Helping citizen scientists advance research on climate change by documenting changes in the Far North.
By Christian Aagaard
Ellsworth LeDrew has a scene on his mind.
A party of Inuit hunters sets out from a settlement. One of them stops, pulls out a smart phone and snaps a picture of a crack in the shore ice that affects his route.
The hunter instantly uploads the photo to a public database, which shares the image with anybody who has an interest in ice conditions in the area.
"It’s like a traffic alert on your Magellan,’’ LeDrew says, referring to a popular digital navigator.
LeDrew, a professor in the Department of Geography and Environmental Management at the University of Waterloo, champions the notion that science benefits from the participation of laypersons.
The cellphone laboratory
Too often, he says, cost and professional barriers shut people out of reams of online information. Ordinary, cellphone-toting citizens could be especially useful in tracking the extent and effect of climate change.
Some obstacles are starting to fall.
The Polar Data Catalogue, an online repository of detailed research about the Arctic and Antarctic, is a less forbidding place for visitors without lengthy academic credentials.
As communication networks improve in the Far North, LeDrew sees citizen scientists adding photos of landscapes and weather events to the store of images captured by satellite.
His own first- and third-year students practise with the model. They photograph scenes and events that affect their lives, uploading images to a Google platform set up for their classes.
“What we are trying to do is to transform data into information that people can use,” LeDrew says. “This is where the gap between scientist and citizen is trying to be bridged.”
For researchers, the work of eyes in the sky and eyes on the ground could provide a richer understanding of how climate change affects the land.
For the people of the north, LeDrew says, using and stocking a vast store of Arctic research affords something even greater: Strong information by which they can determine their own social course through a warming environment.
