The United States Space Agency (NASA) has published several photographs taken on a mission in Antarctica of two icebergs with an unusual and striking rectangular shape, which has become a phenomenon in social networks.
The discovery was made during one of the flights carried out by the so-called Operation IceBridge on October 16, considered by NASA as the largest aerial study conducted on polar ice, says this agency on its website.
The aforementioned study has been designed to evaluate the changes in the height of the ice of several glaciers that flow into the Larsen A, B and C and, during its realization, one of the scientists of NASA, Jeremy Harbeck, saw a tabular iceberg of very sharp angle that floated among the sea ice right next to the Larsen C ice shelf, cites this institution.
"I thought it was interesting, I often see icebergs with relatively straight edges, but I really had not seen never before one with two corners at angles as straight as this"says Harbeck.
According to NASA, the rectangular iceberg appeared to have emerged from the Larsen C glacier, from which in July 2017 emerged a giant block of ice the size of the US state of Delaware (almost 6,500 square kilometers) that was dubbed "A68".
In his photographs, Harbeck captured both the edge of the now famous iceberg and a block of ice a little less rectangular and, in the distance, also appears the "A68".
"Actually, I was more interested in capturing the A68 iceberg that we were about to fly over, but I thought that this rectangular iceberg was visually interesting and quite photogenic, so at least I took a couple of pictures," Harbeck said.
The NASA flight departed from Punta Arenas, Chile, and the five-week mission began on October 10 and is scheduled to conclude on November 18.
