Just to let you know, within the last 24 hrs. open water was seen near the webcam, and the latest image shows a pressure ridge very close too.

On the first image you see the open water in the background.

On the second you see the new ridge.

I wonder how long these cameras will survive - the last couple of days images from Bremen seem to indicate the ice near the pole is getting very thin!

Neven · « **Reply #5 on:** May 01, 2013, 07:15:16 PM »

Always check the satellite images first, Jim. Sea ice concentration near the NP is practically 100%. The discoloration is an artifact which is seen often on Uni Bremen SIC maps. Only if it persists for several days in the exact same spot there's a possibility that SIC is going down.

Jim · « **Reply #6 on:** May 01, 2013, 07:25:31 PM »

Hi Neven,
I get what you are saying, but the Bremen chart was similar yesterday as well. I had a look at the EOSDIS Worldview image for today, and zoomed in on the pole - although there is a bit of obscuring cloud, there does seem to be a fair amount of break-up in the ice near the pole.
Is this just normal ice shifting about? (You know how I feel about jumping to conclusions too quickly

)
What do you think?

Neven · « **Reply #7 on:** May 01, 2013, 07:34:58 PM »

I think it's still too early for really extraordinary things to be visible from space. Ask me again towards the end of the month.

Jim · « **Reply #8 on:** May 01, 2013, 08:10:39 PM »

Very true Neven - I've marked the calendar

Espen · « **Reply #9 on:** May 01, 2013, 10:56:17 PM »

Still believing it is not a ridge?

I think what you call dark shadow, is open water (image # 1 above):

ice concentration (as of April 30th) isn't too great in the area:

Looking at the ice using ArcticIO's site you can see large cracks in the general area of where those webcams probably are. I don't know how to pinpoint them but take a look yourself.

how to pinpoint.

If you have coordinates it goes like this:

http://www.arctic.io/observations/65544/2013-05-02/8-N88.364511-E76.877619/Cracks

If the feature doesn't move drop the date:

http://www.arctic.io/observations/65544//8-N90-E0/NorthPole

Edit: A bit more explanation: the number 65544 tells the map to show the Arctic + a marker. Number 8 shows only the map and no marker. The text at the end of the URL will show up as marker, code whitespace as %20. No date tells the map to load images dated now minus 28 hours. The scheme is :

arctic.io/observations/[map+overlay]/[date]/[level-latitude-longitude]/[text]

"

I like the last daily average graph displaying a maxima shift linked with the effect of the sun, the thinner the ice the earlier the maxima. This matches exactly what I have observed. For 2013 at 75 North 95 W the under-ice is melting for close to 12 hours daily. Will post the first 12 hour underside net melting, it could have been yesterday, but I await several days of repetition.

I also remade my calculations about the North Pole cam horizon drop which appears to be very large. I scratched my original calculation and await more pictures. The drop appears beyond all previous observations, this requires more evidence , but may be indeed linked with the recent ridging, suggesting a lot of thin ice about."

ghoti · « **Reply #15 on:** May 04, 2013, 10:16:10 PM »

Pity that the north pole cam photos archive hasn't updated beyond May 2nd photos.

Espen · « **Reply #16 on:** May 04, 2013, 11:55:25 PM »

I dont know if it is polar bears or ridges that is problem, but no "live" streams at the moment!

Peter Ellis · « **Reply #17 on:** May 05, 2013, 12:27:39 AM »

The problem's not in the Arctic. If you go to the archive pages for the individual cameras, the photos are still being uploaded, it's just the front page that's not updating.

http://psc.apl.washington.edu/northpole/NPEO2013/WEBCAM1/ARCHIVE/
http://psc.apl.washington.edu/northpole/NPEO2013/WEBCAM2/ARCHIVE/

The most recent photos in each directory are dated 04-May-2013 12:45, i.e. less than 11 hours ago if that's GMT, and under 6 hours if (as I suspect) it's dated according to some US timezone. Photos are being uploaded regularly every 6 hours.

pikaia · « **Reply #18 on:** May 05, 2013, 12:43:15 AM »

The directories say "last modified" on May 4th, but the file name and the date within the image both indicate May 2nd. So something strange is happening.

