NASA | Keeping a Close Eye on Jakobshavn

Jakobshavn Glacier, one of the fastest moving glaciers in Greenland, has been the focus of IceBridge survey flights for five consecutive years. Here, images from an IceBridge mission on Apr. 4, 2013 and video footage from the 2012 Arctic campaign show this rapidly changing ice stream and how IceBridge is using its suite of airborne instruments to collect crucial data on ice movement and how much glaciers like Jakobshavn might contribute to future sea level rise.

Bravo, thanks for this fascinating upload. It's amazing what can appreciated and better grasped, all in a well produced 2 min video.

Best of luck and success for these continued missions!

In fact, a big change occurs during these 37 years, the glacier moved faster than before! and that's why the terminus is at the same place in 2001 compared with 1964 (but it didn't really stay like that during this time)

[Spartan]

Yes, that's true. That just shows us how we effect our surroundings

[msfpmm]

Any have any idea why 1964-2001 (37 years) the change seems minimal compared to other shorter time periods?

[jellisday]

Yeah, that's exactly what happens. The summer constellations are not the same as the winter constellations.

The city is called Ilulissat, not Jakobshavn

It is clear from NASA's own data here that the ice was melting long before the industrial revolution could have made any measurable difference, is it not?

[navidrasekhi]

I am worried about the future of earth. Ten years later the two polar ice caps how much distance?

Orbit

Put a light in the middle of the room. The light represents the sun. Put your back to the sun and face the east (night). What do you see? Know orbit to the west side again with your back to the sun. What do you see? Nothing you seen when you were at the east side. Get it?

[utubelesst]

Have you ever not seen the Big Dipper at night?

[utubelesst]

..

The sun is so big it takes up all view in its direction. Being on the other side would b very obvious even to people that only have book smart capabilities.

Book smart is- The enability to know more than someone writes!
B updateable!

Are you sure you see in winter the same stars as in summer? Think again...

[MrsLecter]

I'm so far north it seems they are always the same.

[utubelesst]

You would see a totally different sky.
