Arctic sea ice, Greenland and Europe’s weird weather
As I write this, I am sitting in a short-sleeved shirt with the window open, enjoying an unusually warm start to the month of May. It’s around 27 degrees Celsius in this part of Germany, pleasant, but somewhat unusual at this time. The first four months of this year have been the hottest of any year on record, according to satellite data.
The Arctic is not the first place people tend to think of when it comes to explaining weather that is warmer – as opposed to colder – than usual in other parts of the globe. But several recent studies have increased the evidence that what is happening in the far North is playing a key role in creating unusual weather patterns further south – and that includes heat, at times.
Why sea ice matters
The Arctic has been known for a long time to be warming at least twice as fast as the earth as a whole. As discussed here on the Ice Blog, the past winter was a record one for the Arctic, including its sea ice. The winter sea ice cover reached a record low. Some scientists say the prerequisites are in place for 2016 to see the lowest sea ice extent ever.
Several recent studies have increased the evidence that these variations in the Arctic sea ice cover are strongly linked to the accelerating loss of Greenland’s land ice, and to extreme weather in North America an Europe.
“Has Arctic Sea Ice Loss Contributed to Increased Surface Melting of the Greenland Ice Sheet”, by Liu, Francis et.al, published in the journal of the American Meteorological Society, comes to the conclusion: “Reduced summer sea ice favors stronger and more frequent occurrences of blocking-high pressure events over Greenland.” The thesis is that the lack of summer sea ice (and resulting warming of the ocean, as the white cover which insulates it and reflects heat back into space disappears and is replaced by a darker surface that absorbs more heat) increases occurrences of high pressure systems which get “ stuck and act like a brick wall, “blocking” the weather from changing”, as Joe Romm puts it in an article on “Climate Progress”.
Everything is connected
The study abstract says the researchers found “a positive feedback between the variability in the extent of summer Arctic sea ice and melt area of the summer Greenland ice sheet, which affects the Greenland ice sheet mass balance”. As Romm sums it up:“that’s why we have been seeing both more blocking events over Greenland and faster ice melt.”
He quotes co-author Jennifer Francis of Rutgers University, New Jersey, explaining how these “blocks” can lead to additional surface melt on the Greenland ice sheet, as well as “persistent weather patterns both upstream (North America) and downstream (Europe) of the block.
“Persistent weather can result in extreme events, such as prolonged heat waves, flooding, and droughts, all of which have repeatedly reared their heads more frequently in recent years”, Romm concludes.
“Greenland melt linked to weird weather in Europe and USA” is the headline of an article by Catherine Jex in Science Nordic. People are usually interested in changes in the Greenland ice sheet because of its importance for global sea level, which could rise by around seven metres if it were to melt completely. But Jex also draws attention to the significance of changes to the Greenland ice for the Earth’s climate system as a whole.
The jet stream
“Some scientists think that we are already witnessing the effects of a warmer Arctic by way of changes to the polar jet stream. While an ice-free Arctic Ocean could have big impacts to weather throughout the US and Europe by the end of this century”.
She also notes some scientists warning of “superstorms”, if melt water from Greenland were eventually to shut down ocean circulation in the North Atlantic.
The site contains an interactive map to indicate how changes in Greenland and the Arctic could be driving changes in global climate and environment.
The jet streams drive weather systems in a west-east direction in the northern hemisphere. They are influenced by the difference in temperature between cold Arctic air and warmer mid-latitudes. With the Arctic warming faster than the rest of the planet, this temperature contrast is shrinking, and scientists say the jet streams are weakening.
Jex quotes meteorologist Michael Tjernström, from Stockholm University, Sweden: “Climatology of the last five years shows that the jet has weakened,” says. Its effect on weather around the world is a hot topic.
“We’ve had strange weather for a couple of years. But it’s difficult to say exactly why.”
