Satellite imagery captured the world’s largest iceberg continuing to spin in the Southern Ocean near Antarctica throughout October.Footage released by the Cooperative Institute for Research in the Atmosphere at Colorado State and the National Oceanic and Atmospheric Administration (CSU/CIRA & NOAA) shows iceberg A23a, spinning in the Southern Ocean, north of the South Orkney Islands of Antarctica.According to a BBC news report, the iceberg has been captured on top of a huge rotating cylinder of water since April, spinning counter-clockwise about 15 degrees a day.A23a is approximately 1,500 square miles in area, the size of Rhode Island, according to the NOAA.As long as the iceberg is stuck on the vortex, according to NASA, it delays its path along “iceberg alley,” a current that takes icebergs north to warmer waters, where they rapidly melt.
