Greenland and Arctic Circle / Kofoed-Hansen Bræ / North East Greenland
« on: August 28, 2013, 09:13:32 AM »
Kofoed-Hansen Bræ, is another glacier in the Storstrømmen Glacier complex, found in the opposite end of Storstrømmen and with a terminus facing north between Sønderland to the west and Nordmarken / Søndermarken to the east which is a part of the Jøkelbugt area.
See GEUS map below.
The width of the glacier terminus is +/- 10 km depending on when and where it is measured.
The glacier has shown some retreat between 1973 and 1990 on an average of 6 km again depending on where it is measured.
Since 1999 to 2013 the glacier only moved a little forth and back.

Arctic sea ice / Commercial interests in the Arctic
« on: August 10, 2013, 05:46:22 PM »
According to a Danish Daily China expects 15 % of Chinas export to be transferred via the Arctic sea in 2020.

Lindhard Island: This more or less unnoticed island in Dove Bugt and Borgfjorden, may become navigable for the first time in satellite history, only 800 meter of glacier ice remains between Bagfjorden and Bræfjorden, and may also be the end of story for 2 fjords?
Any suggestions what this new sound should be called?

Arctic background / How about the Inuits?
« on: July 25, 2013, 10:40:48 PM »
I believe there are many similarities when talking about Inuits and Native Americans, please watch this very interesting video:

I have done some studies with C. H. Ostenfeldt Gletscher one of the very large outlet glaciers in the North of Greenland, and I realized the not so big giant anymore retreated up to 24 km over 14 years from 1999.

Please click on the image to enlarge! It is very large

Arctic sea ice / Arctic Image of the Day
« on: July 05, 2013, 03:04:48 PM »
Just for the fun of it, if you find some funny motives along your studies in the Arctic Region you can post them here, here is the first one I picked up today, it is called Birdie Namkheng

Namkheng (น้ำแข็ง) = Hard Water = Ice (Thai)

Arctic sea ice / Bremen Sea Ice Map
« on: July 01, 2013, 09:22:30 AM »
The Bremen map has been my general favorite tool when watching the the sea ice over some years now, but the image from June 30 amazes me, it looks like the power Mc Clure Strait is reaching into Siberian territory:

Here is to be a animation showing the tongue separation / calving in August - September 2012:

Since I have problems uploading this animation (load-restrictions?) it is 2,3 mb only ::)

You can see it here hopefully! If not please report back ;)

Independence Fjord / Hagen Fjord / North Greenland.

Independence Fjord is one of the large fjords of Greenland, contain 2 glaciers Marie Sophie Gletscher and Academy Gletscher.
Not much action was seen here during the last 30 years, Academy Gletscher did some movements forth and back, though.
In the Independence branch fjord Hagen Fjord is Hagen Bræ situated, and there the situation is much different. This Glacier retreated approximately 20 km since 1978, and about 12 km alone since 2003.

To be cont. first post lost :o

As you probably know, Steensby Glacier did the first ever recorded calving on August 24 2012 and  was reporter by members of the Arctic Sea Ice Blog, a more detailed report on this event can be studied at "From a Glaciers Perspective" by Mauri Pelto: http://glacierchange.wordpress.com/2012/08/25/steensby-glacier-calving-event-and-retreat-northern-greenland/

It will be interesting to watch if the the Ice Island S1-2012, will be allowed out of the "narrow" (+/- 4 km) fjord of Sankt Georg Fjord where Kap Hunt reaches out from Warming Land.
Images from Modis and GEUS.

The black and white image is from Kap Hunt where Daniel Bruun Firn, Warming Land is seen in the background. GEUS

64
Where the 2 great glaciers L. Bistrup Bræ and Storstrømmen meet, big cracks have been seen on several Modis images over some time now. Last melt season, we saw substantial melting in this area resulting in Borgfjorden reaching further inland and even Bræ Øerne was almost free of surrounding ice at the end of the melting season 2012, it will be interesting to follow  this area over the next coming months.

Greenland and Arctic Circle / Wandel Sea / North East Greenland
« on: June 06, 2013, 12:44:03 PM »
Wandel Sea:

A big piece of sea ice is on the move north of Prinsesse Margrethe Ø / Island aprox. 5000 - 6000 km2 or similar to + / - 90 times Manhattan!

Greenland and Arctic Circle / Inland calving.
« on: May 25, 2013, 06:47:30 PM »
Unnamed Glacier North Greenland.