One explanation, Jex writes, is that a weak jet stream meanders in great loops, which can bring extremes in either cold dry polar air or warmer wetter air from the south, depending on which side of the loop you find yourself. If the jet stream gets “stuck” in this kind of configuration, these extreme conditions can persist for days or even weeks.
Experts have attributed extreme events like the record cold on the east coast of the USA in early 2015, a record warm winter later the same year, and the summer heat waves and mild wet winters with exceptional flooding in the UK to these kind of “kinks” in the jet stream.
Greenland and the ocean
The changes to Greenland’s vast land ice sheet also have consequences for ocean circulation, because they mean an influx of the cold fresh water flowing into the salty sea. And the sea off the east coast of Greenland plays a key role in the movement of water, transporting heat to different parts of the world’s oceans and influencing atmospheric circulation and weather systems.
There have often been “catastrophe scenarios” suggesting the Gulf Steam, which brings warm water and weather from the tropics to the USA and Europe could ultimately be halted, leading to a new ice age. (Remember the “Day after Tomorrow?)
Although this extreme scenario is currently considered unlikely, research does suggest that the major influx of fresh water from melting ice in Greenland and other parts of the Arctic could slow the circulation and result in cooler temperatures in north western Europe.
Jex goes into the theory of a “cold blob” of ocean just south of Greenland, where melt water from the ice sheet accumulates. Some scientists say this indicates that ocean circulation is already slowing down. The “blob” appeared in global temperature maps in 2014. While the rest of the world saw record breaking warm temperatures, this patch of ocean remained unusually cold.
According to a recent study led by James Hansen, from Columbia University, USA, the ‘cold blob’ could become a permanent feature of the North Atlantic by the middle of this century. Hansen and his colleagues claim that a persistent ‘cold blob’ and a full shut down of North Atlantic Ocean circulation could lead to so-called ‘superstorms’ throughout the Atlantic. And there is geological evidence that this has happened before, they say. But the paper was controversial and many climate scientists questioned the strength of the evidence.
However, some scientists already attribute western Europe’s warm and wet winter of 2015 to the “cold blob”, Jex notes, which may have altered the strength and direction of storms via the jet stream.
The good old British weather
The UK’s Independent goes into a new study by researchers at Sheffield University, which indicates soaring temperatures in Greenland are causing storms and floods in Britain. The Independent’s author Ian Johnston says the study “provides further evidence climate change is already happening”.
It never ceases to amaze me that evidence is still being sought for that, but, clearly, there are still those who are yet to be convinced our human behavior is changing the world’s climate. So every bit of scientific evidence helps – especially if it relates to that all-time favourite topic of the weather.
The study also looks at the static areas of high pressure blocking the jet stream. With amazing temperature rises of up to ten degrees Celsius during winter on the west coast of Greenland in just two decades, it is not hard to imagine how this can effect the jet stream, and so our weather in the northern hemisphere.” If forced to go south, the jet stream picks up warm and wet air – and Britain can expect heavy rain and flooding. If forced north, the UK is likely to be hit by cold air from the Arctic”, Johnston writes.
The article quotes Professor Edward Hanna from the University of Sheffield, lead author of a paper about the research published in the International Journal of Climatology, and says seven of the strongest 11 blocking effects in the last 165 years had taken place since 2007, resulting in unusually wet weather in the UK in the summers of 2007 and 2012.
Hanna told the Independent computer models used 10 to 15 years ago to predict the extent of sea ice in the Arctic had significantly underestimated how quickly the region would warm.
“It’s very interesting to look at the observed changes in the Arctic … the actual observations are showing far more dramatic changes than the computer models,” Professor Hanna said.
“You do get sudden starts and jumps. It’s the sudden changes that can take us by surprise and there certainly does seem to have been an increase in extreme weather in certain places.”
Drawing conclusions (or not?)
