- 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 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
- Iceberg A23a in the Southern Ocean, Antarctica - Earthdata
The embedded view above shows a series of false-color corrected reflectance images of iceberg A23a in the Southern Ocean, Antarctica Press "Play" in the lower left corner of the embedded map to watch iceberg A23a move through the Southern Ocean
- Glacier Power: What is Glacial Calving? - NASA Earthdata
When a piece of a glacier breaks off, it's called calving, and results in an iceberg
- Iceberg A23A Sheds a Piece - NASA Earthdata
Iceberg A23A, which grounded in early March, is the rectangular feature in the center of the image Iceberg A23C, which broke off in mid-April, can be seen on the right side of the image This before-and-after comparison shows Iceberg A23C breaking off Iceberg A23A between April 11 and April 12 Iceberg A23C is almost 20km in length and 8km in
- 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! It’s Not Just Frozen Water Sometimes the glacial ice appears almost turquoise Its crystalline structure strongly scatters blue light The ice on a glacier has been there for a really long time and has been
- Iceberg A23A Moving Toward South Georgia Island, Antarctica
The animation above shows a series of true-color corrected reflectance images from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard the Terra platform of Iceberg A23A moving toward South Georgia Island in Antarctica Press the "Play" button in the lower left corner to view the animation spanning the dates December 14, 2024, to January 30, 2025 A23A is currently the
- Iceberg A81 Calving from the Brunt Ice Shelf, Antarctica
The iceberg is approximately 1550 km 2, which is about twice the size of New York City Professor Dominic Hodgson, British Antarctic Survey glaciologist, states that the calving was expected, is part of the natural behavior of the Brunt Ice Shelf, and is not linked to climate change
