The Nordic Orion became the first cargo ship to take the treacherous Northwest Passage from the Pacific Ocean to Europe last year, and now its Danish operators are planning more trips across the Arctic as the sea ice melts.
In September 2013, the ship carried 73 500 tons of coal from Vancouver, in Canada, to Finland by cutting directly across the Arctic, shaving about four days off a trip which would normally take it through the Panama Canal and across the Atlantic.
The Nordic Orion is likely to be the first of many ships to use the route as global warming reduces the sea ice.
It is a trend that has caused concern among environmental groups, who are worried about the impact of pollution on the near-pristine Arctic environment. The noise of ship engines cutting through the Arctic Ocean will also irritate the sensitive hearing of sea mammals such as whales.
Researchers are now trying to evaluate the environmental impact that the increasing access will have on the Arctic’s vulnerable ecosystems, so that they can guide policymakers as they seek to regulate the region.
It’s not only the prospect of more ships making the Northwest Passage, but in recent years researchers have also seen an increase in traffic through the Northern Sea Route, which runs between Asia and Europe through Siberian Arctic waters.
‘You may still have key passages or pivotal points where you have large ice masses or blockages, so you may still need icebreakers to get through, though everything else may be open,’ said Dr Michael Karcher, the assistant coordinator of the EU-funded ACCESS project, which is monitoring the region.
‘Our aim is to provide the science, the knowledge that may help in making political decisions.’

The thinning ice also means better access to vast oil and gas deposits believed to be buried under the seabed. The Arctic is estimated to have about a third of the world’s undiscovered natural gas and 13 % of its undiscovered oil, and energy firms have already started drilling into the ice.
The long-term trend is for the sea ice to continue melting due to global warming, meaning the scramble to access these resources will only intensify. However, conditions in the Arctic can vary widely over the next few decades, and that makes it tricky for policymakers to regulate.
That’s why the ACCESS project is focusing on the impact of climate change on oil and gas extraction, transportation and sea life over the next 30 years.
‘We have long-term trends like reduced ice thickness, increased warming and reduced ice extent, but at the same time this overlaps with a very strong natural variability, making it very difficult to make predictions over the next few decades,’ said Dr Karcher.
Increased pollution caused by shipping traffic and oil and gas production has significant implications for the Arctic atmosphere, and could have an impact on climate change itself. To find out what this impact might be, the project is collecting data and measuring concentrations of hydrocarbons and chemical and particle pollution in the region.
The melting ice is also likely to mean more fish farming in the Arctic as higher temperatures provide suitable conditions for expansion, the project said, while there could also be a surge in the number of tourists who want to experience the Arctic before any of its unique characteristics disappear.
However, one of the biggest problems is that of governance, as it is still unclear which countries have jurisdiction over much of the Arctic. That makes it difficult to regulate the region coherently.
ACCESS researchers have been developing proposals for ways to deal with potential disagreements that may happen over jurisdiction or access to resources. For example, various options over marine transport will be put to the Arctic Council and the International Maritime Organization.
By the time it finishes in 2015, the project will pull together its findings into recommendations for policymakers. ‘Our aim is to provide the science, the knowledge that may help in making political decisions,’ Dr Karcher said.
Food waste, garden cuttings, manure, and even human sewage can be turned into solid biocoal for energy generation, and, if scaled up, could help match the industrial demand for carbon with the need to get rid of organic waste and reduce greenhouse gas emissions.
New recycling technologies currently being tested may allow plastics such as single-use food packaging, fibre-reinforced car parts and mattress foam – polymers which often wind up in landfills or are incinerated – to have more than just a second life: they can become as good as new.
In our continuing search for other life in the universe, one place has always looked promising – Mars. It is a rocky planet like Earth, orbiting the same star, and at a distance where water could have been present on the planet.
Moving more goods by water could reduce pressure on roads and cut emissions, yet Europe’s shipping industry is held back by labour shortages. Automated shipping – which would work in a similar way to self-driving cars – could help expand capacity but safety and regulatory hurdles remain.
The red planet may be our best bet for finding out whether we’re alone in the universe.
Reducing crew numbers onboard ships could overcome labour shortages and increase shipping levels.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
