Monitoring breakup on the Athabasca River, AB (Canada), April 22, 2003
For years, the staff at Alberta Environment would camp out on the bank of the Athabasca River upstream of Fort McMurray, maintaining a 24h vigil, sometimes for weeks, so as to warn the town when big ice runs were headed towards them. Thankfully, now they have an automated monotioring system, pioneered by our research team.
