Today’s Arctic is different in that there is a new player in the region, namely China, which is bringing new opportunities to the area, but at the same time making political and security issues there even more complex.

Two new papers offer radically different predictions of the glacier’s future — and thus for the future of low-lying cities around the world. Here’s how to understand the divergent projections

The Canadian Coast Guard announced on 6 May 2021 that two Polar icebreakers will join its fleet to enhance Canada’s Arctic presence and provide critical services to Canadians.

A team led by physical oceanographers at Scripps Institution of Oceanography at the University of California San Diego, and including Bangor University scientist, shows in a new study how plumes of warm water are flowing into the Arctic Ocean from the Pacific Ocean and accelerating sea ice melt from below.

By the end of 2020, nine of the ten countries-signatories ratified the 2018 Central Arctic Ocean Fisheries Agreement. But is that reason to celebrate? Not really…

Researchers discover sponge paths on the ocean floor

The 21st century serves as an inflection point of acceleration of climate instability caused by human-generated greenhouse gases, as CO2 emissions increase well beyond the rate of the prior century.

For decades, the frozen Arctic was little more than a footnote in global economic competition, but that’s changing as its ice melts with the warming climate.

New sea routes through the arctic threaten to increase emissions through maritime traffic.

While global headlines continue to focus on Russia’s “aggressive postures” against Ukraine, Moscow seems to be slowly and steadily playing its geopolitical game in the Arctic, by emphasizing the importance of the accessibility to Arctic ports and further developing the shipping lanes of the Northern Sea Route (NSR), connecting the Pacific and Atlantic.

Antarctica may seem far away for most of us, yet this remote continent contains enough ice to raise sea levels around the world by tens of metres. Its fate has important implications for coastal regions worldwide and the billions of people who live within them.

Maxim Kulinko, Deputy Director of Rosatom State Atomic Energy Corporation’s Northern Sea Route Directorate, talked with Arctic.ru correspondent Kristina Khramtsova and discussed ways to increase freight traffic volumes to 80 million metric tons by 2024. They also talked about measures to offer year-round navigation.

The U.S. Antarctic Program Data Center is providing new services to help scientists document, preserve, and disseminate their research and to facilitate reusability of a wide range of valuable data.

Data will contribute to updating ecosystem-based fishery management for the Southern Ocean

Living at depths approaching an entire mile, deep-sea Arctic sponges are a scientific curiosity, as they’ve somehow managed to make this extreme environment their home. New evidence gathered over the course of an entire year is taking biologists a step closer to understanding these ecologically important sponges and how they’re able to survive such harsh conditions.

Permafrost thaw is one of the world’s most pressing climate problems, already disrupting lifestyles, livelihoods, economies, and ecosystems in the north, and threatening to spill beyond the boundaries of the Arctic as our planet continues to warm.

Intensity of phytoplankton production during Antarctic summer affects the structure of seafloor ecosystems

After years of cracking and crumbling, a humongous iceberg finally broke away from Antarctica's Brunt Ice Shelf last month and began drifting out to sea. Like a retractable skylight, the event gave us a rare glimpse at a previously unreachable seafloor absolutely teeming with life.

The World Ocean covers approximately 361.1 million km2 (70.8%) of the Earth’s total surface. It is divided into five oceanic areas, separated by the different world continents. The Southern Ocean, also known as the Antarctic Ocean, is the fourth-largest ocean by surface area, spanning over 20.3 million km2.

Today the Arctic is one of the world’s key regions both economically and in terms of military security.

New study on submarine permafrost suggests locked greenhouse gases are emerging.

This is a transcript of episode 5 of The Conversation Weekly podcast, How climate change if flooding the Arctic Ocean with light. In this episode, two experts explain how melting ice in the far north is bringing more light to the Arctic Ocean and what this means for the species that live there. And we hear from a team of archaeologists on their new research in Tanzania’s Olduvai Gorge that found evidence of just how adaptable early humans were to the changing environment.

Permafrost thaw is one of the world’s most pressing climate problems, already disrupting lifestyles, livelihoods, economies, and ecosystems in the north, and threatening to spill beyond the boundaries of the Arctic as our planet continues to warm.

New research is causing scientists to rethink how polynyas—massive openings in the sea ice—are formed

A sheet of ice the size of the iconic lake on the New York-Vermont-Quebec border or the city of Los Angeles rapidly separated itself from the Brunt Ice Shelf on Antarctica last week.