In the Washington Post, (reprinted on Alaska Dispatch News) Chelsea Harvey sums up the conclusions of the latest research in an article entitled “Dominoes fall: Vanishing Arctic ice shifts jet stream, which melts Greenland glaciers”:
“There are a more complex set of variables affecting the ice sheet than experts had imagined. A recent set of scientific papers have proposed a critical connection between sharp declines in Arctic sea ice and changes in the atmosphere, which they say are not only affecting ice melt in Greenland, but also weather patterns all over the North Atlantic”.
So what do we learn from all of this? Sometimes I ask myself how many times we have to hear a message before we really take it in and decide to do something about it.
Here in Bonn, not far from the office where I am sitting now, the first round of UN climate talks since the Paris Agreement at the end of last year will be kicking off this coming weekend. The aim is to stop the rise in global temperature from going about two, preferably 1.5 degrees C. We have already passed the one degree mark. In an interview with the Guardian this week, the head of the IPCC Hoesung Lee says it is still possible to keep below two degrees, although the costs could be “phenomenal”. But many scientists and other experts are increasingly dubious about whether emissions can really peak in time to achieve the goal. Current commitments by countries to emissions reductions still leave us on the track for three degrees at least.
The concentration of greenhouse gases in the atmosphere is, as the Guardian puts it, “teetering on the brink of no return”, which the landmark 400 ppm measured for the first time at the Australian station at Cape Grim and unlikely to go below the mark again at the Mauna Loa station in Hawaii.
On my desk, I have a book entitled “Arctic Tipping Points”, by Carlos M. Duarte and Paul Wassmann. It was published in 2011. Before that, Professor Duarte had explained the global significance of what is happening in the Arctic to me
at an Arctic Frontiers conference in Tromso, Norway. How much more evidence do we need? Science takes a long time to research, evaluate and publish solid evidence of change and its consequences, with complex review processes. If politicians delay much longer, the pace of climate change will be so fast that action to avert the worst cannot keep up. Meanwhile, that Arctic ice keeps dwindling – and I sense another major storm on the approach.

Earth Day, Climate pact signing – and the Arctic?
How are you feeling this Earth Day? In some ways it could mark a turning point for the planet, with some 165 countries signing the Paris climate treaty at UN headquarters in New York. But, as, always, the proof of the pudding will be in the eating. And so far, I’m not sure it is quite tasty enough.
The trouble is, signing agreements alone is not enough. They have to be turned into action. The world is heating up way too fast, and the transition to an emissions-free world is far too slow. Yes, we can do it, I am convinced. But as well as the political will to sign an agreement, we need the political will to implement measures which will be unpopular with businesses and consumers because they mean major changes to how we work, trade and live.
In the meantime, the Arctic is facing a decline in sea ice that could equal or even beat the negative record of 2012.
Sea ice physicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have evaluated current satellite data on the thickness of the ice cover. The data show that the Arctic sea ice was already extraordinarily thin in the summer of 2015 and comparably little new ice formed during the past winter. Speaking at the annual General Assembly of the European Geosciences Union in Vienna, AWI sea ice physicist Marcel Nicolaus said data collected by the CryoSat-2 satellite revealed large amounts of thin ice that are unlikely to survive the summer.
Hard to forecast
Predicting the summer extent of the Arctic sea ice several months in advance still poses a major challenge to scientists and meteorologists. Between now and the end of the melting season, the fate of the ice will ultimately be determined by the wind conditions and air and water temperatures during the summer months. However, conditions during the preceding winter lay the foundations.The AWI scientists say this spring, conditions are as “disheartening as they were in 2012”, when the sea ice surface of the Arctic went on to reach a record low of 3.4 million square kilometres.
At the end of March, the Arctic sea ice was at a record low winter maximum extent for the second straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) and NASA. Air temperatures over the Arctic Ocean for the months of December, January and February were 2 to 6 degrees Celsius (4 to 11 degrees Fahrenheit) above average in nearly every region.
