Arctic oil – still in the picture
Was it too good to be true? The euphoria over the US administration’s moves to protect the Arctic National Wildlife Refuge was dampened somewhat when, just two days later, it released a long-term plan for opening coastal waters to oil and gas exploration, including areas in the Arctic off Alaska. The plan excludes some important ecological and subsistence areas from potential drilling, but it still includes some Arctic areas, including parts of the Beaufort and Chukchi Seas.
Margaret Williams, managing director of WWF US Arctic Programs, told Deutsche Welle, she welcomed in particular the decision to protect the biological hotspot of Hanna Shoal from risky offshore drilling. The Hanna Shoal is a key site for walruses and other animals.
But she stressed other areas of the US Arctic were still subject to oil exploration. The new program will not affect existing leases held by Shell in the Chukchi Sea. The company’s efforts have been the subject of controversy, not least since the grounding of the drill rig Kulluk.
Williams says the problem with the new proposal in general is that it “keeps drilling for oil in the US Arctic offshore in the picture”. With the US poised to take the helm of the Arctic Council, she called for protecting biodiversity to be a top priority for all Arctic nations.
Oil: valuable asset or liability?
It comes as no surprise that Alaskan state politicians and the oil industry promised to fight planned restrictions, saying they were harmful to the economy. But this brings us back to the question of whether the search for new oil in the Arctic makes any sense at all at a time when oil prices are at a record low and the USA is producing plentiful supplies of shale gas.
Bloomberg financial news group quotes financial experts as saying the world’s biggest oil producers do not have “bulletproof business models”, and cites financial cutbacks by BP, Chevrol and Shell:
“The price collapse hobbles a segment of the industry that had already been struggling with years of soaring construction costs, project delays, missed output targets and depressed returns from refining crude into fuels”, analyst Anish Kapadia told Bloomberg.
Conservation groups stressed the need for a different focus, in the year when the USA has pledged to help create an effective new world climate agreement in Paris in November.
“Rather than opening more of the Arctic and other US coastal waters to drilling for dirty energy, the US needs to ramp-up its transition to a clean energy future. As the Administration works to rally international leaders behind a bold climate pact in 2015, decisions to tap new fossil fuel reserves off our own coasts sends mixed signals about US climate leadership abroad, ” said WWF’s Williams.
We know the Arctic is being hit at least twice as fast as the global average by climate change. The ecosystem is already under huge pressure. The Arctic itself is in turn of key importance to global weather patterns. And burning more oil would exacerbate the situation even further.
“We would like to think that we can shift our energy paradigm to clean energy so that we don’t have to take every last bit of oil out of the earth, especially out of the oceans”, said Jackie Savitz from the Oceana Campaign croup.
Studies by the group and by WWF indicate that developing renewable energy technologies such as offshore wind could create more jobs than hanging on to fossil fuel technologies.
Oil spill concern
In addition to the climate paradox of the hunt for new fossil fuels, environmentalists are concerned about the possible impact of an oil spill. Their opposition is not limited to the Arctic. Proposals to open up large areas of coastal waters including some parts of the Atlantic for the first time have also aroused anxiety about possible pollution. But the Arctic is of particular concern because of its remoteness, harsh weather conditions and seasonal ice cover, which is not likely to disappear soon even with rapid climate change:
“Encouraging further oil exploration in this harsh, unpredictable environment at a time when oil companies have no way of cleaning up spills threatens the health of our oceans and local communities they support. When the Deepwater Horizon spilled 210 million gallons of crude oil five years ago, local wildlife, communities and economies were decimated. We cannot allow that to happen in the Arctic or anywhere else,” said WWF expert Williams.
White House senior counsellor John Podesta justified the ban on oil exploration in the ANWR by saying “unfortunately accidents and spills can still happen, and the environmental impacts can sometimes be felt for many years”. The question is – why should this only be applicable in certain areas? Campaigners say it also applies to the other areas now designated by the administration as “OK” for exploration. For the Arctic in particular, limiting exploration to remote offshore areas does not protect the region against the risk of environmental disaster.

