Iceberg A23a Grounded Near South Georgia Island - Earthdata
Mar 4, 2025 · Iceberg A23A was captured in this false-color corrected reflectance (Bands 7-2-1) image from the Moderate Resolution Imaging Spectroradiometer 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
Oct 22, 2024 · The animation starts with the massive iceberg (approximately 1,500 square miles in area, or about the size of the U.S. state of Rhode Island) just to the right of center. During the animation (November 12, 2023, to February 27, 2024), the iceberg slowly drifts left toward the center of the image, then moves toward the top of the image.
Iceberg A23A Moving Toward South Georgia Island, Antarctica
Jan 14, 2025 · The iceberg, or megaberg, could collide with the island or get stuck in the shoals around it, or the ocean currents could guide the iceberg around the island. Visit Worldview to visualize near real-time imagery from NASA's ESDIS; …
Glacier Power: What is Glacial Calving? | NASA Earthdata
Apr 11, 2025 · The iceberg ripped a 90 meter hole (approximately the size of a football field) in the ship, causing it to sink. More than 1,500 people died in the accident. Icebergs calved from tidewater glaciers are still a danger today. An iceberg over 80 kilometers long and 40 kilometers wide recently broke off from the Larsen Sea Shelf in Antarctica.
Swirling Iceberg A76A in the Drake Passage | NASA Earthdata
Dec 6, 2022 · A76A was part of the A76 iceberg that calved from the Ronne Ice Shelf in Antarctica in May 2021. These images were acquired by the Visible Infrared Imaging Radiometer Suite ( VIIRS ), aboard the joint NASA/NOAA Suomi National Polar orbiting Partnership ( …
Iceberg A76A calves from the Ronne Ice Shelf, Antarctica
Jun 2, 2021 · The A76 iceberg was initially approximately 4320 square km and has now broken into three icebergs, A76A, A76B and A76C. A76A is approximately 3500 square km, A76B is 480 square km, and A76C is 360 square km.

Glacier Power: Why is Glacier Ice Blue? | NASA Earthdata
Apr 11, 2025 · 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!
After the Larsen B | NASA Earthdata
Dec 27, 2020 · MacAyeal and his colleagues discovered the effect of these waves after an iceberg they were studying, named B-15A, abruptly shattered on October 27, 2005. B-15A was a large iceberg, about the size of Luxembourg, which had run aground off of the coast of Antarctica. It broke up on a calm day with locally mild weather, puzzling observers.
