The Arctic Ocean, once locked in a vault of thick, old ice, now is transforming at lightspeed. Temperatures there are increasing at up to four times the rate of the planet overall, melting sea ice ...

The Arctic is experiencing a steady rise in human-generated underwater noise as melting ice and increasing activity open the ...

As the Arctic Ocean loses its sea ice due to climate change, sunlight penetrates deeper into the water and encourages the growth of tiny plant-like organisms (phytoplankton). But to thrive, they need ...

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now, a new study published in Science Advances challenges this idea ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...

The loss of Arctic sea ice has long been a graphic measure of human-caused climate change, with wrenching images of suffering polar bears illustrating a worsening planetary crisis. Now, new research ...

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 ...

Led by the European Research Council Synergy Grant project Into the Blue – i2B, the research team studied sediment cores collected from the seafloor of the central Nordic Seas and Yermak Plateau, ...
