With the coronavirus lockdown forcing us to spend more time isolated, or indoors with families or friends, what happens when people are forced to live in isolation for a whole year? We asked Beth Healey, researching the effects of physical and psychological isolation on a group of 13 crew members for the European Space Agency, how people change when totally isolated. #isolation #europeanspaceagency #antarctica

They were first women to overwinter in the Arctic Circle without a man. Now Sunniva Sorby and Hilde Fålulm Strøm face a longer stay due to the pandemic.

Now dozens of scientists are waiting in quarantine for the all-clear to join a year-long Arctic research mission aimed at improving the models used for forecasting climate change, just as the expedition reaches a crucial phase. News of the pandemic caused jitters among those already on board, said Matthew Shupe, an atmospheric scientist at the University of Colorado and co-leader of the MOSAiC expedition. The rest of the crew will be exchanged with the help of two other German research ships that will meet the Polarstern on the sea ice edge.

For a while, the international mission looked like it might have to be called off, as country after country went into lockdown because of the virus, scuppering plans to bring fresh supplies and crew to the German research vessel Polarstern that's been moored in the high Arctic since last year.

A new study shows that the West Antarctic Peninsula is experiencing some of the most rapid climate change on Earth, featuring dramatic increases in temperatures, retreats in glaciers and declines in sea ice. The Southern Ocean absorbs nearly half of the carbon dioxide -- the key greenhouse gas linked to climate change -- that is absorbed by all the world's oceans. The study tapped an unprecedented 25 years of oceanographic measurements in the Southern Ocean and highlights the need for more monitoring in the region. The research revealed that carbon dioxide absorption by surface waters off the West Antarctic Peninsula is linked to the stability of the upper ocean, along with the amount and type of algae present. A stable upper ocean provides algae with ideal growing conditions. During photosynthesis, algae remove carbon dioxide from the surface ocean, which in turn draws carbon dioxide out of the atmosphere. From 1993 to 2017, changes in sea ice dynamics off the West Antarctic Peninsula stabilized the upper ocean, resulting in greater algal concentrations and a shift in the mix of algal species. That's led to a nearly five-fold increase in carbon dioxide absorption during the summertime. The research also found a strong north-south difference in the trend of carbon dioxide absorption. The southern portion of the peninsula, which to date has been less impacted by climate change, experienced the most dramatic increase in carbon dioxide absorption, demonstrating the poleward progression of climate change in the region.

The U.S. lacks icebreaking capability in the Arctic and Antarctic and should build four polar icebreakers with heavy icebreaking capability to help minimize the life-cycle costs of icebreaker acquisition and operations, says a new congressionally mandated letter report from the National Academies of Sciences, Engineering, and Medicine.

Joint statements from the national science academies of the G7 nations were released today in advance of the G7 Summit to be held in La Malbaie, Canada, on June 8 and 9, 2018.

A new study has investigated the impacts of human activity on Antarctic Marine and Coastal. Alongside local effects of fishing, pollution and invasive alien species, global climate change is causing sea temperature rises and ocean acidification. Action is therefore needed at all levels to address these impacts.

Levels of air pollution significantly increase on the island of Svalbard in the Norwegian Arctic when tourist cruise ships are present, according to a recent study. With shipping levels rising in the region, the researchers recommend that stricter emissions regulations are introduced in order to limit the impact of pollution on the Arctic environment.

Reindeer herding has a long history in the Arctic, but climate change and industrial activity are bringing this important economic and cultural tradition to breaking point. In a unique initiative, reindeer herders across the Arctic are leading an international team of scientists in using modern technology to adapt to global change and empower indigenous communities.

The Arctic region is home to many unique, diverse and vulnerable ecosystems. But the once pristine Arctic environment is being increasingly affected by human activities. This thematic issue presents the latest research into the impacts of climate change and resource extraction on Arctic biodiversity and indigenous communities.

The rapid decline of Arctic sea ice has had dramatic effects on seals, polar bears, whales and other marine mammals. Changes in distribution, body condition, reproduction and abundance are all consequences of reduced sea ice that may escalate over the coming decade, according to a recent analysis.

For thousands of years, vast amounts of methane – a potent greenhouse gas – have been stored in frozen deposits on land and under the ocean in the Arctic. A new study has found that rapidly rising temperatures are accelerating the release of methane by thawing subsea ‘permafrost’, releasing nearly 8 million tonnes into the atmosphere each year and potentially increasing global warming.

New research on climate-driven reductions in Arctic sea ice has predicted that, by 2040 to 2059, new shipping routes will become passable across the Arctic, linking the Atlantic and Pacific oceans. An increase in traffic has implications for the ecosystems of this fragile area.

The largest ice sheet in the world, the east Antarctic ice sheet, may succumb to climate change faster than thought, according to recent research. Warming ocean currents, triggered by shifting wind patterns, could accelerate melting of the ice sheet, leading to a rise in sea levels, say the researchers.

Recent research reveals that even remote areas of the oceans are affected by increasing levels of plastic waste on the seafloor. The study found that quantities of litter from human activities, mostly plastic, on the seabed of an isolated Arctic site doubled from 2002 to 2011.

A recent study has considered 21st century changes in shipping access through the Arctic Ocean along three potential new routes linking the Atlantic and Pacific Oceans. As the sea ice melts, it is possible that high-strength vessels will be able to sail directly through the North Pole by the end of the century, its results indicate.

The rapid loss of Arctic sea ice affects not only animals that live on the ice but also microbial communities that live within the ice. A recent study discusses how microbes are affected by climate change, in some cases providing an early warning of major environmental shifts but in other cases amplifying them.
