The Arctic Ocean (Figure 1), the smallest of the world's five major oceans, is about 4000km (2500 miles) long and 2400km (1500 miles) wide, about the size of the continental USA. It lies entirely ...

To do the study, the research team used high-resolution climate models to better predict marine heatwaves, especially in the Arctic. The authors say that this allowed them to track ocean currents and ...

Scientists search the Arctic for answers. Why is an ocean current critical to world weather losing steam? Scientists search the Arctic for answers. West Antarctica is melting—and it’s our ...

Another concern among scientists is that melting sea-ice is affecting a major ocean current in the Arctic - the Beaufort Gyre. Freshwater is less dense than salty seawater. The researchers said a ...

What happens in the Arctic doesn't stay in the Arctic,' says a conservation lead and climate expert on the accelerated warmth ...

The Arctic Ocean is undergoing rapid changes ... supports marine ecosystems, and facilitates ocean currents that transport heat and nutrients around the globe. Additionally, sea ice reflects ...

Crucially, the clam data came from a spot on the border between the AMOC and Arctic waters, where ocean conditions are heavily dependent on the strength of currents flowing from the south.

They warn that this shift will have far-reaching effects beyond the polar regions, impacting weather patterns, ocean currents, and the global climate. "The first ice-free day in the Arctic won’t ...

Much less of the ocean is covered by ice ... “A lot of our current knowledge about the Arctic climate is based on their observations,” says sea-ice physicist Gunnar Spreen.

The Arctic Ice Project has put forward the idea ... building "free-floating" underwater sea walls that "block the warm ocean currents from melting the glacier from below" and mimicking the cooling ...
