Manhattanan iceberg more than 20 times bigger, this week Antarcticain Brunt Ice ShelfHe left. British Antarctic Surveyhuge iceberg separated by 1,270 square kilometers in length and 150 meters It covers an area of thickness.
BAS scientists The Day After TomorrowHe had an eerie aerial view of that scene at the beginning of the movie. Same time LOW scientists have seen three major cracks have formed in the floating ice field over the past decade.
Draws attention to climate change from BAS
Warning signs of an impending ice breaking event last November Northern Rift the emergence of a new chasm named and 35 kilometers It happened as it started moving towards another large fissure in the northeast.
January in, the rift advanced in that direction, at a speed of 1 km a day, and February 26It expanded substantially within hours of 1936, causing the iceberg to cut itself. According to the European Space Agency, Brunt Ice Shelf, 1971hasn’t seen such a big ice break since.
In addition, BAS Director Jane Francis stated in a press release that the organization has been waiting for this day for a long time. Francis “Our teams at BAS have been prepared for years to break an iceberg from the Brunt Ice Shelf. “We monitor the ice sheet daily using an automated network of high-precision GPS devices surrounding the station, which measure how the ice sheet is deformed and moving.” said.
According to the resulting report, this incident Halley Research Station It poses no immediate threat to the base known as. However, scientists continue to monitor the situation.
BAS operations director Simon Garrod said in a statement on the subject. “This is a dynamic situation. Four years ago, we moved the Halley Research Station inland to ensure it wouldn’t move when an iceberg formed, it was a wise decision. Our job now is to closely monitor the situation and evaluate the possible impact of the current ice rupture event on the remaining ice sheet. We are constantly reviewing our contingency plans to ensure the safety of our staff, protect our research station and maintain the presentation of the science we undertake at Halley ” said.
This iceberg 2017in Antarctica Larsen C Ice Shelfand lately South Georgia Island threatening to collide with and 5,800 square kilometers It is stated that the gigantic stack, one of the largest heaps ever recorded, has remained small on the air.
While rapid climate change is pointed out for such dramatic ice breaking events, scientists have made it clear that they could also be natural events. In the life cycle of an ice sheet, the ice grows large enough to no longer support itself, collapses, and then the whole process begins again.
LOWthis is the last iceberg Larsen C Ice Shelf He stated that there is no evidence linking the ice break event or the effects of climate change.
As for what happens next, it is stated that the iceberg will need to be monitored if it gets too close to commercial shipping routes or if it breaks even more. While climate change does not directly cause clumps to break, the rising temperature of waters and changing flow patterns can certainly affect where it goes from here. In any case, it will gradually break up into smaller pieces and live indirectly until the smallest icebergs also melt.
