Scientists at the Australian Antarctic Partnership Program are just beginning to understand the dire effects of extremely low ...

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

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

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 ...

With climate change accelerating the loss of sea ice in Hudson Bay and the Arctic Ocean in general, the region is facing increased shipping activity, heightening the risk of oil spills.

When ice melts, the darker ocean water absorbs more heat, accelerating warming in the Arctic and beyond. It’s like replacing a mirror with a blackboard; the latter absorbs much more light and heat.

Emperor penguin populations are falling much faster than expected. Ice is melting beneath their chicks before they’re ready.

A breakthrough study has uncovered that the Southern Ocean's power to pull carbon dioxide from the atmosphere fluctuates dramatically depending on winter sea ice. When sea ice lingers longer ...
