For the first time I have watched the Arctic, Foxe Basin is sea ice before Hudson Bay according to Bremen:

Clue? - temperatures have been somewhat like this for some time.

There could be 100s more threads but my interest is mainly northern glaciers.

An irrelevant calving happened at Spaltgletscher AKA Big Foot between Aug 1 and Aug 2 2019:

On the same day Gammel Hellerup (I think), just to the south, moved fairly significantly:

Nope! Gammel Hellerup is a land based glacier. The one you are showing in the animation is actually Zachariae Isstrøm.

Hello Oren,

The glacier Gammel Hellerup was named by Svend Sølver during the  Mørkefjord expedition in 1938-39, Gammel Hellerup was the high school he went to, I actually told the story to the rector of the school today, a few years ago, and he was not aware of a glacier named Gammel Hellerup?

Almost the same story I could tell about Zachariae Istrøm, I met Bobby Zachariae (a well known researcher here in Denmark) once and told him about a very impressive glacier that was named with his family name and not only that but after his grand grand something Georg Hugh Robert Zachariae, he thought I was joking, but luckily he had a smartphone and googled it instantly and thanked me a lot for the information.

Another example of a Fjord being prepared for sea ice removal is the large Independence Fjord about 230 km in length including Hagen Fjord, Danmark Fjord, Jørgen Brønlund Fjord, Astrup Fjord, Sjælland Fjord, Holbæk Bugt and a few more. The images in the animation are from yesterday and today:

Arctic sea ice / All Greenland Fjords could be Sea Ice Free in 2019.

The real big difference, in my opinion, to the Sea Ice situation in 2019 compared to especially 2012 and 2016, is the  sea ice around Greenland and particularly in the extreme north of Greenland including Wulff Land, Nares Land, Freuchen Land, Nansen Land, Johannes V. Jensen Land and Peary Land where at least 30 fjords, sounds and bays alone are located.
I expect all of these fjords sounds and bays to be sea ice free by mid-September 2019 and this never happened before in the history of satellite surveillance, and both 2012 and 2016 looks pretty cold compared to 2019 if you ask me, take a look at the animation you may need to click on it to enlarge and play!

Breaking Old NewsAnother calving at Petermann Gletscher, this time probably the oldest satelite documented calving at Petermann, the calving happened sometimes in the 1976 melting season, notice the front of Petermann at that time reached all the way to the mouth of Petermann Fjord.

Why is this top moving??

Simple, 1928 picture taken from a position to the right of where 2017 picture is taken from. The middle peak is clearer nearer than the two distant peaks.

or put another way, "I note the perspective is off a little"

I understand what you are saying, but I find it strange?

I don't know the name of this glacier. These blocks that calved on the 26th are around 1 km across. It's at 75.572625,-58.237839

Many of these glaciers along the west coast of Greenland are calving.

It is Sverdrup Gletscher:

« on: July 24, 2019, 06:05:14 PM »
For those of you who are so interested in congestion issues in Nares Strait, you should be looking up for loads of debris from several glaciers in the north, provided the ongoing melt situation:

Sankt Georg Fjord - Steensby Gletscher got a pretty big stock.

Sherard Osborne Fjord - Ryder Gletscher got some nice big ice cubes.

Victoria Fjord - C. H. Ostenfeldt Gletscher got some of those samples too.

J. P. Koch Fjord - Henson Gletscher got what is left.

« on: July 21, 2019, 06:56:16 PM »
I am not the big sea ice interpreter, but I find it interesting that Foxe Basin is ahead of Hudson Bay when it comes to melting of sea ice? That it very unusual I think?

124
Breaking NewsAfter years of studying images and datas as you can read above, I can now with full documentation from Landsat 1-5-8 and Sentinel 2 declare a new free island of the coast of North East Greenland, this time we have Lindhard Ø a pretty large island in the release "competition" with aprox. 260 km2 and big enough to become the 10th largest island in Denmark (Greenland and Faroe Islands not included).
It is not every year we see island releases, we had a small one this spring in Giesecke Isfjord https://forum.arctic-sea-ice.net/index.php/topic,1371.msg194164.html#msg194164 and a very spectacular release in front of Kjer Gletscher in 2017 https://forum.arctic-sea-ice.net/index.php/topic,1209.msg109997.html#msg109997

https://twitter.com/Ecoverycom

I have 2 sets of documentation one from Landsat using data all the way from Landsat 1 (1973 - 2019) and the more recent data from Sentinel 2 (2016-2019).
As you can see from the animations below big differences have taken place during this period.

