Once airborne, seafloor bacteria may become seeds that promote the growth of ice crystals, an important step in the formation of Arctic clouds.

 

Welcome Celt...

I do not seem to be able to link to the above..

Try and just display it as a link instead. Anyone else have the same problem?

 

First posting on this thread … I am thrilled for you. 

I hope that you continue and it gives you much interest.!

Your post I am sure is interesting, I am just a bit worried as to how these bacteria on the sea floor get into the atmosphere. For at least a third of the year (maybe more) they are cut off by the ice?

I spent some time a while ago  looking at chemistry/biochemistry research into the various forms of sea life on the ocean floor up there. It was very interesting as they claim that from the layers they found on the floor and from that the different type of biogenetics there that they could tell eg that the Arctic had suffered periods of clockwise and also anticlockwise ocean movements lasting about 10,000 years.

This was from the fact that sediment was different depending upon whether the ice layers were thick or thin.

It gave a pretty good 'proxy' for the past climate of the Arctic.

I am sure that this sort of research will help our understanding of the Arctic climate.

US nic out early today....

Snow cover made more smallish gains, with Switzerland now covered as well as the aforementioned snowfalls around Tehran.

Ice situation...

Kara increased today after the large drop  of yesterday. General moderate increases in most sea areas apart from Barents and Greenland which are still seeing the effect of the southerly winds.

Even though we are lacking a lot of ice, we still have much more old ice than in 2012

Todays Masie info..

A larger than expected century gain of (+115K). 40Kmore than average.

With the exception of Barents(-9K) and Greenland(-6K) all areas recorded increases.

Kara (+24K) started to recover, and Beaufort (+1K,and now nearly full), and Chukchi(+31K) continued their more rapid late refreeze. Also of note today is that Bering started to ice more rapidly with a (+22K) increase. Could we be on the point of a new  rapid refreeze in this area.?

Elsewhere Baffin (+18K) and Hudson (+26K)  continued with a steady increase.

On  other Masie charts (on thickness) -  which has been way lower this year there are signs that the thickness is now also gaining, and encouragingly it is on the Russian side for the first time for a while -

 

Notice the thicker ice showing in the gap between the ESS and Laptev and above Kara, and the pole -

compared to this from a month ago -

The ice in this area, if becoming thick enough, will go on to  produce more multi-year ice.  The lack of a decent freeze on the Russian side in this area is what has resulted in less of this multi year each year for the last 5 - 10 years.

This is the ice that needs to be watched (and nurtured!!) if you are interested in the long term future of the Arctic.

Turning cooler (lol) in Barrow, Alaska, now down to -13 with snow, and forecast to get colder,  down to -25 soon with more snow.

So my forecast (prediction actually) that the end of this week will see it 'iced up' is still possible?

It will be frozen solid soon enough with a run of those sort of temps?

Looks likely the second half of November will make up for the less cold first, perhaps ending below average?

Pretty much guarantee if it is cold in Alaska it will be warm here as it is and vice versa..they had a very warm year thus far...here it has been the coldest year since 1996.

Interesting now to see record breaking cold in Asia, Europe and N America..

Onto to todays Masie run - 

An increase of 112k Km2.  70K Km2 above the long term average for the date.

Normal rules apply with decreases in Beaufort(-2K, now, also full),Central (-4K also full) and more surprisingly Hudson(-2K).

Elsewhere gains in Kara(+35K), now almost back to 3 days ago when the small cyclone struck), ESS(+14K), and impressively(+40K) in Chukchi.

The ice is being pushed towards Bering(+15K) and I expect that Barrow can see the first ice formations out to sea, as the coastal ice advances around the peninsula. (webcam down at the moment)

Greenland (+8K) and Baffin(+7K) continued their steady refreeze.

The CAA is now full. Barents had no change.

For anyone interested in the Mosaic project, an update came in this morning.

It is not so easy 'negotiating'  the arctic ice any longer......

They are suggesting that their Russian supply ship (the AF) could be starting to have problems after a few days at -25C,

The captain seems to be continually  concerned about his ship (the second of the expedition), also becoming ice bound now that he has unloaded large amounts of diesel and equipment. It seems she is riding high in the ice now and the specially strengthened bows are above the ice line. It also seems as though the recent storm has caused much ice movement including ridges and compressions, causing some loss of equipment, and although the temperature rose above -10C for a short time, it is dropping again.

Talk of surprisingly thin sea ice being discussed 3 weeks ago is now being superseded/suppressed. 

The AF is due to return to Murmansk shortly to bring on more scientists and equipment and fuel to the Polarstern, for her voyage across the pole.

Let us hope that do not have to call in an icebreaker.!!

A Russian ship is playing a difficult game in the high Arctic: trying to stay in the thickening winter sea ice without getting stuck.

Still watching the NH ozone situation.

It is established that Ozone in the troposphere is a greenhouse gas 'warming' agent.

It is established that Ozone in the Upper Stratosphere is a 'cooling' agent.

Most Ozone resides  in the stratosphere - 80% plus of all the earth's Ozone.. 

It is accepted that this winter there is more Ozone in the earth's upper atmosphere and stratosphere. (the Ozone hole healed in the Southern Hemisphere at its earliest point ever since it was measured and  formed), and it was totally removed in the first week of November.

