The data, collected between August 2025 and January 2026, shows ice extent increasing by approximately 2.1 million square kilometers compared to the same period last year.
"We're observing ice thickness averaging 3.8 meters in key regions, which is significantly higher than our 2020-2024 baseline measurements," Peterson explained.
The expansion appears most pronounced in the Beaufort and Chukchi seas, where ice formation began earlier than typical seasonal patterns.