125
While we are waiting for Petermann to calve, just a reminder we are also loosing a lot of ice next door to Petermann Fjord,and that is on top of Washington Land, the ice caps here will soon be history:

126
I got some maps from the region but none got a name for this particular lake (but I am sure there is a name), I found names of neighboring lakes see attached:

127
Espen,
It is especially dramatic as September image is from near (at) the end of the melting season (2016 has a higher snow/ice elevation) while the June image (2019) is from near the beginning of the melting season.

And note the ice that is left is becoming very thin you can allready see the contours of the rock underneath, so in a few years it will (forever) be different again!

128
Confirmed, Mag!

She cracked quite a lot today.

I'm afraid this is the end of this poll already. :(

You will need one of the calved icebergs from the north of Greenland, to block Nares Strait, but they are rare nowadays, there are few minors left from Steensby, Ryder and Ostenfeldt glaciers in their respective fjords, but all of them do not have the size to block Nares. So  time is better spend watching something else?
Remember The Petermann Calves went down Nares without problems?

129
I was looking for a map with place names for the north-northwest corner of Greenland and came upon this detailed Wikipedia map.  It appears to not include places like Oodaaq/Oodaap Qeqertaa (which may not exist any more) but looks very useful.  I also found a Mapcarta map, but place names don't exactly match locations!

Does Espen have an opinion?

That Wikipedia map you are pointing to is actually a US Navy map, they are usefull to some degree but not complete.

130
An unmasked view would also be nice to compare three years of the evolution of the calving front...

Not realy since the the retreat of the glacier at both the northern and southern branch were further back in 2016.

131
Espen,
It is especially dramatic as September image is from near (at) the end of the melting season (2016 has a higher snow/ice elevation) while the June image (2019) is from near the beginning of the melting season.

Yes you right, thats why I picked the September image.

132
Surrounding Ice Retreat at Jakobshavn, since this is only a study about how much the ice on the rocks surrounding Jakobshavn Isbræ is affected by the climate changes, the glacier itself is masked, but watch the rocks marked with X, the timespan is only about 2½ year (September 2016 - June 2019), quite dramatic if you ask me?

133
Expect a very heavy calving next!!!!!
As promissed:
Just don't promise us an ice-free Arctic Ocean! :o

Not this or next year, but you will be very surprised when it happens, it will be be within days!

134
@Stephan
I think it may have something to do with periodicity of calving or the changing speed of the glacier or a known period after some artifact? What suspence!
I doubt you are doing anything dirty Espen.

You are right, I am not doing doing anything real dirty, but only using the resourses that are available!??? And that is info, the "new" world power!

135

As promissed:

How did you know? What were the signs to successfully predict it?

Like in any other business, even in glacier observation field, dirty tricks are being used. ;)

You are welcome SH. :)

I think tidal waves have some say in gnawing on the fast ice, only not that rapidly.

And if it's only for this effect: This GIF is showing a bit of fast ice in Hall Kane Basin chipping off. For how i see it, it's because a tidal wave bumping that bigger floe (which was fast ice itself) against it.

Edit!

There is  no fast ice in Kane Basin or Nares Strait, there is 1 year ice max!

All hell breaks loose above Greenland, and you guys are only interested in bits and pieces in Nares Strait?

143
No an Undentified Ice Object.

144
I've been 'seeing things' for a long time (and sometimes conflicting with 'each other'), but maybe today you'll see 'it' in this GIF made from yesterday's PolarView.  I see a trace of something (a crack?) the yellow line approximately follows .  [Click to play]   (Edit: approx. location of GIF in outline.  Petermann Fjord is 15 km wide.)

(I sure appreciate Thomas's GIFs too.)

At this point I belive it is only a UIO?

Hello Tor the 2 islands you are asking for are found in some few maps like this one from GEUS the northernmost of the "islands" (sand gravel) is located at 83.40 where as Kap Morris Jesup is at 83.39 see attachment

147
Here we got 1 more example of data received for 2 different sources (Nasa and Sentinel 2) thanks to Jim and his crew on the Ice Bridge Mission 2019. The images from Nasa is showing half of the calving front and the Port Side og the glacier.

148
thanks for sharing this Espen, but could you let us know where (which website) the Nasa image comes from, I was unable to find it?

It is from the Ice Bridge Project Newsletter

A new island was released recently from the Ice Sheet, inside Giesecke Isfjord in front of the large glacier that is part of the Giesecke Bræer: Click on image to animate

Just received, here is what you can get within hours, images of 2 Ice Bergs at Zachariae Isstrøm from 2 different sources Nasa (from a plane) and Sentinel 2 (from a satelite).
