Satellite images show flooding in Kangerlussuaq, Greenland


Recent satellite images show flooding in Kangerlussuaq, a key air transportation hub on Greenland. Located in southwestern Greenland roughly 125 kilometers (75 miles) from the coast, Kangerlussuaq, or Kanger, hosts one of the island’s busiest commercial airports. Kangerlussuaq is a frequent departure point for scientific research flights, including the NASA IceBridge program.

Near the airport, the Watson River flows through town. The river is fed by the nearby Russell glacier, which sits just outside of town. Unlike other glaciers, which are exposed to the warming ocean waters, it sits entirely on land.

The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite observed the flooded river on July 12, 2012. River levels were discernible higher throughout the image; downstream from Kangerlussuaq, braided channels have merged into a single water body.

Having recently returned from a trip to Greenland, Jason Box of the Byrd Polar Research Center at Ohio State University noted an increase in the intensity of spring and summer melt over the past dozen years. Richard Forster, a University of Utah professor, said that water rises every year, but he have never before observed it at this level of discharge. The melting event was also about two weeks prior to the normal seasonal peak. He noticed that it was most likely due to melt on the ice sheet – rather than an ice-dammed lake bursting or glacial lake drainage – as the high discharge was maintained for so long.

Ted Scambos, lead scientist at the National Snow and Ice Data Center, points that even though melt water mostly refroze in place in the upper part of the Greenland Ice Sheet, lower down the melt runs off the ice sheet into rivers and creeks and into the ocean.

A bridge spans the river at a narrow point southeast of the airport, and allegedly dates from the 1950s. By July 21, flood waters had washed out parts of the bridge, according to video footage published by The Guardian.

  1. If you look further into this, this happens every year in Greenland. Also the airport out there is presently open at this time. So no flooding like it is showing here. Go to google and type in Kangerlussuaq airport and go to the airport link. I wish people would look further into the articles they dump on their websites… Before posting them.

    1. Sorry Sonia, but I dont understand where do you find this information in the article? Where it said that the airport is flooded? And this satellite images got dates that they were aquired, so go to datasearch with timelog, I’m sure that you’re find it.
      Kangerlussuaq is a settlement, not only an airport, and you can read it in this post as well. And title of post said “Flooding in Kangerlussuaq” and not “Flooding at Kangerlussuaq airport”. Do some semantics and watch the order in sentence.And tell me – what’s your point?
      Who said that this isn’t happening every year at Greenland? Why you so pissed?

      Please, let me know…
