At the top of the planet, the cap of sea ice across Arctic waters grows and shrinks with the seasons, usually reaching its annual maximum extent in March. In 2026, this peak

, when the extent reached 14.29 million square kilometers, matching the lowest maximum observed since satellite monitoring began in 1979. One of the key areas contributing to the low maximum this year was the Barents Sea.

The Barents Sea lies at the periphery of the Arctic Ocean, bordered to the northwest by the Norwegian archipelago of Svalbard, and to the northeast and east by the Russian islands of Franz Josef Land and Novaya Zemlya, respectively. It is one of

—including the Central Arctic Ocean and nearby seas, bays, and waterways—across which scientists use remote sensing to track sea ice. The region is important for fisheries, shipping routes, and scientific research.

On March 17, 2026, the

satellite captured this image of the northern Barents Sea. Near Franz Josef Land, broken sea ice drifted near areas of open water closer to Novaya Zemlya. The region is often cloudy, as it was that day, but most clouds were thin enough to reveal the sea ice and water below.

In addition to the low extent, data from NASA’s

satellite indicate that Barents sea ice in mid-March 2026 was also very thin, according to Nathan Kurtz, chief of the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center.

Previous years, such as 2021 and 2025, also saw especially thin ice around the time of the maximum. “What was striking this year, however, was that the ice was also completely melted away in more of the Barents Sea, in addition to areas of thinning spreading northward,” Kurtz said.

On the opposite side of the Arctic, the Sea of Okhotsk also contributed to the low total sea ice extent across the Arctic in March 2026. But the factors driving the losses differ between the two regions.

In the Barents,

that the main driver is large-scale atmospheric circulation, with winds channeling warm, humid air from the North Atlantic straight into the area, accelerating melt. These winds can be influenced by tropical weather thousands of miles away. Disturbances originating over the Maritime Continent near Indonesia can “send ripples through the atmosphere that reach the Arctic within one to two weeks,” Kurtz said.

In contrast, the

mostly has thin, seasonal ice that changes thickness from year to year. Local winds play a big role, sometimes pushing the ice together to create thicker, ridged areas, and other times spreading it out, making it thinner. Because of this, the ice loss there is mainly driven by local weather, unlike in the Barents Sea, where distant atmospheric forces have a greater impact.