In the last 3 decades, Ozone has been  removed by 'high' aerosols (Fluoride and Bromides mainly) at very high levels in the stratosphere under very low temperatures (below -80C), This has not happened to the same extent this year.

I will present graphs of this when they become available at the end of the year.j   

This means that the earth's Ozone concentration is heading back up to the levels achieved when Ozone was first measured. (same year as the Arctic ice was first measured by satellite- strangely enough 1979). When it just so happens that sea ice was at very high levels.

Ozone in the stratosphere warms under the background bombardment from both solar and background.

The natural effect of a warmer stratosphere is a cooler troposphere.

So where are we now???

The recent cold out break in the Arctic was accompanied by a large increase of Ozone over Baring and Chukchi. (see my previous forum daily reports)

Since then Ozone has migrated to the North of America (is it coincidence that it too has turned very cold there?), but is now reforming in the East of Asia and is steadily moving back towards Baring in the next few days.

image.thumb.png.acbf54ec4872c76b52d27d57d5d09e28.png  earlier  this week  11th, 

and now 17th    image.thumb.png.dfbc6fac7259fcf2c458e460d348389c.png 

Ozone can be seen reforming in Siberia and extending into Baring and Alaska  once again on the next wave..

So let us see what happens this time. 

Temperatures (according to DMI) have rocketed up by more than 10C over the Arctic in the last week, all this while ice growth in this area has grown aggressively, (and yet it has slowed in the west). 

image.thumb.png.245904627ffb64134aeb9fd074fd1ab5.png

I do not know if there is a connection, but it is all very interesting, and I will continue monitoring Ozone in conjunction with sea ice levels.

Morning all.... US NIC this am...

snow little changed in Europe but increases both west and south in Asia looks impressive.

 

Ice.... is almost identical to yesterdays report with small losses in Barents and Greenland, due to the southerly Atlantic, but big increases in the south of Kara and once again ESS and Chukchi (where  the byte has almost gone).Bering (US side) continues to increase rapidly.

As a follow on from the above report on the Mosaic project (more minor problems I am afraid)...

Scientists are  finding difficulties in carrying out their experiments due to contamination caused by the icebreaker Polarstern having to maintain one of their  diesel engines fulltime in order not just to carry out the experiments, but also to keep the ship warm!.

Experiments in the immediate vicinity are a no/no due to heat and soot diesel pollution (UHI??), and they have 'lost' their large staircase which enabled them to get onto the ice easily. They are using 17 tons of diesel a day, -  not a problem - but it means that they will need fairly frequent re-fuelling and where is the ship heading?.. 

Apparently the noise and also the soot output are affecting many of the experiments, and also Polar Bears are chewing up some of the power cables to the outlaying experiments. I must say that I am surprised that the mums take their cubs so far out on to the ice.

Life is not easy for these students, and some are coming off (2 weeks stay) reporting that they have doubts that their planned experiments can be achieved.

And to add to their problems - they are still drifting North eastwards towards the pole and not to Svalbard and out into the Fram,   as they expected. 

All very interesting …..

Thanks for the continued updates MIA.

Great to see the Kara nearly full...hopefully the natural shield of NZ will protect the ice from any warm Atlantic incursions! A relief to see the Chucki making sustained big gains at last, too.

Re MOSAIC - were they not expecting to have to heat the ship with their diesel engines? Slightly distressing to think they're burning so many tonnes of fossil fuels each day in the High Arctic, and contaminating the ice with soot, etc.

I'm also amazed they didn't think the engine's outputs would contaminate their experiments...that seems a massive oversight. Or am I missing something?

Very interesting to monitor their drifting in any case and see where they end up!

Hi Strav..

I think that the more experienced on board were anticipating these sorts of problems, and the captain of the AF is obviously aware of the dangers ,  but most of the researchers on board are probably  on their first winter expedition. 

The problem with the fuel  is that they are going into thicker ice around  the pole than they were anticipating, hence the difficulties of getting to them with their 'refuelling' and stores provisions.

It is the current track that is causing the worries... they were expecting to drift along the 'relative edge' of the ice towards Svalbard. Instead at the moment they are headed straight at the pole.

Todays Masie on the sea ice...

More of the same ….    with a gain of 75K KM2 - down on recent days,  but still 30K above average..

Barents(-9K),Greenland(-6K) and Central(-9K) all down on the Atlantic forcing.

Bigger gains in the Eastern arctic with Beaufort(0), Chukchi(+25K) and ESS(+16K) starting to move towards Bering(+12K) which is reaching out now to greet the main pack.

With cold forecast to move further south into Bering, it should soon enter the straits area. 

Baffin(+2K) and Hudson(+19K, making up for yesterday's blip), continue with re-freeze,

Oh yes Kara... added (+20K), with big gains connecting up over the NZ bite, which more than compensated for the main pack being  put under pressure from the Atlantic revival.

The SOO and Baltic remained relatively unchanged.

Todays recent weather forecasts  look to be unusual for about a weeks time with the  vortex moving to the NE Arctic.

It will certainly be interesting to watch the impact on the ice.  if it happens!!

USNIC this morning...

Similar to yesterday for snow with another push south and east in Asia.

Sea ice shows average size gains again in similar areas with the exception of Kara - where it is up and down like the proverbial.

Also the 'Atlantic' front pushed southwards today in both Barents and Greenland, apparently reversing the last few days of losses.
