  The US National Ice Center - naming Antarctic icebergs
  
  Icebergs are created when large chunks of freshwater ice break off Antarctic ice shelves or glaciers and calve into the Southern Ocean. To be classified as an iceberg, the ice extruding from the water must be at least five metres above sea level, be between 30-50 metres thick, and must cover an area of at least 500 square meters. Icebergs can have a direct effect on the sea bed, scouring the seafloor where it makes contact. But who monitors icebergs? And how big can they get? … read more »

Tides under Ronne-Filchner Ice Shelf move grounding line by 20km

One of the highest tidal ranges in Antarctica is 5 meters, but it occurs far from open water, beneath the Ronne-Filchner Ice Shelf. Where the Foundation Ice Stream meets the shelf, the grounding line is located 2km below sea level. With each tide, the grounding line oscillates 20km back and forth along the bedrock.