Vergent · « **Reply #19 on:** May 05, 2013, 12:52:29 AM »

Nothing strange is happening. The images are stored in the camera until there is a good satellite link. You cant use geosynchronous on the pole. You have to wait for a polar orbiting com satellite, The images are waiting their turn. As for the horizon, the camera is settling in the snow.

Donna,

you are right, that reads very concerning. But some comfort could come from the fact, that horizon changed much only on the ridge/lead side - that may not be the typical situation around the North Pole. And the early sublimation of snow is not that astonishing, if you condsider the warm Siberian air, wich is pulled just over the Pole towards Fram. It is not lower than -10°C there for allready some days - so just the usual AGW with some artic amplification again...

Peter Ellis · « **Reply #21 on:** May 05, 2013, 12:04:22 PM »

If you want the precise conditions at the camera site, here is the atmospheric record:
http://psc.apl.washington.edu/northpole/PAWS975420_atmos_recent.html

... and here is the co-located mass balance buoy measuring the thickness.
http://imb.crrel.usace.army.mil/2013B.htm

It's hovering around -10 degrees C, the ice is ~2m thick, with a very thin snow layer. The ice is getting very slowly thicker, i.e. no melting yet, of snow or ice.

Peter Ellis · « **Reply #23 on:** May 05, 2013, 08:06:28 PM »

Sorry, I thought you were complaining about the front page, which is still stuck on April 16th/17th for some reason.
http://psc.apl.washington.edu/northpole/

As Vergent says, the reason the archive lags a couple of days behind the actual picture date is likely due to intermittent satellite uplinking. It seems to be a reasonably consistent lag, so I don't think there's been any major change recently.

ghoti · « **Reply #24 on:** May 05, 2013, 11:58:16 PM »

Except the weather data hasn't updated for a few days on two of the buoys closest to the pole as well. 2013B and 2013E at http://imb.crrel.usace.army.mil/newdata.htm are behind in updating data. I hope this isn't a serious communication failure and that the data will update soon.

Is that sun reflecting off melt ponds on the left hand side? It's minus ten degrees, so surely not! Bare ice?

Espen · « **Reply #31 on:** May 16, 2013, 03:23:22 PM »

Not melt ponds, but probably more likely surface melt ( 1 - 5 mm down), and that can happen in even very low temperatures.

Espen · « **Reply #32 on:** May 28, 2013, 11:51:53 AM »

jdallen · « **Reply #33 on:** May 28, 2013, 09:10:26 PM »

This isn't a surprise to me. I've been watching temps for several days now, they've been low single digit negative to slightly above zero, all across the pack.

ghoti · « **Reply #34 on:** May 29, 2013, 01:08:10 AM »

Except the data from the buoy near the pole accessible via http://imb.crrel.usace.army.mil/2013B.htm show the air temperatures well below zero. Looking at the photos from the north pole cams has shown mostly heavy overcast.

My guess is snow melting on the heated camera dome.

jdallen · « **Reply #35 on:** May 29, 2013, 02:53:43 AM »

That buoy showed a temp of -2.8C, which is in the range I mentioned. That is just 1 degree below the freezing point of our new ice. It is well within bounds for bottom melt to be underway in earnest, by way of increased heat flow from ocean into the ice, rather than *through* the ice.

Wind and isotherm charts suggest a fairly large, direct input of heat is underway, possibly the flip side of the arctic breakout our correspodents in Europe have experienced recently.

Nah... It looks like the shadow of a ridge in the ice - have a look at some better lit images, as below, and the ridges are clearer.

Clearly, the rain is something very powerful to melt the ice !
For the moment it is cold enough to freeze the water but not for a long time now !
Open water not far from the pole ! I guess the pole is in the left-lower corner of that modis tile.