Climate worry grows at Arctic Frontiers
I have followed the past two days, the political section of the Arctic Frontiers conference, with great interest, with the thought of the Paris climate conference in November always at the back of my mind.
Clearly, in a country rich from the sale of oil, cutting climate-killing emissions is a tricky issue. The oil sector was strongly represented here, but so too were those who see the need for a transition away from fossil fuels in the interests of the global climate.
With climate change opening the Arctic to development and the search for the oil, gas and minerals thought to be locked beneath the icy region, this year’s Arctic Frontiers meeting has attracted record participation. The impact of low oil prices on development prospects, and political tensions between Russia and western Arctic states have heightened interest in listening to what experts and decision-makers have to say on the relation between climate and energy.
With prime ministers from Norway and Finland and other ministers from Sweden and Denmark, as well as the US special Representative for the Arctic and the Russian President’s special representative for international polar cooperation addressing the meeting, media interest is high in this Arctic city, two hours flight north of the Norwegian capital, Oslo. (Looking at my flight schedule, I see Oslo is actually closer to Frankfurt than to the Arctic north of the country).
Do we need Arctic oil in a warming world?
The Norwegian premier Erna Solberg was here for the presentation of a report on sustainable growth in the north, a joint venture by Norway, Sweden and Finland. Gas is one of the four drivers named in the report. She left no doubt about her country’s continuing interest in oil and gas exploitation in the Arctic region. She told me in a brief interview she sees no contradiction between this and attempts to reach a new world climate agreement in Paris at the end of the year:
“’We have an oil and gas strategy. There are many not yet found areas where we think there is more gas. We think gas is an important part of a future energy mix, and I think we have to explore to find it.”
The same day, the Norwegian government allocated new licenses for exploration in the north-western Barents sea area of the Arctic. Many of the blocks released for petroleum licensing are close to the sea ice zone that had previously been protected. The zones have now been redefined. Conservation groups are upset. WWF Norway says the announcement is risky, as there is still a lack of knowledge about species and ecosystems in this area.
Will low oil price halt Arctic energy development?
With oil prices at a record low, environmentalists hope Arctic development will slow down or even be put “on ice” permanently. Representatives of WWF told the delegates in Tromso – including high-ranking representatives of major oil companies Statoil and Rosneft – the world does not need oil from the Arctic. And gas should be only a “transition fuel”. Samantha Smith, leader of the ngo’s Global Climate and Energy Initiative, quoted the recent study indicating that 50% of the world’s remaining gas and 30% of the oil must stay in the ground if the two degrees centigrade target for maximum global temperature rise agreed by the international community is to have any chance of being adhered to. She presented an alternative vision of “a thriving green economy in the white north”, with renewable energies replacing the search for oil and gas.
Business rethinking fossil investment?
As I wrote here on the Ice Blog after the Sunday evening opening, it is not only the environment lobby that is advocating a switch to renewable enerergy. Jens Ulltveit-Moe, the CEO of Umoe, one of the largest, privately owned companies in Norway, active amongst other things in shipping and energy, said with the current low oil price, Arctic oil was simply not viable, and this would remain the case for many years to come. And by then, he said, the EU’s climate targets and the international support for a two-degree target would make fossil fuels a non-option.
But Sjell Giæver, Director of Petroarctic and Tim Dodson, Norwegian Statoil’s Head of Global Exploration, insisted short-term price drops alone would not halt Arctic exploration. The region was the last place to discover large new reservoirs to satisfy continuing high demand for oil and gas for an increasing world population.
Oil ventures in the Arctic have not been particularly successful in recent years. Statoil’s Dobson admits the biggest ever exploration drilling programme in the Barents Sea last year had a disappointing outcome. Statoil and others have also withdrawn from the hunt for oil off the coast of Greenland.
