Operation IceBridge, NASA’s longest-running aerial survey of polar ice, carried a flight over the northern Antarctic Peninsula on Oct. 16, 2018. During the flight, IceBridge senior support scientist Jeremy Harbeck spotted two rectangular icebergs floating among sea ice just off of the Larsen C ice shelf.
“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.
The rectangular iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the massive A68 iceberg, a chunk of ice about the size of the state of Delaware.
“I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple photos,” Harbeck said.
The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began Oct. 10 and is scheduled to conclude Nov. 18.
