GBF 2021 - Summer Newsletter

Georgian Bay Forever is a community response to the growing need for major research and education to sustain the Georgian Bay aquatic ecosystem and the quality of life its communities and visitors enjoy. We help monitor the Bay’s well being, throughout the seasons, year after year. We fund the research needed to protect the environmental health of Georgian Bay and the surrounding bodies of water. Using our research findings, we inform and educate the general public and governments about threats to environmental health and propose possible solutions. Through workshops, seminars and online, we are educating the Georgian Bay community. By teaming up with reputable institutions, we enhance the credibility of our research and strengthen our ability to protect what’s at stake. Georgian Bay Forever is a registered Canadian charity (#89531 1066 RR0001). We work with the Great Lakes Basin Conservancy in the United States, as well as other stakeholder groups all around the Great Lakes. Deeply rooted and broadly drawn, Georgian Bay Forever is steered by lifelong devotees of the Bay. We are committed advocates, educators, environmentalists, realists, idealists, and of course, residents.

Our deployment of Georgie McBay- Face—our autonomous underwater electric vehicle—also requires transportation to sites via our boat. We all know that powered boats release exhaust gasses into our waters, but what might not be known is that recent research shows that emissions from gas powered marine engines are 38 times those of a small vehicle. A fuel efficient, latest-generation, 5HP 4-stroke engine produces 38 times the emis- sions of a passenger vehicle. A small cruiser sized boat with twin screws produces about 140,000 g/hr CO2 at 3,500 RPM—14 hours of operation produces the same emissions as 100% of the entire annual emissions from a small passenger vehicle. A 4-stroke 150HP outboard motor produces 51,504 g/hr CO2 at 3,500 RPM producing the entire annual single vehicle emissions in 90 hours of operation. Older 2-stroke engines are even worse1 when it comes to fuel efficiency and emissions. Further, these emissions are directly discharged into our waters in lieu of emissions catalyst technologies. The study makes a compelling and distasteful point: “The effect of two-stroke engines on the odour threshold concentrations of water was found to be severe; e.g. a 15 kW (20HP eq) two-stroke engine that operates for 1 h makes 11,000 m3 of water undrinkable.” Clearly there is a nexus for GBF and our wider community in these issues and talking about how to reduce that largely recreational load is important. Our work to protect our water should not be contributing to the contamination of the water. Redesigning or retrofitting emission reduction technologies into gas powered boat engines is unlikely in the face of emerg- ing electrification technologies and trends in marine and automotive industries. Due to our low-carbon energy production in Ontario, a viable alternative is electric propulsion. Therefore, demonstrating these electric options is a useful and productive public edu- cation opportunity and completely within the mandate of GBF in protecting our water. Stay tuned for more on this initiative. 1 Friedrich Jüttner, Diedrich Backhaus, Uwe Matthias, Ulf Essers, Rolf Greiner, Bernd Mahr, “Emissions of two-and four-stroke outboard engines—II.