Russia hungry for Arctic energy
But the Russian President’s Special Representative for International Cooperation in the Arctic, Arthur Chilingarov, who is also a Member of the Board of Directors at the Russian oil giant Rosneft, stressed the company had completed construction of the northernmost well in the world last September. He said a new oil and gas field has been discovered and the program of Rosneft for 2015 to 2019 provided for a large volume of prospecting and drilling in the western part of the Arctic.
One factor however that is slowing Russian activity the Arctic is the implementation of sanctions by European countries and the USA on account of the tensions over Ukraine. Russia has turned to China and other countries for help, but the lack of western technology is an obstacle to further development in a region where bad weather, ice, remoteness and complete darkness in the winter months make oil and gas development a risky business.
There is a clear tendency amongst those involved in Arctic cooperation to play down the sanctions and keep political tensions out of the region. Norwegian President Solberg told me: “We have a good relationship in the Arctic Council with Russia. We have said we will be in line with Europe on sanctions, although Norway is one of the countries hit most by the counter-sanctions from Russia, for instance the fact that oil and gas exploration are among the sanction areas.”
But in the meantime, on a day-to-day basis, cooperation continues, for instance in the joint management of fish resources, said Solberg.
Business as usual?
While the debate continued in the political section of Arctic Frontiers, a new, business strand of the conference opened in parallel. It focuses – on oil, gas and minerals. Olav Orheim from GRID Arendal, a centre that works with UNEP, stressed that a lot of people here are in favour of Arctic oil and gas exploration, in the interests of jobs and economic benefits.Yet after the publication of last year’s IPCC report and with climate change high on the international agenda, there seems to be a wider acceptance here in Tromso of the disconnect between burning fossil fuels and the ever more urgent need to reduce greenhouse gas emissions.
Gunnar Sand is Vice President of SINTEF, the Norwegian “Foundation for Scientific and Industrial Research”, which has close ties to the oil business. From a moral point of view, “we all want to stay below the two degree limit”, says Sand. But it is not possible to change a society and an infrastructure based on fossil fuels overnight.
Technical progress too slow to stop warming
Technology for renewable energy is still not developing fast enough, says Sand. Emission reduction scenarios also rely heavily on carbon capture and storage (CCS), which would reduce emissions from fossil fuel burning and bridge the transition to a low-carbon economy. But the technology, which he himself has been involved in, is moving too slowly. I first met him during a visit to Svalbard, when he told me about a carbon capture and storage project, designed to capture emissions from Longyearbjen’s power station underground. He confirmed in Tromso that it has never been put into action.
Global warming, Sand says, is the most serious challenge of our time. This has to be reflected in political priorities. Governments have to create economic incentives to speed up change.
US special representative ex-Admiral Robert Papp indicated dealing with climate change would be one of the key policy drivers when the USA takes over the Chair of the Arctic Council, the international body that coordinates Arctic affairs, in April.
The Chair of the US Arctic Research Commission Fran Ulmer says a carbon tax would be the best way forward, to encourage industry and consumers to save energy and cut emissions. But she acknowledged the reluctance of governments to impose decisions that could upset their voters at the next election. That is the reality we face as countries weigh up their pledges for the November climate conference in Paris.

A good haul for polar night team
The Polar Night cruise will come to an end on Tuesday, when the last of the scientists will leave the ship with their samples. I was able to stay until the end of the week, when I left the ship at Ny Alesund with some of the researchers, who were changing places with colleagues. I have left Svalbard, but not the Arctic. More about my current whereabouts later.
A good haul in the polar night
It was interesting to hear that our scientists were happy with their “catch”. Sören Häfke, the German scientist from the Alfred Wegener Institute in Bremerhaven, had more than enough of the little crustaceans calanus finmarchius. When they get back to Germany, they can start their genetic analysis to find how their biological clock works in the dark, Arctic winter. In summer, it is assumed light tells them when to come to the surface to feed and when to go down deeper to avoid predators. But what happens in winter, when it is dark all day long? I will look forward to hearing what they find out.