Just stumbled over an image from 1984, a massive calving happening ? far away from open water in N. P. Johansen Land (North Greenland). Calving width 2 - 3 km.
Probably due to emptying of a sub glacial lake. Luckily no people live in this area.

Greenland and Arctic Circle / Petermann Fjord / North Greenland
« on: April 30, 2013, 09:23:22 AM »
Southern shore:

Joe Island/ Petermann Peninsula / Kap Morton /  Kap Lucie Marie /
Constance Glacier / Kap Handy / Edith Glacier /
Faith Glacier / Cecil Glacier /
Kap Bemerton / Kap Coppinger / Kap Godthåb / Kap Schouby / Romer Søer (Lakes)/


Since it is one of the most watched places in Greenland, at least among ice enthusiasts, I think it's interesting that we get some place names from the area.

Starting from the mouth of the Petermann Fjord, to the right (southern shore) we find Joe Island *) and Kap Morton and Kap Lucie Marie, about 10 - 15 kms inside the fjord we have 2 small glaciers Constance and Edith , the survival of these 2 glaciers is questionable since the ice cap at the top of Petermann Peninsula seems to be retreating. 50 - 60 kms from Kap Morton we find Faith Glacier and Cecil Glacier the first is still flowing into the Petermann Glacier (PG) in the fjord, the latter glacier seems to be starving (retreating) and have no direct contact to PG.

*) Joe Island named after the Inuit Joe Ebierbing, Hannah Island in Bessels Fjord  the next fjord south of of Petermann Fjord is named after Joes wife Hannah. See more:
http://en.wikipedia.org/wiki/Ebierbing
http://www.nunatsiaqonline.ca/stories/article/65674taissumani_march_81/

The following places / names are measured from  Kap Morton.
Kap Bemerton 75 km
Kap Coppinger 85 km
Kap Godthåb 110 km
Romer Søer (Lakes) 115 km 2 lakes a about +/- 50 km2 , best seen in July - September.
Kap Schoubye 130 km

Greenland and Arctic Circle / Alert: Heavy Cracking over GIS?
« on: April 21, 2013, 12:03:35 PM »
What on ice is going on here? 2 or more big cracks are seen over the GIS just south west of Dronning Louse Land / North East Greenland::::::

Arctic sea ice / IJIS
« on: April 18, 2013, 11:56:37 AM »
IJIS is really heading south now April 17, 2013:

13,174,375 km2

Now at 2000s average, but with this attitude go below that within days, easily.

Arctic sea ice / The Aftermath
« on: April 16, 2013, 09:00:03 PM »
We are now on the road of no sea ice in the Arctic during the summer season, my guesstimates it will happen sometimes +/ 2016 (less than 500.000 km2), after that, I then believe this situation will continue for a short period where the sea ice free period will be extended mainly by starting earlier and earlier in the melting season.
As said I believe this is a interim situation, and I have problems to understand what will happen next, will the melting continue or will changing sea currents and/ or weather patterns level of thing?
Or will it all end in a Ecopocalypse© (Freewayblogger) , and in what form?

75
Just studying the recent Modis 250M from top of Ellesmere Island, I am surprised not to see any shades from Ice Shelf, I assume there is level difference between the Sea Ice and the Ice Shelf.
What are the latest report about the situation, is it still alive?

Dronning Louise Land

North East Greenland.


One strange place in North East Greenland is Vedel Sø (Vedel Lake). It is situated in between Pony Gletscher to the west and Ejnar Gletscher to the east, to the south is Carlsbergfondet and to the north Dronningestolen. Even though the Vedel Sø is situated at least 150 km from the open sea when that is ice free, Vedel Lake seems to have it own life, since it is ice free already in mid February, that can be watched by Modis 250m images from February 23 onwards.
The question is what is actually happening here, do we have hot springs related to some special metals / minerals or?

Advise: To find Vedel Lake use this map: http://geuskort.geus.dk/stednavnedb/#zoom=2.7731001719519117&lat=8556736.1125766&lon=538667.32015839&filter=vedel

Find: Dronning Louise Land, then Carlbergfondet, and zoom in a much as you can, after localizing Vedel Sø, swap to Modis (in another browser window)

Reposted from Arctic Sea Ice Blog;

Jakobshavn Isbræ/Sermeq Kujalleq;

The whole coast north and south of Ilulissat Icefjord, is almost without snowcover and the "ice"fjord is nearly free of ice debris from the glacier, the blue ice color up the "hills" from the coastline, indicating start of melting:

Petermann looks suspicious, will it surprise us once more this season (2013)?
