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
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 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!
Glacier Power: How do Glaciers Form? - NASA Earthdata 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