The Russian team had plenty of interesting sediment samples to look into. The others on board also seemed to be happy with the plankton, crustaceans and small fish they brought in for further research. Marine Cusa was a bit unhappy about the lack of polar cod in the fjord. There seemed to be no shortage of larger Atlantic cod. This is related to the amount of Atlantic water currently present in the fjord, expedition leader Stig Falk-Petersen explained to me. It looks as if Marine will be changing the subject of her Master’s thesis. But I have the feeling it will be no less interesting.
“Life doesn’t stop when the light goes out”
Paul Renaud, a Professor at the University Centre in Svalbard, coordinated the logistics of the expedition on board as well as conducting his own biological research. He is one of those who came up with this Polar Night project. As he sums it up, there is a need to follow up on the few studies done in the last ten years which indicate that there is much more activity in the Arctic ocean in winter than previously thought. This must be triggered by processes other than light. Light is critical for the functioning of the ecosystem, but “it’s not that when the light goes out, everything stops functioning”, Paul told me.
From the samples I was shown under the microscope, I can confirm that there is indeed plenty of life going on. And many of the creatures were carrying eggs.
Climate paradox: easier access – shifting parameters
I asked Paul what was driving the surge of research into the Arctic winter. Firstly, new technology makes it possible to take measurements under the ice, and all year round, when there is no-one up here, he explains. Buoys tethered to the ice are one example. A series of permanent observatories has also been set up in the fjords here, measuring temperature, salinity, oxygen, light, chlorophyll and the movement of plankton. The number of research stations in the region has also increased.
The other major factor is quite clearly climate change. The absence of ice makes it much easier to sail up here, says Paul. Just 20 years ago, this fjord would have been completely covered with ice at this time. Now the sea ice is only found in the far reaches of the fjord. But Paul confirmed my theory that while warming is making access easier, it is also changing the parameters the scientists want to measure. “We are addressing a moving target”, is how he describes it.
Ice, less ice, no ice?
When it comes to forecasting how the Arctic ocean and its ecosystem will react to climate change in the long term, the scientists here say we desperately need more data. The IPCC gives around ten scenarios for how climate in the Arctic could develop, Paul explains. Clearly, if we can rely on predictions that the Arctic will be ice-free in summer from the middle of the century at the latest, that will have certain effects on ecosystems
Some organisms can be very flexible, says Renaud, not breeding for ten years and still continuing their populations. But short-lived organisms that rely on a certain timing of ice or live in the sea ice may well be more seriously affected. But without more information, it is impossible to tell how they will react in the long term.
Along with climate change, increased development is bringing more changes to this once inaccessible region, as discussed many times here on the Ice Blog and in my articles for dw.de. Paul is involved in developing monitoring practices. He stresses this is new territory for economic activities like oil exploration, fisheries, tourism and shipping, and that we urgently need more data on the effect of these activities on sensitive components of the Arctic ecosystems.
Can science keep pace with development?
One question I seek the answer to when I talk to Arctic experts is: can this research keep pace with the speed of the development? The answer depends partly, of course, on how fast that development will be. The Svalbard expert says there will still be sea ice in the Arctic in winter for the foreseeable future, around 100-150 years. That will slow economic activities like oil and gas exploration. “That buys us a little more time”, says the marine biologist. But he sees a huge challenge to identify and monitor the impacts of rapidly growing activities like tourism and shipping.
As I packed up to prepare to leave the Helmer Hanssen at the Ny Alesund research station, Paul was giving his instructions to the scientific team. Some were leaving with me, others staying on for the next section. Coordinating the cleaning of the laboratory and deck areas still well splattered with mud, then the packing up and labeling of the samples and equipment, is a major operation. I thought it better not to whinge about fitting my cameras, recorders and Arctic gear into their bags, which somehow seemed to have shrunk over the past week.
On our last night in dock at Ny Alesund, we were treated (not for the first time this week) to some northern lights, eerily dancing across the black Arctic sky. A wicked wind bit at our faces as we headed once again for the world’s northernmost marine lab. The researchers brought crates of samples. I myself brought a treasure trove of stories, ready to go online. The Arctic in winter is harsh but has a charm of its own. It was fascinating to experience the Polar Night, but I was looking forward to my next Arctic destination a bit further south, venue for the major Arctic conference: Arctic Frontiers.