This year’s maximum winter extent was 1.12 million square kilometers (431,000 square miles) below the 1981 to 2010 average of 15.64 million square kilometers (6.04 million square miles) and 13,000 square kilometers (5,000 square miles) below the previous lowest maximum that occurred last year.
The September Arctic minimum began drawing attention in 2005 when it first shrank to a record low extent over the period of satellite observations. It broke the record again in 2007, and then again in 2012. The March Arctic maximum tended to attract less attention until last year, when it was the lowest ever recorded by satellite.
Ice conditions “catastrophic”
Recently, here on the Ice Blog, I published an account by Larissa Beumer, one of a team of Arctic experts on board the Greenpeace ship the Arctic Sunrise, which has been checking the ice conditions the Arctic archipelago of Spitsbergen. From the ship, she told me the ice conditions were “catastrophic and way outside of normal variations”. She reported transport problems, with many of the usual routes inaccessible by dog sled or snow mobile. She talked of a lack of ice in places where navigation is usually impossibly up to June or July.
On thin ice
AWI scientist Marcel Nicolaus says new ice only formed very slowly in many regions of the Arctic, on account of the particularly warm winter.
“If we compare the ice thickness map of the previous winter with that of 2012, we can see that the current ice conditions are similar to those of the spring of 2012 – in some places, the ice is even thinner,” he told journalists at the Vienna Geosciences meeting.
Nicolaus and his colleague Stefan Hendricks evaluated the sea ice thickness measurements taken over the past five winters by the CryoSat-2 satellite for their sea ice projection. They also used data from seven autonomous snow buoys, which they placed on ice floes last autumn. These measure the thickness of the snow cover on top of the sea ice, the air temperature and air pressure. A comparison of their temperature data with AWI long-term measurements taken on Spitsbergen has shown that the temperature in the central Arctic in February 2016 exceeded average temperatures by up to 8 °Celsius.
Breaking ice record
In previously ice-rich areas like the Beaufort Gyre off the Alaskan coast or the region south of Spitsbergen, the sea ice is considerably thinner now than it normally is during the spring. “While the landfast ice north of Alaska usually has a thickness of 1.5 metres, our US colleagues are currently reporting measurements of less than one metre. Such thin ice will not survive the summer sun for long,” Stefan Hendricks said.
The scientists say all the available evidence suggests that the overall volume of the Arctic sea ice will be decreasing considerably over the course of the coming summer. They suspect the extent of the ice loss could be great enough to undo all growth recorded over the relatively cold winters of 2013 and 2014. “If the weather conditions turn out to be unfavourable, we might even be facing a new record low,” Stefan Hendricks said.
So the AWI researchers fear we are going to see a continuation of the dramatic decline of the Arctic sea ice throughout 2016. From that point of view, the signing of Paris climate pact comes way too late. UN Secretary-General Ban ki-Moon is stressing that this can only be the beginning, and that the mammoth task of decarbonising the economy still lies ahead. Here’s hoping the Paris Agreement will not just be a piece of paper which governments use to salve their consciences. Here in Germany, people are concerned that the government will not reach its ambitious climate targets at the present pace. Given that this country has already made remarkable progress in the transition to renewable energy for its electricity production, that is a worrying trend. And other major emitters still have even more to do if that two degree, let alone the 1.5 degrees Celsius limit to global warming is to be more than a very hot piece of pie in the steadily warming sky.

Arctic off limits for giant trawlers?
This past winter, one of the favourite fish dishes being served up here in Germany was skrei, or Arctic cod. I had the feeling this was a new trend in this part of the world, and found myself wondering why there seemed to be more about and whether this could have anything to do with climate change and easier access to fish stocks which were further north before.
My research brought me very quickly to a campaign by Greenpeace, which is tackling this very issue. The website describes the increase in large-scale fishing as a “new threat” to the Arctic:
“Investigations by Greenpeace have shown industrial fishing fleets using destructive bottom trawling are invading previously pristine areas of the Barents Sea in the Norwegian Arctic.”
