A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater near the surface could help explain some of the decrease in Antarctic sea ...

The NSIDC said the measurement of sea ice taken Saturday, March 22, 2025, was 5.53 million square miles — around 30,000 square miles smaller than the lowest previous peak, set in 2017.

When attached to a drone, researchers can accurately measure sea ice depth — a measurement that’s challenging to get, and that informs scientists about the impacts of climate change.

While satellites have revolutionized our ability to measure sea level with remarkable precision, their data becomes less ...

The extent of sea ice isn’t the only measurement scientists are tracking. The thickness of the ice also matters and, since the 1980s, Arctic sea ice has become thinner.

Finally, we can measure the thickness of Arctic sea ice all year round, supporting ship traffic, weather and climate forecasts. The international study, led by researchers at UiT The Arctic ...

The NSIDC said the measurement of sea ice taken Saturday, March 22, 2025, was 5.53 million square miles — around 30,000 square miles smaller than the lowest previous peak, set in 2017.

Using satellite measurements of cloud cover and the solar radiation reflected by sea ice between 1980 and 2023, the researchers found that the percent decrease in sea ice's cooling power is about ...

Antarctic sea ice is now nearly 9% below normal. But the dramatic decline is not universal around the continent, which makes it difficult to predict the overall impact of climate change.

Melting Antarctic ice contributes to global sea-level rise, so a reversal of melting will slow that down. Understanding the dynamics of ice mass on Antarctica is thus essential.
