Greenland’s jagged coastline is lined with fjords, many of them cradling marine-terminating glaciers that routinely calve icebergs into the water. It’s common to see these bergs, small and large, drifting in the island’s fjords each summer once the sea ice breaks up. In summer 2026, one exceptionally large berg turned up in the Denmark Strait—more than a thousand kilometers south of where it apparently originated.
These images, captured by the OLI (Operational Land Imager) on Landsat 9, show the iceberg on June 12 as it drifted in the strait between Greenland and Iceland. It was just south of Kangikajiip Appalia, a cape on Greenland’s east coast visible in the scene’s upper left, amid a mixture of sea ice and berg fragments known as “mélange.”
Alexis Denton, oceanographer and chief scientist with the International Ice Patrol, noted that several clues indicate it is an iceberg rather than thick, multi-year sea ice: its proximity to shore, its whiter color, and larger size compared to the surrounding sea ice. Measuring roughly 17 square kilometers (7 square miles) on June 12, the iceberg was about five times the area of New York City's Central Park. That’s modest compared to the behemoth bergs that calve from Antarctic glaciers and ice shelves but large by Greenland standards.
