Lake Ice hazard Advisory service
Lake Ice is a dynamic and well-known travel hazard but remains poorly studied. NextGen uses climate information, RADAR satellite data, classification and change detection methods to identify, map, and monitor lake ice hazards.
Frozen lakes are common features of our landscape and are an important cultural heritage. It is unfortunate that most people have to learn lake ice safety on their own, step by step, by trial and error. That is the inherent nature of risk. NextGen advocates new technology and education can help to decrease risk by improving the safety of lake ice travel through planning, identification, and monitoring of risk factors. Our services complement your existing best practices for travel on floating lake ice and may extend and improve them.
Why Map Lake Ice Hazards Now?
Our past experience on lake ice is not expected to be a good indicator of the future. This challenges even the experienced as we all head into a new ice regime. A study published recently in Nature Climate Change indicates an extensive loss of lake ice will occur within the next generation. This is not the distant future. Such climate change could have profound effects on many remote communities and the recreational activities of an increasing number of lake ice users as our populations grow. Inter-annual climate variation is superimposed on this warming trend. This means the risks we understand today are likely to increase as the ice conditions that we have become accustomed to change. A new approach is merited to help ease into a warming climate.
NextGen’s experience can help. The risk of collision with rough ice or immersion of property and people can be reduced with planning, identification, and monitoring of specific risk factors that improve best practices for travel on lake ice. Also, there is information about the structure and decay of lake ice held within the scientific community that should be more accessible to those of benefit. Such outreach has not occurred before as it was not possible to create and relay timely and actionable information.
The maturation of RADAR satellite imaging and internet technologies today means we can detect properties of lake ice from space and make this information available in near-real time applications using the web and cellular phones. RADAR images are formed with energy that comes from the satellite. This means imaging can occur at night, through clouds during the day, and using wavelengths that are independent of weather. As the number of RADAR satellites is increasing and with low or no cost for images new and meaningful applications are real.
March 31, 2019 – NextGen completed a study of lake ice hazards funded by the Canadian Space Agency. We studied 84 lakes in Canada for two winters (three consecutive freeze-ups) to break-up, starting in 2016. Ice validation study was completed in smaller areas of the complex ice cover found on the south basin of Lake Winnipeg.
After the novel and successful project, NextGen continues to develop the technology and refined it. We have since refined and applied the new advances in understanding to the challenging ice conditions found at the scale of the southern basin of Lake Winnipeg for the 2018/2019 ice cover period.