Greenpeace carried out an investigation focused on part of the Norwegian Barents Sea, including an analysis of vessel movements over three years to September 2015. I called up Frida Bengtsson in Norway, a Greenpeace campaigner and author of the report on the investigation, just published in March, entitled “This Far, no Further. Fishing in the Arctic.”
She told me what she and her fellow conservationists had found out and why they are worried:
“What we’ve seen over the years is that the cod fishery that comes from Norway and provides markets in Europe and also travels to China, North and Latin America, has been expanding further north. So our research shows we are moving further and further north and into the Arctic. These areas have previously been covered by sea ice. Up to half the sea ice cover in the Barents Sea has disappeared since the 1980s”.
Given that the sea ice is disappearing anyway, I wondered whether it wasn’t a natural thing to catch some of the fish in the region:
“Research has just started to look at what’s below the sea ice on the seabed, and we’ve found things they haven’t found in other parts of the Barents Sea where extensive fishing has taken place for longer periods of time. For example, they have found sea pens, up to fifty years of age and up to two metres in height, which is very unique. So we’re calling for a precautionary approach, to not expand into these vulnerable areas but leave them alone and replace the protection the ice once offered with regulation.”
So in fact the problem is not the catching of a limited number of fish, but the effect of the large-scale industry on other species:
“We look at the size of the Barents Sea fishery. It’s very big. There are over 200 factory trawlers licensed to fish in the Barents Sea, and the footprint on the ocean environment is very large. We’re concerned that if this fishery is allowed to move into areas that haven’t been fished before, it will have a very negative impact. We’re mostly concerned about bottom trawling, where you use heavy trawl doors that can weigh several hundred kilos to put the net out and then drag it along the seabed with chains. The creatures on the seabed are very vulnerable and soft, and when they’re hit by these massive trawls they are destroyed.”
I asked what kind of preventive measures Bengtsson and her colleages would like to see?
“We think industry should move out of this area now, and we want to see Norway step up and protect these areas. We think that’s in line with what people generally want when it comes to Arctic protection. It would also mean Norway would meet their commitment towards the 2020 goals the world has set on protecting the world’s oceans.”
Alongside Norway, another major player in the region is Russia. I wondered if Greenpeace was also targeting Russian fishing?
“The Barents Sea fishery is shared between Norway and Russia. But most of the fishing activity actually takes place inside Norway. So we believe that working with the Russian fisheries, the markets that they sell to and the Norwegian government, we will find the right balance. But of course it’s also going to be important to see protection happening all over these vulnerable areas. And the Russians have already acknowledged the vulnerability for their part and have noted these as sensitive areas.
So far, the organization says it has had some interesting reactions both from consumers and the fishing industry to its report:
“It is very clear that people don’t consider that trawling for cod in the Arctic is something that is sustainable. And I think for the industry, it’s important to be at the forefront of sustainability. The indications we have from industry suggest they think it’s important and they want to take preventive measures. That is very encouraging, because I think it’s always good when we can work together. At the moment we’re seeing industry taking initiatives to find some solutions. That is interesting because it’s in line with the same pattern we’ve seen in other places, for example around the soya moratorium in Brazil. There, industry agreed to take preventive measures, to not expand soya production into the Amazon.”
Of course all this relies on pressure from consumers, using their purchasing power to make fishing companies do certain things, like stay out of certain areas. But can ordinary people find out fish is coming from an area of the Arctic it should not be coming from? Not so easy, it seems:
“Unfortunately, today that is very difficult for a consumer. But even so, it’s very important that you ask the question. If more and more consumers start asking where their fish comes from, that will lead to better labeling. We have seen initiatives in Europe where some fish is labeled, with catching area and the fishing boat, but of course that’s only a very small share. We would like to see that happening with the whole of the seafood market”.
Plenty of food for thought there, for anyone who eats fish as well as the industry that brings it from the ocean to the table.

