  1. 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...

  2. 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...

  3. 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...

  4. NASA study improves forecasts of summer Arctic sea ice

    The Arctic has been losing sea ice over the past several decades as Earth warms. However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt...

  5. SETSM DEM processing software open source release

    We are pleased to announce the open source release of Surface Extraction from TIN-based Searchspace Minimization (SETSM) software. https://github.com/setsmdeveloper/SETSM https://mjremotesensing.wordpress.com/setsm/ SETSM provides fully-automated, user-friendly stereoscopic Digital Elevation...

  6. Call for Proposals - Arctic Data Center

    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...

  7. GoLIVE Data Set and Map Application

    The National Snow and Ice Data Center is pleased to announce the release of a new data set, “Global Land Ice Velocity Extraction from Landsat 8 (GoLIVE)”. GoLIVE is a NASA-funded effort that serves as a processing and staging system for near-real-time global ice velocity data...

  8. Groundbreaking arctic drone to test at Oregon's UAS range

    Prior to its scheduled launch in 2018, the ArcticShark—a groundbreaking new unmanned aerial system designed to collect the world’s most sophisticated atmospheric data in the Arctic—will undergo flight testing at Pendleton UAS Test Range starting today. To be owned by the...

  9. Air pollution may have masked mid-20th Century sea ice loss

    Scientists have observed Arctic sea ice loss since the mid-1970s and some climate model simulations have shown the region was losing sea ice as far back as 1950. In a new study, recently recovered Russian observations show an increase in sea ice from 1950 to 1975 as large as the subsequent...

  10. 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...

  11. 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,...

  12. 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...
