the group. “I’d be surprised if there’s still 85 miles of sea ice out there next December.”
There is, however, a new iceberg resident inside McMurdo Sound.
The interloper is about 16km long and 2km wide, Weidner said. It got within 60km
of McMurdo Station, but backed up so that it’s about 90km away now,
The berg shouldn’t affect any penguin colonies, he said. Nor should it interfere with the ships moving in and out of station in January.
