Over the next century, the Arctic will change and look much different than it does today. Just how different is still unknown.
Arctic Ocean
Air-Ice-Ocean Coupling Observed in an Arctic Cyclone Event
New observations show detailed features of the ice-ocean response to a strong Arctic cyclone in the winter of 2019-2020.
The Many Adventures of Nitrogen in the Arctic Ocean
New research reviews how our atmosphere’s most abundant element cycles through the Arctic Ocean—and how climate change could affect the process.
Radioactive Isotopes Trace Hidden Arctic Currents
Tracing anthropogenic radionuclides shows researchers how water from the Atlantic flows into and mingles with Arctic currents.
The JOIDES Resolution Embarks on Its Final Expedition
On the ship’s last cruise, scientists will collect data to help predict future effects of climate change.
How Did We Miss 20% of Greenland’s Ice Loss?
The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.
Glaciers Rise and Fall—and Melt—with Tides
The effect of ocean water creeping beneath Greenland ice is stronger than scientists realized.
Protecting the Ozone Layer Is Delaying Arctic Melting
The Montreal Protocol has unintentionally slowed global warming and pushed back the first ice-free Arctic summer by 15 years, according to new research.
The Bering Land Bridge Formed Much Later Than Previously Thought
New research reconstructs the Bering Strait’s flooding history, raising surprising questions about human migration and how ice sheets form.
Underwater Sounds Help Reveal Extent of Glacial Calving
If a glacier calves into the Arctic Ocean, does it make a sound? Some scientists say yes and have devised a clever way to use those sounds to calculate the size of the fallen ice chunks.
