The team's next steps include looking more closely at specific ocean swell events and sea ice conditions during known ice shelf collapses and
large iceberg calving events.
The last time
a large iceberg calved from Antarctica was in 2002, when a chunk about half the size of the Larsen C iceberg calved from a different ice shelf on the Antarctic Peninsula, Larsen B (SN: 3/30/02, p. 197).

This is a 2001 image and the

The heavily crevassed surface (extending to the distant horizon) of Jakobshavn Isbrae, one of Greenland's fastest outlet glaciers, is shown on this

In part because the
large Jakobshavn Isbrae moves so quickly, it is difficult to tell the glacier ice (right and top) from the many
icebergs it has
calved off (center front) into the fjord.
It is conjectured that this strong AABW freshening seen in 2016 may have been due to changes associated with the 2010
calving of the Mertz Glacier Tongue along the George V / Adélie Land Coast that resulted in the ungrounding of a
large iceberg.

Icebergs rarely form in this manner; in fact,
large calving events happen just once every 40 — 50 years.
Icebergs form when chunks of ice
calve, or break off, from glaciers, ice shelves, or a
larger iceberg.
This was the second
large calving event off this glacier in just two years: the
iceberg that broke away in August 2010 was twice as
large.