I am now in Tromso, Norway’s “Arctic capital”, where the sun will be reappearing above the horizon this week and the magic pink, pale blue, silvery grey and white Arctic light is already in evidence for several hours a day.

How adaptable are Arctic ecosystems?
The man in charge of this scientific cruise is Stig Falk-Petersen, Professor at the Arctic University of Norway in Tromso and research advisor at Akvaplan-niva, a research consultancy working on environment monitoring. Originally from the Lofoten islands, he is a fountain of knowledge on marine life but also on history, especially relating to changes in the Arctic and indeed the European climate in general. He makes climate history of warm and cold periods more understandable by relating it to events like the Napoleonic wars, or the battle of Stalingrad. He stresses how that kind of approach shows just how important the climate is to society. He also knows a lot about the history of Arctic research. We owe a lot to Russia, where most of the Arctic research came from for a long time, says Stig.
Filling the winter gaps
I had a long talk with him, getting the background to this whole Polar Night project, which started in 2012. Apart from Nansen’s famous ice drift with the Fram (currently being repeated, but that’s a story for later), and the Russian North Pole drift stations, there had been few expeditions to the Arctic ocean in winter. Especially with regard to the southern part of the Arctic Ocean and the Fram strait, there were (and still are) huge gaps in our knowledge, Stig told me. In 2012 conditions were right for winter expeditions to the north and north west of Svalbard, to study the ecosystems. This was to complement a set of permanent observatories set up in the fjords here, measuring temperature, salinity, oxygen, light, chlorophyll and the movement of plankton.
Easier access through climate change?
I wanted to know why this has become possible. Is it because of climate change? Stig told me we actually have a climate record from 1550 until today about the ice around Spitsbergen, going back to accounts of Dutch whalers, which cover around 150 years, then to British expeditions. Since 1979 we have satellite records. All of this shows a large variation in the ice cover. Around 1680, he says, the whole of Spitsbergen was actually ice free. This lasted until 1800, when the ice expanded again from 82 degrees north to 76 degrees north – a huge and fast expansion of the ice cap. Then all this area was ice cold until approximately 1939. Since the year 2000, the region where we are now has been open again. “So you have this large variation of ice cover, driven by various climate factors, – temperature, pressure system, and that means a dramatic change for animals living in this area”, says Stig. To him, this shows the ecosystem up here is able to adapt to considerable change.
Ice, less ice, no ice?
“If you look back 50 years, this was all ice covered, so there was no primary production, so there were very few of these marine animals. Now, since the ice has retreated, the year 2000 approximately, we have a huge bloom of phytoplankton in the spring. So we have nutrients there, and we see that the calumus species, which is important for whales, is there. The bowhead whale, which was more or less extinct in this region for 150 years, is now back”. So, clearly, there are some winners – at least temporarily – in the course of climate change..
Our expedition leader was involved in one research project which could indicate that even some ice- dependent creatures have their own ways of coping with ice-free spells. He and his colleagues found that some tiny creatures which eat off the ice algae under the ice, float out with the ice. When it melts in summer in the Fram Strait, the egg-carrying females migrate down into the North Atlantic current, which then flows up into the Arctic Ocean, then migrate upwards in the water again. “Exactly when the ice algae blooms, in March April, their offspring is back and feeding again,” says Stig. So does that indicate that ecosystems here in the Arctic are well able to adapt to large variations in the climate, I want to know. Stig is reluctant to make anything that could be interpreted as a prediction of what future climate change could hold in store for the High North. But he stresses the temperature has increased in the Arctic by 2 degrees since 1987, much higher than the global increase. His impression is that the ecosystem has adapted well even to such a huge change in a short period. He doesn’t see himself as an optimist. But this view is certainly more optimistic than a lot of other people I talk to about the Arctic.

