  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. 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,...

  9. 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...

  10. 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...

  11. 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...

  12. 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...
