In Antarctica broke new giant iceberg

After hottest temperature now iceberg breaks off in Antarctica

After hottest temperature now iceberg breaks off in Antarctica

Sound familiar? That's because it probably is.

The Pine Island Glacier recently spawned an iceberg over 300 sq km that very quickly shattered into pieces.

A huge iceberg has calved - cracked off - the Pine Island Glacier (know as "PIG" for short) in Antarctica, according to a report today (February 11, 2020) from ESA, . Sentinel satellite missions have been keeping a close eye on two large rifts in the PIG, spotted previous year.

Over the next few months, as the glacier moved out towards the Amundsen Sea, the rifts expanded, eventually leading to the splitting of the iceberg from the glacier on February 9.

This is one of the largest ice streams in Antarctica which flows together with Thwaites Ice Stream into the Amundsen Sea embayment in West Antarctica. The largest "piglet" has been labeled "B-49" by the ESA, signifying the mass's importance in terms of future monitoring for researchers. Pine Island Glacier is hard to access and since it is remote from any research bases, so flying there means making multiple short flights, making fuel depots to allow scientists to hop to the location.

In October a year ago scientists noticed appeared on the glacier cracks which became wider. "Since the early 1990s, the Pine Island Glacier's ice velocity has increased dramatically to values which exceed 10 meters (or 30 feet) a day", the space agency said in a news release. But since 2013, the glacier has calved five times, according to Stef Lhermitte, a remote sensing scientist from the Delft University of Technology in the Netherlands. "Its floating ice front ... has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front". However, the rate of melting and calving in West Antarctica is greater than is being observed in the satellite record. Last week, a region in the North West reached over 18 degrees Celsius (65 degrees Fahrenheit) - nearly a full degree higher than the previous record from five years ago.

On its own, the recent calving event is not entirely surprising or particularly threatening to global sea levels; calving is a normal part of life for ice formations with sections that float on the water, according to NASA's Earth Observatory.

He said he hopes the images would continue to be an "eye in the sky" to monitor glacial change and improve public knowledge.
