Plans for Arctic universities in the works
Researchers were in northwestern Ontario over the weekend spilling diluted oilsands bitumen and crude oil into a lake to study how the ecosystem, from microbes to fish, responds.
The pilot project, known as Freshwater Oil Spill Remediation Study, is being done at the International Institute for Sustainable Development Experimental Lakes Area southeast of Kenora, Ont.
Vince Palace, the scientist who is leading the experiment, said the area is typically known for experiments involving a whole lake, but this work is different.
“We’re using small enclosures to contain that oil,” he said.
The oil was spilled inside four yellow floating boomed rectangles, each along 2.5 metres of shrub and sphagnum moss shoreline.
The enclosures stretch 10 metres into the lake and contain 20,000 litres of water. Curtain-like sides extend down and are carefully affixed to the lake bottom with lines of sandbags filled at the local gravel pit and placed by a small army of students in waders and wetsuits.
The spills were 1.25 litres each and were to be left for 72 hours then cleaned up by professional oil-spill responders.
With any oil spill, even after clean up, there is residual contamination.

the impact of residuals,” Palace said in an interview before the experiments were conducted.
Palace’s team will study impacts on microbes, algae, zooplankton, insects, wood frogs, and fathead minnows by sampling soil, water, and sediment before and after the spill and clean up.
They’ll look for direct impacts from fouling and poisoning, but also indirect effects on fish survival and reproduction.
Palace notes that when oil spills, social pressure and regulatory commitments create a huge drive to clean it up.
“The problem is, in the shoreline environment, when you spill oil, often times the removal of it can be just as damaging as the impact of the oil on the shoreline environment itself,” he said.
Soil removal, compaction, and moving heavy equipment into
remote areas are ecologically destructive.
“In marine environments, there are microbes present that will |respond to the presence of oil to degrade it. So it may be that there is a benefit to leaving the oil in place to degrade,” Palace said.
The researchers hope to find out if such oil-eating microbes exist in the freshwater environment of oil-naive Boreal shield lakes.
The world’s only northern nation without some form of Arctic university may soon have three of them.
There are plans in all three of Canada’s territories to give their residents a better shot at higher education. Yukon, the Northwest Territories and Nunavut all have different approaches but similar goals.
All want to give their youth a chance to learn without having to travel thousands of kilometres. All want to focus on the needs of their particular jurisdictions. And all believe the North has characteristics — from language diversity to climate change — that could make an Arctic university a draw for students and researchers from around the globe.
“We have a lot to offer,” said Caroline Cochrane, the N.W.T’s minister of education.
The idea of a northern university has been kicked around since at least 2007 when a pan-territorial survey found residents wanted more influence over Arctic research. Northern First Nations have been asking for one for 50 years. Arctic colleges offer northern students degree programs such as education and nursing. But the programs are run and degrees awarded by southern institutions. Now, northerners are taking control of their own post-secondary education. Yukon is likely to be first out of the academic gate.
