Abstract: The ice motion map reveals various flow regimes, ranging from patterned enhanced flow into a few large glaciers in the cold, low precipitation areas of north Greenland; to diffuse, enhanced flow into numerous, narrow, fast-moving glaciers in the warmer, high precipitation sectors of northwest and southeast Greenland. We find that the 100 fastest glaciers (v > 800 m/yr) drain 66% of the ice sheet in area, marine-terminating ...-> continue reading
Greenland's melting is real: It is visible from space and from the ground. Radar reflectivity shows the signature of water instead of ice, temperatures went above melting point on top of three kilometers of ice, an anti-cyclone made months long summer holidays over the ice sheet, the albedo is down and giga tons of ice get lost every year. Next year's IPCC WG1 contribution will be an interesting reading in this context.-> continue reading
The Summit Station located at 3200m reported yesterday 0°C. As of writing all the temperatures of Wunderground's Greenland page are mostly in the two digit zone and some still close to 20°C. Kangerlussuaq had a maximum temperature of 24.2°C on Monday.
Check out this satellite view acquired yesterday by MODIS/Terra showing the great Jakobshavn glacier, the mysterious grey shaded areas and many melting ponds.
This report from last November remained a while in the local pipeline before getting blogged. It is a comprehensive and dense reading. Also it it is one of the longest - in terms of scrolling - webpage ever seen. I chose to zoomify it to get an overview and at a first glance I recognized all charts are going down. Except - still naturally - surface mass balance along the K-transect over elevation.
Everybody equipped with good pattern matching wetware will see a link to the sea ice extent graphs of the years 2007 and 2010.
Here are both highlights and a link of the report:
- Total ice sheet mass loss in 2011 was 70% larger than the 2003-09 average annual loss rate of -250 Gt y-1. According to satellite gravity data obtained since 2002, ice sheet mass loss is accelerating. -> continue reading
This is page 43 of the Cairn Energy's Oil Spill Prevention and Contingency Plan for Greenland for drilling season 2011. It is an interesting document. On page one you are referred to page 13 in the event of an oil spill. On this page you learn you have to consult the Response Decision Flowchart. And the latter tells you that given the weather is not favorable only options left are monitoring and evaluation. But how do you keep an eye on an oil spill in a long and dark Arctic night?
Looks tint spilled, doesn't it?-> continue reading
Cairn Energy formally launched its summer oil drilling program off the west coast of Greenland May 24, as the environmental group Greenpeace stepped up protests of the oil company’s Arctic activity.
Scottish-based Cairn Energy PLC claims it can safely explore for oil off Greenland's western coast. Last August the company announced that drilling in the area had detected the presence of either oil or gas beneath the seafloor.
Now Greenpeace launched a campaign and forces CEO Bill Gammell to publish their Greenland oil spill response plan. Concerned citizens are invited to send a personal email right from the ...-> continue reading
