  1. Inside Arctic ice lies a frozen rainforest of microorganisms

    Vast Arctic landscapes may appear to be desolate, barren places, but take a look through a microscope and you'll see thriving ecosystems. The top few meters of ice are home to an estimated hundred million billion trillion (or 10 to the power of 29) microorganisms. That's why Joseph...

  2. Call for Arctic Data Center Working Group Proposals

    The Arctic Data Center, in collaboration with the National Center for Ecological Analysis and Synthesis (NCEAS), announces a call for working group proposals. Funding for one working group will be available over a one- to one and half-year period beginning in August 2017. The Arctic Data...

  3. Solving the mystery of the Arctic's green ice

    In 2011, researchers observed something that should be impossible—a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. So, how was this bloom possible? Using mathematical...

  4. New MEaSUREs Greenland DEM Available at NSIDC DAAC

    The MEaSUREs Greenland Ice Mapping Project (GIMP) Digital Elevation Model from GeoEye and WorldView Imagery data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, part of the Making Earth System Data Records for Use...

  5. 7,000 underground gas bubbles poised to 'explode' in Arctic

    Scientists have discovered as many as 7,000 gas-filled 'bubbles' expected to explode in Actic regions of Siberia after an exercise involving field expeditions and satellite surveillance, TASS reported. A number of large craters - seen on our images here - have appeared on the...

  6. Up to half of the Arctic’s melt might be totally natural

    Scientists have known for a while that the Arctic is melting. The signs are everywhere—from the famed Alaskan Iditarod course being moved multiple times due to lack of snow, to the emergence of starving polar bears with nowhere to hunt. But while scientists are certain that the Arctic...

  7. Geosciences Special Issue "Cryosphere"

    A Special Issue, “Cryosphere”, of Geosciences aims to present the diversity within the field and state-of-the-art research on paleo-glaciations, glaciers, ice sheets, permafrost, sea ice, and snow cover. It also seeks to display a wide range of regional studies and methodological...

  8. NASA's aerial survey of polar ice expands its Arctic reach

    For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable data on how polar ice is changing in a warming world. Now, for the...

  9. Call for submissions: APECS International Polar Week 2017

    The Association of Polar Early Career Scientists (APECS) announces calls for submissions for events occurring during their International Polar Week Spring 2017. International Polar Week will take place 20-26 March 2017. Polar Week is a series of international events with the goal of promoting...
