A the team of scientists on a NASA IceBridge video shared this week by a massive iceberg fell off the Pine Island Glacier, the latest event for the 68,000-square-foot glacier in Antarctica. Although they have not seen the real moment of rupture, the film helps illustrate the gigantic dimension of this new iceberg, which is one of the larger events of its kind in recent memory.
Generally, when an iceberg breaks out of a glacier-a process called a fetus-is a sign that there is a structural problem with the ice sheet. This is probably the case of the Pine Island Glacier, which has been worsened for the most 25 years.
In this most recent event, spotted by NASA scientists on Wednesday, a massive 115-square-foot rupture occurred, which led to a massive shedding of ice later. This latest event is the most recent of the feces of the Pine Island Glacier.
This new iceberg, called the B-46, broke away from the Antarctic Pine Glacier Island at the end of October, although we did not get any pictures until this week. When the first crack appeared, it was 115 square kilometers, which is approximately five times higher than that of Manhattan Island, but the largest individual iceberg is about 87 square kilometers.
When a glacier of the lower Manhattan size shed by Helheim Glacier in Greenland in July, Washington Post reported that 10 billion tons of ice fell into the ocean.
The workshop event this week is still defrauded by the iceberg A-68, which was more than 3,600 square kilometers Antarctica stopped in July 2017.
However, this week's event is still classified as another big birthday event.
On the contrary, there are other reasons for interrupting and reflecting on B-46 status. The glacier of the island of Pine has spread the ice several times during only five years: once in 2013, once in 2015 and one in 2017, which adds an alarming amount of ice flow. These icebergs do not simply remain: they can float in more populated waters. For example, the ice spilled from the Jakobshavn Isbrae Glacier in Greenland is rumored to be responsible for the Titanic's sinking in 1918.
The following pressing concern about these calving events is likely to contribute to raising the sea level. NASA highlighted on Thursday that the glacier of the island of pine is the fastest melting glacier in the Antarctic.