Ice and mud, glorious mud
Most of the time our ship is out of range of internet connectivity, so this post will be delivered to you from the research base Ny Alesund. My hosts and the station staff were kind enough to arrange a special little boat and a survival suit for a trip through the dark but fascinating polar night. This is only possible because tonight we are still relatively close, with the ship collecting samples in Kongsfjorden, on the north-west side of Spitsbergen. This is an open fjord with a relatively free connection to adjacent shelf. It’s 20 km long, between 4 and 10 metres wide and a maximum depth of 400 metres. This means it is largely influenced by both Atlantic water and Arctic water. It also gets a discharge of fresh water and sediments from adjacent glaciers, which we will be looking at more closely in the next few days. It has been an action-packed day today, watching polar marine night researchers in action. Night research during the day sounds odd, but I can assure you it is certainly dark enough –at any time of day.
Muddy secrets Sergei Korsun from St. Petersburg university and PhD student Olga Knyazeva were out on deck preparing a box corer, a big box-shaped instrument to go down to the seabed and bring up samples of sediment. The teamwork between scientists and crew seems to work brilliantly. The crew operate the lifting and lowering equipment and all sorts of other gear. The scientists collect their samples from it and take them in to the ship’s lab.
“Just a load of mud”, quips Sergei, and there is certainly plenty of it sploshing about in the course of the operation. No wonder there are no outdoor shoes allowed inside.
Olga drains off the water so that only the sediment is left. These two are interested in foraminifera or forams, one-celled organisms. Ice Blog readers may remember I discussed them here some time ago, in connection with research on ocean acidification. German scientists actually wrote a children’s story with Tessi and Tipo, two of these tiny ocean creatures, as the main characters. The focus there was on how increasingly acid seas are dissolving the protective shells of many organisms, especially in cold, Arctic water, where the process is faster. Every creature counts! So why should we be interested in these forams in particular? No question about it, says Olga. There are so many of them, they account for a huge proportion of biomass and we know far too little about what they are up to in the winter. Given their important role in the ecosystem, what they do in winter is something we really ought to know. The season of winter is just too long to be ignored any longer, says Olga. And ultimately, even the tiniest creatures play a role in the global foodweb. Sergei mentions another reason why climatologists and those interested in the history of the planet are so interested in these tiny creatures. They fossilize, so that scientists can use samples from the seafloor to get a record of earth’s history that goes back a very long way.
Inner clocks without daylight? Shortly afterwards, I joined Sören and Lukas from Germany’s Alfred-Wegener Institute for one of their four-hourly net-dropping exercises. For this, a big hatch is opened on the laboratory deck. This brought added excitement as there were a lot of beautifully shaped chunks of ice just floating past. Iceblogger’s delight!
We could also see the hills in silhouette in the background. Clearly there are indeed many shades of “dark”. Seagulls are following us constantly. No doubt they know fish and shrimps are being caught and are always on the lookout for an easy, tasty morsel. In this climate, I don’t blame them. And it is kind of reassuring to have their company, bright in the ship’s lights against the dark sky and sea. The wind felt icy, but the experts up here tell us it is actually relatively mild. Anyway, our two scientists dropped a longish thin net attached to a sort of circular hoop out the hatch, sampling the water.
When it came in, they take samples of small jellyfish, copepods and krill, for a fascinating project to find out about the “biological clock gene”. How can some marine organisms migrate vertically in a 24-25 hour cycle, without light to trigger this? More about that when I’ve interviewed the experts over the next couple of days.
The advantages of winter If you have been waiting for the answer to the question about reproduction in the last blog, I won’t keep you in suspense any longer. Given that the reason is unlikely to be an ideal food supply for the “babies”, some of the scientists on board think the reason could be that there fewer predators about to eat the young, if they arrive in winter. Does that seem plausible? The next post may be a day or two in arriving, as the ship will be out of range from tomorrow onwards. But I promise plenty more to come as soon as we are back in internet range. (How on earth did we live without it?!)
