Trillion-tonne iceberg snaps off Antarctica ice shelf
A 30-million-tonne iceberg – one of the largest ever recorded – has moved away from Antarctica after many months of anticipation and may now pose a serious threat to ships across the South Pole, the scientists announced today.
The birth of the 5800 square kilometer iceberg outside the Larsen C ice shelf reduced by more than 12% in the region and the landscape of the Antarctic Peninsula has changed forever.
Icebergs in Antarctica soak up the sun all the time, but because this one is particularly large, you have to be careful your way across the ocean as it could endanger sea traffic.
The event took place between July 10 and July 13, according to researchers who monitor the growing gap in the West Antarctic banana for years.
Iceberg, probably called A68, weighs more than a trillion tons. Its volume is twice as large as Lake Erie, one of the Great Lakes.
The final advance of the fault has been detected in NASA MODIS MODIS instrument data, images contained in thermal infrared at a resolution of one kilometer and confirmed by the VIIRS Suomi NASA instrument.
The development of the fault over the past year has been monitored with data from Sentinel-1 satellite of the European Space Agency – part of the European Copernican space component.
Sentinel-1 is a radar imaging system capable of acquiring images regardless of cloud cover and during the current winter polar darkness.
The iceberg weighs more than a trillion tons, but was already floating before dressing, which does not have an immediate impact on sea level.
