  1. Melting sea ice may be speeding nature's clock in the Arctic

    Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the...

  2. POPs contamination in the Arctic declining, report finds

    A newly-released Arctic Council report on persistant organic pollutants contains some positive findings for the circumpolar world. POPs—which include toxic PCBs, DDT and dioxins—are produced mainly in industrial areas, but are carried by air and water currents into the Arctic,...

  3. Climate change, changing predator-prey habits in Arctic

    Researchers had thought this might happen. With the Arctic sea ice melting sooner, and forming later, and with decreasing ice extent, one of the world’s biggest predators, the killer whale, has been moving further into new areas, and for longer periods. What’s more is that it is...

  4. AMAP Assessment 2015 published

    AMAP Assessment 2015: "Temporal Trends In Persistent Organic Pollutants in the Arctic" has now been published. Find the electronic version at http://www.amap.no/documents/doc/AMAP-Assessment-2015-Temporal-Trends-in-Persistent-Organic-Pollutants-in-the-Arctic/1521. You are...

  5. Scientist at work: Tracking muskoxen in a warming Arctic

    Our Earth has unimaginable diversity, from seascapes 8,000 meters below the ocean’s surface to landscapes 8,000 meters above it. Its physical beauty comes in inconceivable living varieties. Some mammals lay eggs; some lizards are legless. Bats catch fish. Birds catch bats. Wood frogs in...

  6. Engineers help arctic ships assess ice buildup

    As global temperatures rise and arctic ice melts, more ships are taking advantage of expedient, yet dangerous ocean routes that are opening in the polar region. One of the main hazards of sailing in freezing temperatures is topside icing, in which water blown from the ocean freezes once it...

  7. Litter levels in the depths of the Arctic are on the rise

    The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research...

  8. Wind-Powered Pumps Could Make Arctic Ice

    Physicist Professor Steven Desch from Arizona State University has come up with an idea for combatting Arctic ice loss. He is proposing the installation of 10 million wind-powered pumps over the Arctic ice cap. In winter, these would be used to pump water to the surface of the ice where it...

  9. Resource Available - Arctic Research Plan 2017-2021, IARPC

    The Interagency Arctic Research Policy Committee (IARPC) announces the release of their Arctic Research Plan 2017-2021 and new IARPC collaboration teams that will implement this plan. Nine collaboration teams are now launching and are open to participation by anyone in the community. The...

  10. Salt concentrations in ice cores could unveil DO events' recipe

    It is one thing to know that Earth has already faced abrupt climate changes—also known as Dansgaard–Oeschger (DO) events—in the past. But finding out the reasons for these dramatic and rather short term changes is another story, one that Dr Rachael Rhodes from the University...
