Iceberg B-46 is a large iceberg that broke free from Pine Island Glacier in Antarctica in October 2018. It was 225sq km at its greatest extent.[1] The iceberg was detected by the Landsat 8 satellite and later photographed by a NASA DC-8 as part of their IceBridge recording project.[1]

The shedding of icebergs by the Pine Island Glacier used to occur on average every 6 years; but has become a near annual event.[2]
