    OLYMPEX Scientists in the Field

    This video may not be very exciting for some… but our home planet deserves a mention once in a while. Joe Zagrodnik is a student at the University of Washington who is working with NASA scientists to measure the properties of rain and snow in the Olympic National Park. From November 10 through December 21, NASA and university scientists are taking to the field to study wet winter weather near Seattle, Washington. With weather radars, weather balloons, specialized ground instruments, […]

  • Widely Used Coolants Contribute to Ozone Depletion

    Widely Used Coolants Contribute to Ozone Depletion

    According to a new NASA study, a class of widely used chemical coolants known as hydro-fluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption.

    GPM Gets a Ton of Kilo

    GPM Gets a Ton of Kilo The Global Precipitation Measurement (GPM) mission core satellite provided many views of Tropical Cyclone over its very long life. GPM is a satellite co-managed by NASA and the Japan Aerospace Exploration Agency that has the ability to analyze rainfall and cloud heights. GPM was able to provide data on Kilo over its 21 day life-span. Enjoy and share…..     Celestron 21041 60mm PowerSeeker Telescope Old Price: $69.95 Price: $40.91

  • IceBridge Flies High over Both Poles

    IceBridge Flies High over Both Poles

    For the first time NASA’s Operation IceBridge is flying simultaneous missions over both the Arctic and Antarctic, on smaller, faster aircraft. These campaigns and aircraft represent both a unique opportunity for measuring polar ice, and something of a scientific trade-off from IceBridge’s traditional campaigns. Enjoy and share……

  • What Are Scientists Seeing Over Greenland?

    What Are Scientists Seeing Over Greenland?

    Why are scientists out flying over Greenland, drilling into its ice, and monitoring it from space? The answer is that they see it as a bellwether of future Earth. Scientists are sampling, drilling, and flying over this great island because they believe it may be a bellwether of future Earth. Greenland is two million square kilometers of land… 81% of which is covered by a giant central ice cap, the Inland Ice. Here is 2.8 million cubic kilometers of ice… […]

  • Interview with Tom Wagner

    Interview with Tom Wagner

    Sea Level Rising Hear from NASA scientists about the latest research on rising sea levels and melting polar ice. See surprising new views of ice loss in Greenland and Antarctica, and talk about the consequences of our rising oceans. Earth’s rising seas are some of most visible signs of our warming planet. Over the last 20 years, NASA satellites, airborne missions and field campaigns show a steady rise in global sea levels as the world’s polar ice sheets melt. As […]

  • Lakes On A Glacier

    Lakes On A Glacier

    How deep is that icy blue water on Greenland’s ice sheet? Dr. Allen Pope, of the National Snow and Ice Data Center, is using data from the NASA/USGS Landsat 8 satellite to find out. In this video, Dr. Pope shares what he sees when he looks at a Landsat image of the Greenland ice sheet just south of the Jakobshavn Glacier. Because the lakes are darker than the ice around them, they absorb more energy from the sun. A little […]

  • Scientists Link Earlier Melting Of Snow To Dark Aerosols

    Scientists Link Earlier Melting Of Snow To Dark Aerosols

    Tiny particles suspended in the air, known as aerosols, can darken snow and ice causing it to absorb more of the sun’s energy. But until recently, scientists rarely considered the effect of all three major types of light-absorbing aerosols together in climate models. In a new study, NASA scientists used a climate model to examine the impact of this snow-darkening phenomenon on Northern Hemisphere snowpacks, including how it affects snow amount and heating on the ground in spring. The study […]

  • The Helheim Experience

    The Helheim Experience

    Operation IceBridge has wrapped up its 2015 Arctic field campaign after covering a vast expanse of science targets during 33 different flights over land ice, sea ice, and glaciers. For more on the mission and the science it produces, visit nasa.gov/icebridge. And then take a few minutes to sit back, put on your headphones, go full screen, and enjoy a birds-eye view of a vast expanse of Greenland’s mountainous region near Helheim Glacier in eastern Greenland aboard a NASA C-130.

  • Antarctica’s Larsen B Ice Shelf Nearing Its Final Act

    Antarctica’s Larsen B Ice Shelf Nearing Its Final Act

    A new NASA study finds the last remaining section of Antarctica’s Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of the decade. Khazendar’s team used data on ice surface elevations and bedrock depths from instrumented aircraft participating in NASA’s Operation IceBridge, a multiyear airborne survey campaign that provides unprecedented documentation annually of Antarctica’s glaciers, ice shelves and ice sheets. Data on flow speeds came from spaceborne synthetic aperture […]
