      On May 8, 2023, the Moderate Resolution Imaging Spectroradiometer on   
      NASA's Aqua satellite acquired a true-color image of a new-born   
      iceberg. The long, thin berg, named Iceberg A-76D floats under cloud   
      cover and west of South Georgia Island. Both the berg and the island   
      appear to have similar shapes and size.   
      
      The narrow A-76D is the fourth piece to break off of an enormous   
      iceberg which calved from the western side of the Ronne Ice Shelf, in   
      the Weddell Sea in May 2021. At the time it calved, that iceberg   
      (called A-76) was estimated to span about 4,320 square kilometers   
      (1,668 square miles), which made it slightly larger than the Spanish   
      Island of Majorca. Within a month, the monster berg lost its claim to   
      be the largest iceberg on Earth when it broke into 3 large pieces.   
      
      The largest of those pieces, Iceberg A-76A has been drifting slowly   
      northward. It was spotted in the Drake Passage, about 2,000 km (1,200   
      miles) north of where it was calved, in October 2022. The Drake Passage   
      is a turbulent body of water between South America’s Cape Horn and   
      Antarctica’s South Shetland Islands. Icebergs often drift into the   
      Drake Passage, thanks to the powerful Antarctic Circumpolar Current   
      funneling into it, and then can whip northward toward the equator and   
      quickly melt in the warming waters.   
      
      In late April 2023, Iceberg A-76A was spotted drifting in the Northern   
      Weddell Sea, but it had broken apart to create a new-born berg. On   
      April 29 the U.S. National Ice Center (USNIC) confirmed that iceberg   
      A-76D calved from iceberg A-76A in the northern Weddell Sea. A report   
      of that calving, along with a MODIS image showing the freshly-split   
      sliver of A-76D along with the parent berg can be viewed  here.
