Iceberg theory education. Iceberg A23C is almost 20km in length and 8km in Glacier Power: What is Glacial Calving? When a piece of a glacier breaks off, it's called calving, and results in an iceberg. May 3, 2025 · Iceberg A23A, which grounded in early March, is the rectangular feature in the center of the image. Feb 27, 2024 · The embedded view above shows a series of false-color corrected reflectance images of iceberg A23a in the Southern Ocean, Antarctica. This before-and-after comparison shows Iceberg A23C breaking off Iceberg A23A between April 11 and April 12. Dec 4, 2022 · Animation starting November 20 and ending December 4, 2022, of Iceberg A76A swirling in the Drake Passage. Glacial ice is a different color from regular ice. A76A was part of the A76 iceberg that calved from the Ronne Ice Shelf in Antarctica in May 2021. Press "Play" in the lower left corner of the embedded map to watch iceberg A23a move through the Southern Ocean. . Iceberg A23C, which broke off in mid-April, can be seen on the right side of the image. The iceberg, the big blue object southwest of the island, has run aground near South Georgia Island in Antarctica . 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! NASA Worldview offers the capability to interactively browse over 1,200 global, full-resolution satellite imagery layers and download the underlying data. Jan 14, 2025 · 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. Mar 4, 2025 · 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. NASA's iceberg data includes current and historical measurements useful for mapping icebergs, glaciers that calve them, and their characteristics.
