Across the globe, snow and ice play a vital role in regulating Earth’s climate and providing freshwater resources to people, plants, and animals.

As Earth’s frozen regions change rapidly, NSIDC is committed to growing its research and open access data to better understand these changes. Read about NSIDC research and its contribution to science and policy making. Check out spotlights on how to use NSIDC data, tools, and resources. Learn about how we steward data and collaborate with scientists and organizations across the world to understand how the frozen parts of Earth affect the rest of the planet and impact society.

The Antarctic Peninsula has had an intense melt season with above average melting persisting through much of February. Saturated snow from a high melt year and low sea ice in Bellingshausen Sea have led to a series of minor calving events on the Wilkins Ice Shelf. Elsewhere in Antarctica, melting was near average.
