Jøkelbugt / North East Greenland
« on: April 20, 2013, 06:08:10 PM »
Action is coming to Jøkelbugt:

A big piece of sea ice went off today/yesterday off Isle De France (Now off. Prince Henriks Ø):

Flade Is Blink / North East Greenland;

Although not exactly in the Jøkelbugt area, but a "bit" North, the action is continuing, a big piece of sea ice took off from the eastern point of Flade Isblink, the whole area will be interesting to watch over the next couple of weeks!

I noticed that too, Espen. I make it aboubt 6,000 sq km, or about 0.75 Corsicas (Neven established the Corsica a few years ago as the standard measure for large events :) ).

It looks like the stretch from there down to Shannon Island (maybe 10,000 sq km in total) is fairly thin and weak - seems likely to break up quite soon.

Big action around Jøkelbugt and Dove, the ice is getting beaten up:

http://rapidfire.sci.gsfc.nasa.gov/imagery/subsets/?subset=Arctic_r02c03.2013112.terra

I think we will see a ice free area around July, and it will be interesting to follow how Zachariea and 79 will react, and will this season be the last for Spaltegletscher?

The turquoise color often seen last year, now appears in several places on land in the Jøkelbugt / Dove area:

Spring tide comes to Greenland today & tomorrow. Watch for fast ice drifting away from shore in the next few days.

The last remaining fast ice around Nordøstrundingen / Flade Isblink is now been "peeled" of :

The break up of sea ice off Jøkelbugt is speeding up, a large piece of sea ice broke away since yesterday right outside 79 Fjords Glacier:

Update Jøkelbugt June 2013:

What can we expect in the Jøkelbugt area this season, we may get back to the situation in the early 2000s when Jøkelbugt was more or less sea ice free, the reason why I believe this could happen is due to the little sea ice we receive from the Fram Strait (export) 2013, I expect the sea temperature will be relatively higher this season and with that more (fast) sea ice melting. The last 10 years we have seen the fast ice was grounded due to the shallow water of Belgica Bank, this may not be so this season and we may see the same situation as seen below on the image from 2003.
Note the fairly big retreat of Spaltegletscher, during the past 10 years ( 6 - 8 km).
Both the Nioghalvfjerdsbræ (79) and Zachariae Isstrøm, is more or less the same, the tongue of the latter is in the process of being separated south of Lambert Land though.

The fast ice of Jøkelbugt is changing color now from white to turquoise, a clear sign of melting.

Thanks, Espen, for that information.  I almost asked a day or two ago how old the remaining fast ice is.  Shoreward of the 2003 area (now 10-year old ice), are some of the ice shelfs in this area ancient?

Tor,

Ancient? No, not along the East Coast of Greenland, but there may be a spot or 2 on the North Coast, Hunt Fjord may be one of them?

Tor;

No there is a Hunt Fjord in the very north of Greenland, Johannes V. Jensen Land, I suspect there is a Ice Shelf in there, but not 100% sure, have not been there lately ;).
Not to be mixed up with Ward Hunt in Canada (Ellesmere Island).

I am pretty sure now that we will see Jøkelbugt free of fast-ice by the end of this melting season.

From DMI:

An iceberg (island) named Topp supposedly "born" in the Jøkelbugt area, is now located south of Greenland, and passed Kap Farvel already, I will report more on this when back from my travel.

Tried to upload yesterday in Praha, but line to bad. I will try this time from Leipzig:

As you can see from the image below, the whole area of fast ice  in Jøkelbugt in now broken up into zones, this is by the way the last fast ice in North Eastern Greenland , depending on how long the melting season will last this season and refreeze begins it will be be very interesting to follow.

Espen,
I notice your name is occasionally on the images, just as a glacier or island name is occasionally included.  I imagine looking at an enlargement of the image and seeing you right there! :)

Related to what you wrote, I imagine this x-tongue now fast ice might be quite thick.  But I don't know whether to image in my mind 15 m thick or 150 m thick ice.  Do you know?

(If I'd attended my 2nd choice graduate school in the 70's, I would have done field work on Greenland, and would maybe have answers to my wunderings.  But I went south instead.)

Hi Tor,

I believe the x-tongue, now fast ice, will remain there for many years, the only difference now is it will not be supplied with new ice from Mummy (Zachariae). And will be attacked from 2 fronts.

The remaining fast ice located of Jøkelbugt is at least going to be halved there is a large crack right in the middle of "ice island", if all this fast ice will start to move, it will be the first time in about 10 years.

It seems like it is the eastern part (with a cross) that is moving, I believe the rest is either anchored to the bottom (Belgica Bank / shallow water) or to Tobias Island.
