- Icebergs - NASA Earthdata
NASA's iceberg data includes current and historical measurements useful for mapping icebergs, glaciers that calve them, and their characteristics
- Iceberg A23a in the Southern Ocean, Antarctica - Earthdata
Iceberg A23a calved from the Filchner–Ronne Ice Shelf (on the northwestern side of Antarctica) in 1986 and had been stuck in the Weddell Sea off the coast of West Antarctica until it started moving again in 2020
- Glacier Power: What is Glacial Calving? - NASA Earthdata
Glacier Power: What is Glacial Calving? When a piece of a glacier breaks off, it's called calving, and results in an iceberg
- Iceberg A23A Grounded Near South Georgia Island - Earthdata
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

- Antarctic Iceberg A23A Continues to Crumble | NASA Earthdata
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
- Glacier Power: Why is Glacier Ice Blue? - NASA Earthdata
Glacial ice is a different color from regular ice It is so blue because the dense ice of the glacier absorbs every other color of the spectrum except blue — so blue is what we see!
- Glacier Power: How do Glaciers Form? | NASA Earthdata
From Snowflakes to Rivers of Ice Glaciers are massive and incredibly powerful, but they begin with small snowflakes Imagine how many snowflakes make a glacier as snow gradually changes into glacier ice
