The Larsen C Iceberg will be Huge

1It’s the final countdown

The European Space Agency said on Wednesday that just three miles separate the Larsen C crack– a rift slicing the front off a major Antarctic ice shelf– from open water.

Like a tailor with a tape measure, scientists have been measuring the crack using ESA satellites. The next Sentinel-1 satellite pass will happen later this week, providing a high-resolution look at whether the Larsen C ice shelf has finally calved an iceberg.

While the Sentinel-1 satellite has provided the clearest view of the state of the crack, CryoSat, another ESA mission monitoring ice at both poles, has the ability to see through water and ice, providing the clearest understanding of the volume of the soon-to-be iceberg. Sentinal-1 only passes over Larsen C once every 6 days.
