During Operation IceBridge's October 16 aerial survey, in addition to finding that now-viral iceberg, (sometimes referred to as tabular A) senior support scientist Jeremy Harbeck also spotted one other rectangular berg floating by.
The new image, which was shared by NASA on Tuesday, shows the famous sharp-cornered iceberg appearing by the engine of Harbeck's plan as its twin (let's call her tabular B) takes center stage. The A-68 iceberg can also been seen in the distance.
According to NASA officials, the rectangular icebergs appeared to be "freshly calved" from Larsen C, which the parted ways from the iceberg now known as A-68 parted in July 2017.
"I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had," Harbeck said.
Operation IceBridge is the longest-running aerial survey of polar ice, according to NASA. The program is part of an overall effort to document changes in ice sheets. Harbeck's October 16 flight is part of a five-week long deployment that is scheduled to end November 18.