UNESCO acknowledges Arctic site
Tsá Tué, Courtesty of UNESCO
I registered that UNESCO had added 20 sites to its World Network of Biosphere Reserves during a meeting in Lima, Peru, in March. It escaped my notice, though, that one of them was in the Canadian Arctic. Thanks to @polarkatja on Twitter, I found out that Tsá Tué in Canada’s Northwest Territories was one of the new sites added to the list this year.
I have been trying to find out the background, and exactly what that means for the area and the small community of people who live there.
The area includes Great Bear Lake, which is described by UNESCO as “the last pristine Arctic lake”. I would like to know exactly what criteria are used to come to that conclusion, but have drawn a blank so far. It is the largest lake located entirely in Canada, covering an area of 12,000 square miles, on the edge of the tree line and hundreds of miles from large centres of population. It’s on the Arctic circle, and is said to be covered with ice from late November to July. (Normally, or hitherto, I should probably say. Who knows how long that will be the case with the Arctic warming so fast).
According to the brief description I found on the UNESCO website, the Taiga that covers much of the site is important to wildlife species including the muskox, moose and caribou.
The only human residents in the site are the Sahtúto’ine (The Bear Lake People), a traditional First Nation Dene Déline people (whose name means “where the water flows”). Their community of 600 is established on the western shore of the lake, where they live off harvesting and limited tourism activity.
It seems they must have been doing a fine job combining ecological and environmental concerns, which is why they have been added to the UNESCO list. It seems fair to say the sites on the list are sort of best practice examples. These are sites of global importance to both biological and cultural diversity and, together, they represent an almost full range of the planet’s ecosystems, according to the UN body.
UNESCO Biosphere Programme
UNESCO created its “Man and the Biosphere Programme” (could it perhaps be time to switch to “Humankind…?”) in the 1970s as an intergovernmental scientific programme to improve the way people in different parts of the world live with their natural environment. Biosphere reserves are supposed to be places to learn about sustainable development and reconciling the conservation of biodiversity with the sustainable use of natural resources. Not an easy task.
The total number of biosphere reserves is now at 669 sites in 120 countries, including 16 “trans-boundary” sites. New reserves are designated each year by the International Coordinating Council of the Programme, which brings together elected representatives of 34 UNESCO Member States.
Biosphere, SDGs and Paris Agreement
This year, the 4th World Congress of Biosphere Reserves ended on 17 March in the capital city of Peru with the adoption of a Declaration and a new ten-year Action Plan.The Lima Declaration sets out to promote synergies between Biosphere Reserves and the United Nations’ 2030 Sustainable Development Goals and the Agreement on Climate Change, adopted in Paris in late 2015. Clearly, none of these agreements can function in isolation.
The text recommends a “wider and more active role” for local communities in the management of the reserves and the establishment of “new partnerships between science and policy, between national and local governance, public and private sector actors.” It also calls for greater involvement of citizen groups and organizations, notably indigenous and youth communities and stresses the need for collaboration with scientific institutions such as universities and research centres. It is not hard to see that remote communities in the Arctic are a fine place to implement this.

Threat from pollution and climate change
The Deline settlement is on the Great Bear Lake, near the headwaters of the Bear River. There is an ice crossing from Deline to the winter road on the far side of the Great Bear River. It seems there was an accident there just last month (March 2016) when a tank truck fell partway through the ice road, just a few days after the government had increased the allowed maximum weight limit to 40,000 kg (88,000 lb) on the road. The truck was loaded with heating fuel for the community, and the accident close to the community’s fresh water intake as well as a major fishing area. This would seem to illustrate the problems human settlement can cause for a key nature reserve area. In fact, it was possible to remove the fuel from the truck.
In terms of sustainable economic activities, today, the lake is a popular destination for people interested in fishing and hunting. Apparently, the largest lake trout ever caught by angling was caught here in 1995. One tourism website advertises the exclusivity of the region, saying only 300 anglers are allowed to fish every year.
