Beneath the ocean surface, a global mission is underway that could reshape our understanding of our planet. Inspired by Sir ...

Global full-depth ocean heat content (OHC) gain since 1960 reached a record 452 ± 77 ZJ in 2024. OHC was 15 ± 9 ZJ higher than in 2023, primarily associated with warming in the Atlantic and ...

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ...

New research challenges the long-held belief that the Arctic Ocean was covered by a massive ice shelf during ice ages.

Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the ...

For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor, paired ...

Even during the coldest 750,000 years, the Arctic Ocean had open water and sustained life thanks to seasonal sea ice. “Our ...

Parts of the Arctic are frequently free of sea ice in summer, although many shipping lines prefer to use “ice-class” vessels with extra-strong hulls. Many rely on Russian icebreakers, provided ...

Russia, which claims sovereignty over much of the Arctic Ocean, is reopening and modernising its Soviet-era bases on the coast. China, which has declared itself a “near-Arctic” state, is ...

“Transport of mercury from major sources like China to Greenland via ocean currents can take up to 150 years,” Dietz said. “This helps explain the lack of decline in Arctic mercury levels.” ...

The Netherlands could face winters up to 3° colder on average — and as much as 15° colder during severe cold snaps — if a key ocean current in the Atlantic collapses, according to new research ...
