The Arctic in a Pool: Simulator Grows Sea Ice
Researchers collect frost flowers for chemical analysis at the Sea-ice Environmental Research Facility in Winnipeg, Canada.

French photographer Samuel Blanc has been leading tours to Svalbard, Norway's archipelago in the Arctic, since 2007. This year the reduced sea ice extent allowed his expedition aboard the 12-passenger Polaris to circumnavigate the northern islands in early July rather than mid-August. Climate change is having a direct impact on the unique ecosystem isolated on these islands more than 400 miles north of Europe. In the following photos, Blanc gives us a tour of life on the archipelago's largest island, Spitsbergen. You can see more of his work at www.sblanc.com.
In west Spitsbergen, Little Auks, such as those pictured here, and other birds aren't safe on the cliffs. Hungry polar bears have learned to climb the steep gradients in search of food.

The dissolved iron seen in this glacier may help fight climate change. As the iron washes into the northern seas, it can help fertilize phytoplankton blooms that draw carbon dioxide out of the atmosphere.
As global warming melts permafrost in the arctic, more carbon is released into the atmosphere. Meanwhile areas of tundra are also seeing a rise in fires.
The vast stretch of open water due to thinning of the Arctic sea ice is forcing walruses to often crowd together on beaches.
This bearded seal has found a safe spot away from polar bears and sharks. Many seals however also snooze in the water, where they are at risk of becoming of meal for the Greenland shark, the world's slowest shark.
Only three percent of the total population of arctic fox are called "Blue fox" and unlike the rest of the population, these blue critters don't turn white in the winter.
These foxes are showing their summer colors.
This winter, flowers bloomed in the northern Canadian city of Winnipeg. But not the verdant blooms that might come to mind; these were frost flowers.
The University of Manitoba opened a sea ice simulator last year to see how ice forms on the open water of the frigid poles, and how it affects the local climate and plant life.
The $1.5 million Canadian ($1.46 million USD) Sea-ice Environmental Research Facility's 30-foot-long (9 meters) pool — the centerpiece of the project — is where the researchers sprinkle salt, water and environmental contaminants, then watch how the sea ice grows.
The facility runs during the winter, when the outdoor temperature is below 28.9 Fahrenheit (minus 1.7 degrees Celsius), the temperature at which ice forms.
"The real beauty is we can add (chemical or biological) tracers to it and use the sensors to monitor it in real time," said Feiyue Wang, an environmental chemist who leads the facility.
"As an experimental scientist, I always like to do control experiments. What if we hold some variables constant? What if we change them? You can't do that in the Arctic," Wang told OurAmazingPlanet.
Frost flowers are one of the types of ice they can grow at the facility. These structures form around salt on the surface of the ice, and host a wealth of microbes that can survive in harsh Arctic environments. Previous research found that they contain far more salt than the surrounding waters.
"If they can concentrate salt, they can concentrate other chemicals in seawater," Wang said, adding that pollutants would be among the chemicals.
The challenge is trying to track down these structures. In the isolated north, scientists rely on remote sensing from satellites to take their research vessel to the correct location. However, it's difficult to pick out the frost flowers from the surrounding ice. (10 Things You Need to Know About Arctic Sea Ice)
At the facility last year, the researchers watched frost flowers over three days using one particular band of radiation. Their goal was to figure out how to position the sensor to best see the flowers. A paper on the research, led by the University of Manitoba's Dustin Isleifson will be published in a future issue of the journal Transactions on Geoscience and Remote Sensing.
More research papers are forthcoming on acidity in the sea ice environment, as well as how carbon is exchanged with the ice, which would help tease out the effects of climate change from carbon dioxide on the Arctic ocean environment.
Within the next few years, the researchers aim to enhance their "simulation" by taking a sheet of ice from the Arctic and laying it inside the pool to do controlled bacteria studies.
The researchers are also laying the groundwork for a facility expansion that would allow them to study oil spills in the sea ice environment. The first concrete step will be to obtain funding, which the researchers are working on now.
