Cracks in Arctic sea ice turn low clouds on and off
The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds. (2020-01-10)

Arctic sea ice diminished rapidly in 2004 and 2005
The Arctic Ocean's perennial sea ice shrank abruptly by 14 percent between 2004 and 2005, according to a newly published study. The loss of perennial ice in the East Arctic Ocean, above Europe and Asia, neared 50 percent during that time, as some of the ice moved to the West Arctic Ocean, above North America. The overall decrease in winter Arctic perennial sea ice equaled the area of Texas. (2006-09-13)

Scientists find the error source of a sea-ice model varies with the season
Scientists evaluated the sea-ice simulations of the Arctic regional ocean-ice coupling configuration of the Massachusetts Institute of Technology general circulation model (MITgcm) and found there were disagreements between the simulations and observations in both March and September. (2020-12-30)

'Archived' heat has reached deep into the Arctic interior, researchers say
Arctic sea ice isn't just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic. (2018-08-29)

Arctic current flowed under deep freeze of last ice age, study says
During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even stopped. But in a new study in Nature, researchers show that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times. (2013-05-29)

Scientists with Pohang University of Science and Technology (POSTECH), Max Planck Institute for Meteorology, and Korea Institute of Ocean Science and Technology, presented on Monday, April 20, in Proceedings of National Academy of Sciences online, the geophysical impact of phytoplankton that triggers positive feedback in the Arctic warming when the warming-induced melting of sea ice stimulates phytoplankton growth. The paper is titled 'Amplified Arctic warming by phytoplankton under greenhouse warming.' (2015-04-21)

Scientists expand understanding of how river carbon impacts the Arctic Ocean
Arctic rivers transport huge quantities of dissolved organic carbon to the Arctic Ocean. The prevailing paradigm regarding DOC in arctic rivers is that it is largely refractory, making it of little significance for the Arctic Ocean biogeochemistry. However, a recent study shows that DOC in Alaskan arctic rivers is remarkably labile during the spring flood period when the majority of annual DOC flux occurs. The research was published Feb. 9 in Geophysical Research Letters. (2008-02-12)

Influence of sea-ice loss on Arctic warming is shaped by temperatures in the Pacific Ocean

Materials from arctic shelves are changing the water's composition
Scientists say the input of shelf-derived materials to the central Arctic Ocean over the past decade appears to be increasing. They further note that this increase is altering the water's composition and could threaten biological productivity and species assemblages. Their results provide one of the first. (2018-01-03)

Melting tundra creating vast river of waste into Arctic Ocean
The increase in temperature in the Arctic has already caused the sea-ice there to melt. According to research conducted by the University of Gothenburg, Sweden, if the Arctic tundra also melts, vast amounts of organic material will be carried by the rivers straight into the Arctic Ocean, resulting in additional emissions of carbon dioxide. (2010-01-11)

Arctic expeditions find giant mud waves, glacier tracks
Scientists gathering evidence of ancient ice sheets uncovered a new mystery about what's happening on the Arctic sea floor today. Sonar images revealed that, in some places, ocean currents have driven the mud along the Arctic Ocean bottom into piles, with some (2007-12-12)

The Arctic and global warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. That's the word from University of Miami Rosenstiel School's Dr. Sharon Smith who will speak on today at 3 p.m. HST (8 p.m. EST) in Honolulu at the American Geophysical Union's 2006 Ocean Sciences Meeting. (2006-02-20)

Climate change could release old carbon locked in Arctic soils, researchers say
Scientists have been able to determine the approximate age of dissolved organic carbon in the Arctic for the first time. Most of the carbon that reaches the ocean is relatively young at present, but this could change. Warming of the Arctic could affect northern peats, collectively one of the largest reservoirs of organic carbon on Earth. As the carbon-rich soils warm, the carbon is more susceptible to being transported to the ocean by rivers small and large. (2004-03-02)

Arctic Ocean acidification worse than previously expected
Arctic Ocean acidification worse than previously expected. (2020-06-17)

Scientists zero in on Arctic, hemisphere-wide climate swings
In the late 1990s, as scientists were reaching consensus that the Arctic had gone through 30 years of significant climate change, they began reading the first published papers about the Arctic Oscillation, a phenomenon reported to have hemisphere-wide effects. Since then scientists have learned more about the dynamics of post-glacial arctic climate change than in the 50 previous years, says Richard Moritz of the University of Washington's Applied Physics Laboratory. (2002-08-29)

Unraveling a major cause of sea ice retreat in the Arctic Ocean
Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean. (2017-09-06)

Is the ice in the Arctic Ocean getting thinner and thinner?
The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists at the Alfred Wegener Institute are concerned about the long-term equilibrium in the Arctic Ocean. (2010-08-20)

Arctic could be iceless in September if temps increase 2 degrees
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati. The study by an international team of researchers was published in Nature Communications. (2019-08-13)

Less ice, more water in Arctic Ocean by 2050s
