NASA Satellite Imagery Reveals Antarctic Island Losing Snow Cover

Captured by the Landsat 9 satellite, images from March 2025 and October 2026 highlight a significant shift in the island’s surface composition. Where snow previously dominated the landscape, dark ice now prevails. Glaciologist Mauri Pelto of Nichols College attributes this trend to unusually high winter temperatures recorded in 2026, which stifled fresh snow accumulation.

Beyond rising temperatures, the island is suffering from the dual effects of sublimation—where ice turns directly into vapor—and persistent, high-velocity winds that strip away surface layers. This loss of snow cover creates a feedback loop: darker ice absorbs significantly more solar energy than reflective snow, accelerating the melting process as summer approaches. Pelto warns that the island’s iconic, skull-like features may soon distort as the Bahia del Diablo glacier recedes and the rocky formations wear away. While intermittent spring storms could provide temporary relief, the long-term trend remains clear, with bedrock exposure increasing across the region.
