The largest recorded iceberg Iceberg B-15 rivaled Connecticut in size when it calved from Antarctica?s Ross Ice Shelf in March 2000. Giant chunks eventually wandered into the Southern Ocean. Twelve years later it was gone. Ice shelves secure glaciers in place. Both birth icebergs as a natural process much like shedding dead skin cells but ice shelf calving does not add to sea level rise ...

 

NASA has data on sea ice glaciers snow cover and other frozen features that comprise Earth?s cryosphere and effect human activity and our planet.

 

Iceberg A23A calved from East Antarctica's Filchner?Ronne Ice Shelf in 1986. Forty years later it is finally disappearing and rapidly. This true-color corrected reflectance image captured on Jan. 13 2026 by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard the Aqua platform shows the iceberg melting turning blue and breaking apart in the South Atlantic between ...

 

NASA's true-color corrected reflectance image of a very large iceberg A23A moving toward South Georgia Island in Antarctica was captured by the MODIS instrument aboard the Terra satellite.

 

Iceberg A23A was captured in this false-color corrected reflectance (Bands 7-2-1) image from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua platform on March 4 2025. The iceberg the big blue object southwest of the island has run aground near South Georgia Island in Antarctica .

 

NASA's true-color corrected reflectance image of Iceberg A23A and iceberg A23F was captured on August 17 2025 from the MODIS instrument aboard the Aqua satellite.

 

An iceberg over 80 kilometers long and 40 kilometers wide recently broke off from the Larsen Sea Shelf in Antarctica. Many ships sail in this area so satellites monitor the area for any icebergs that may be in a ship?s path. There are also many glaciers in Glacier Bay Alaska--which is how it got its name.

 

Iceberg A23A calved from East Antarctica's Filchner?Ronne Ice Shelf in 1986 and had been stuck in the Weddell Sea off the coast of West Antarctica until it started moving again in 2020.

 

NASA's iceberg data includes current and historical measurements useful for mapping icebergs glaciers that calve them and their characteristics.
