NASA | Operation IceBridge: Greenland, Spring 2010


[Music] [Music] [Music] NASA’s Operation IceBridge Mission the largest airborne survey of adverse polar ice every flown kicks off it’s second year with the arrival of two NASA aircraft next week in Greenland. The team will spend 200 hours gathering data using a suite of instruments that peer below some of the regions critical glaciers IceBridge is aptly named because it will bridge the data gap between IceBridge is aptly named because it will bridge the data gap between the loss of NASA’s Ice Cloud and Land elevation satellite, or ICESat and the launch of ICESat 2 planned for 2015. [John Sonntag] I think its probably safe to say if it weren’t for Operation IceBridge or the similar efforts that the global science community would lose a lot of its knowledge of what’s going on with Greenland and Antarctica as a whole. [Narrator] 200 hours in the air, require a lot of work on the ground engineers have been outfitting NASA’s DC8 and PB3 aircraft with an array of science instruments. IceBridge planes resurvey previous ICESat tracks to get a sense of how arctic ice is changing. [John Sonntag] I think the last thing that NASA would like to see is to take a snap shot of the ice at the end of ICESat 1 operational period. Get another snap shot at the beginning of ICESat 2 and have no idea what happen in between. That is essentially what IceBridge is about is filling in that gap knowledge. [Bryan Blair] If you want to look at areas that are very dynamic like a glacial region its like a lot of ice moving through and there is a lot of vertical changes, we can map that entire area and capture the full spacial variably of that change. Which is a really good indication of what’s the mechanics of how that change is happening. [John Sonntag] Greenland because of it’s presence and Antarctica all the ice mass act as a buffer and climate and so if they were to start to melt, which many people believe that they are. Then the eventual affect will be a warmer climate over all. [Narrator] Annual spring missions over the arctic and fall missions over Antarctica will allow scientists to track changes in polar ice thickness and extent, so we have a better picture of ice dynamics. and future sea level rise. beep, beep, beep beep, beep, beep [end]

    that map looks incredible!

    Way to cover the down-time!!

    Officer: "Sir, there seems to be a problem"
    Commander: "What's that, son?"
    Officer: "Sir, a large chunk of ice has separated from Antartica. It looks like a large…"
    Salesman: "Hot dog! Who wants big hot dog?!"

    why do so many retards waste so much effort writing ignorant bullshit about phenomena they don't know anything about and only listen to fundamentalist christian right wing conservative fucknuts?

    With all respect to the Icebridge team, it's really strange and sad that this is needed. Imagine we'd lose satellite coverage of Iran, Afghanistan of Northern Korea for two weeks… The press would be all over it and Obama would have a hard time. Here we lose satellite coverage over BOTH arctic areas for half a decade in the midst of the greatest climate debate ever. And I assure you that the climate can effect us in a way that can make a bunch a moslem extremists a joke!

    The name of the new country will be: "Grashniaboffsky Land".
