The world’s largest iceberg, A-23A, and stones News of news
The world’s largest iceberg, which is trapped in the shallow water of South Georgia island, is losing its edge, waves and declined through the last southern summer.
The modis of the NASA Aqua satellite (moderate resolution images of the spectrimanometer) seized this picture of the iceberg, known as A-23A on May 3, 2025. South Georgia has a ice bar less than 100 km from South Georgia, a remote island in the South America.
The lower part of the iceberg is likely to be on the underwater stage around the Georgia Dell Sur, which is known for hooking up several Antarctic icebergs in the north side of the southern Atlantic. The satellite images show that the iceberg has been unconscious since the beginning of March 2025, NASA reported.
It loses an area like Washington twice in two months
Although its position does not change practically, the iceberg surface has been significantly reduced in just two months. According to Icebergs data from the US National Ice Center of the US (USENIC), A-23A lost more than 360 sq km between March 6 and May 3, and the area is twice as much as Washington DC.
Thousands of icebergs are scattered on the surface of the sea near the main iceberg, which creates a scene of dark and stars night. Although these fragments seem to be small in the film, most people measure at least one kilometer of diameter and indicates the risk to ships. One part, A-23C, is large enough to give a name to Usnik after being separated from the southern side of A-23A in mid-April.
The detachment of these icebergs occurred somewhat along the trajectory of A-23A, even when rotating the path of drake in 2024. However, there are indications that the iceberg is becoming a fragile. Therefore, the frozen strip is on its north side, which suddenly the remains of “Edge dress”, a few days of warm and sunny weather.
About 55 degrees South latitude, the iceberg is away from the softest Antarctica waters, which has contributed to its conservation since it was separated from the Filk Ice Platform in 1986.
Edge dresses are one of the three types of icebergs observed by scientists through satellite images.
This occurs when small pieces of ice are separated from several points on the edge of the iceberg, reduced its area and retain its normal shape. The icebergs can also break many large fragments or completely. Whatever the way to follow the A-23A, the duty of this environment is practically uncertain.
The icebergs of Antarctica follow more than 90 % of the same path: they enter the Weddel Turn Current, which flows on a schedule, compared to the Eastern Antarctica, and they go to the north of the Antarctic Petter and cross the route of the southern Atlantic’s warm waters. They are melting all week.