In the past, though, mining has been carried out in the region, with uranium, silver and copper in evidence.
As well as climate change, possible mineral, oil and gas and mining exploration put additional pressures on the Lake region, says the UNESCO designation. “Local community elders and leaders worked for many years to develop environmental stewardships,” it says. Being added to the list is an acknowledgement of their commitment, and a way of increasing awareness of the continuing need to protect the area against these threats. The Yorkton News notes that the designation does not carry any legal protection for the land or restrict local decision-makers. “Its purpose, according to the Canadian Biosphere Reserves Association, is to share best practices and make it easier to conserve ecosystems without damaging residents’ ability to make a living on them”.
My congratulations to those who have succeeded in getting the region onto the UNESCO list. And I sincerely hope it will help you continue to restrict human influence on this key area and give encouragement to all those fighting to protect the Arctic on all levels. For that, though, they would have to know about it. So, Iceblog readers, now you have heard a little about it, let’s spread the word.

A letter from Svalbard’s dwindling sea ice
The Arctic sea ice has reached its maximum winter extent for this season, and it was a record low, as reported here on the Iceblog.
The Greenpeace ship the Arctic Sunrise is currently sailing in the Hinlopen Strait in the Arctic archipelago of Spitsbergen, checking out the ice conditions. Larissa Beumer is on board. I wanted to know what the ice situation was like, and she sent me this report. Photographer Nick Cobbing is also on board, so that means we can have a couple of his wonderful pics on the Iceblog. Thanks Nick and Greenpeace.
LARISSA BEUMER: “The ice conditions up here vary considerably from year to year. But this year is really extreme. On the west coast, almost none of the fjords are frozen up. The only exceptions are Dicksonfjord and Van Mijenfjord (and that one isn’t frozen up as far as it “normally” is).
On the east coast, there is no solid, stable ice, frozen through like it normally is. The ice there is moving a lot, it has often broken apart and been blown together again by the wind, so it’s not reliable. (And in general there is less ice there as well).
That means tourists and locals are very severely restricted in their activities. Dog sled and snowmobile tours normally mainly use the frozen-over fjords on the west coast. But this year, a lot of the usual main routes are not usable. That means some of the main destinations like Pyramiden (and Isfjord radio) can only be reached by taking major detours over the glacier systems. The east coast is another of the main destinations for snowmobile excursions. You can still get there quite well, but driving over the ice is more risky than usual. (One tourist group went through the ice this season, but nobody was hurt).
We sailed north along the west coast, then east along the north coast to the Hinlopen strait. We didn’t encounter any large stretches of ice masses anywhere on route. Normally, there is so much ice up there in winter that the route is only navigable from June or July.
Actually, in “normal” years, the pack ice extends down from the north to the northern coast of Spitsbergen right into summer. Now it’s just the bginning of April and the pack ice only starts much further north. Sailing to Nordaustlandet is normally still challenging in August, because of the ice conditions. This year, it’s more or less navigable already. It used to be that expedition cruises billed as “Circumnavigation Cruises” had to change their route because the ice in the north was still so thick they couldn’t get through. I think at the moment you could already do a circumnavigation without any problems.
The ice we can see is mainly fresh ice, one-year ice, with open water here and there and a lot of breaks in it. As I said before, it’s moving about, breaks and is pushed together again. As far as we can see, the thickness is relatively varied, but there is a lot of thin ice amongst it.
The current ice chart from the Norwegian Meteorological Institute shows that a lot of ice from the south has been pushed into the Hinlopen Strait by the wind over the last two days. All this ice just wasn’t there a few days ago. It comes from the pack ice in the north-east, towards Franz-Josef-Land. So it’s not ice that formed here.
So, all in all, it seems fair to say that this year the ice conditions up here around Svalbard are catastrophic and way outside of normal variation. Oscar, our polar-bear guide, says he has never experienced anything as bad as this in the 13 years he has being living here.”
