Lab's Research Showcased on the World Stage

Alemu Gonsamo's team in the Remote Sensing Laboratory had reason to celebrate this month.

The lab's two-year research study for World Wildlife Fund Canada was presented at the COP26 United Nations Climate Change Conference in Glasgow, Scotland and made national headlines in the Globe and Mail and CBC.

The Mapping Canada's Carbon Landscape study found that 405 billion tonnes of carbon is stored in Canada's ecosystem. The study, which was supported Maple Leaf Foods and the Metcalf Foundation, is the first-ever comprehensive analysis of its kind and has major implications for conversation planning and strategies.

Camile Sothe, a postdoctoral fellow in Alemu's lab, led the two-year study. "I am incredibly proud of Camile," says Alemu. "Camile led such a challenging project, worked with multiple collaborators, and established a working relationship with the Mushkegowuk Cree First Nations community in Northern Ontario to collect more reference data in the coming years to validate the maps." 

Camile SotheThe research aligned with her academic and personal interests, says Camile. "Being a person who loves nature and works for the environment, I'm glad about the positive impacts of this research when it comes to climate change.

"Quantifying and mapping the carbon stocks of plants and soils in Canada are the first steps for future studies to understand the vulnerability of carbon stocks to human actions such as carbon removal by decomposition, fires, harvesting and other disturbances.

"Having the results shared a conference of such magnitude as COP26 only highlights the critical role Canada plays on a global scale when it comes to climate change."

The study is based on data from existing soil and plant biomass samples collected from across the country, as well as long-term satellite data and topographic and climate variables. 

“Tens of thousands of field measurements were fed into a machine-learning algorithm to train satellite observations, including space-based laser scanning data, to estimate carbon stocks in plant biomass and soils across Canada," says Alemu, Canada Research Chair in Remote Sensing of Terrestrial Ecosystems, an assistant professor with the School of Earth, Environment & Society and a member of the McMaster Centre for Climate Change. "The resulting national carbon map will have a huge impact on the way conservation activities and policies are approached to prioritize nature-based climate solutions."

The research will also play a key role in WWF-Canada's 10-year plan to restore one million hectares of lost complex ecosystems, protect and steward 100 million hectares of ecologically rich habitat and reduce carbon emissions by 30 million tonnes.

“The findings of this study are monumental for conservation in Canada, and across the world," says Megan Leslie, WWF-Canada President and CEO. "Knowing where carbon is stored in Canada allows us to strategically protect and manage the right places to prevent billions of tonnes of carbon from being released into the atmosphere. Protecting these areas will also benefit wildlife by safeguarding habitat for important species at risk.”

The undergraduate students in the Brook Research Group weren't yet born when Faculty of Science Research Chair Mike Brook and research scientist Dan Chen began working together.

Mike hired Dan in 2001 to fill the key role of lab manager. For the past two decades, Dan's supervised dozens of undergraduate and graduate students, supported Mike's work and conducted his own research on synthetic polymers. Mike secures year-to-year funding from industrial partners to cover Dan's salary.

"Research makes me happy and working with students keeps me active and continually renews my knowledge," says Dan. "When I was young, I wanted to become an expert in a small and specific chemistry field. Silicone chemistry is the one for me and Mike is internationally known as a leading expert in silicones."

So what's been the key to a successful 20-year partnership? "Develop mutual respect and make sure both parties are part of the team," says Mike. 

Dan agrees that mutual trust and respect are key. "Mike always fully supports my work, knowing and valuing my contributions to research projects and lab management. Our communications with each other are always open-minded and lead to creative thinking."

20-year celebration for Dan ChenAnd what have they learned from each other?

"I've tried to emulate Dan's amazing ability to stay calm under pressure but it's still a work in progress,"  says Mike. "Fortunately, Dan is a patient teacher."

"I've learned creative thinking skills from Mike and how to deliver effective and engaging presentations to a wide variety of audiences," says Dan. "Mike also leads by example when it comes to staying active both at work and during leisure time." 

Mike and the entire research group held an outdoor appreciation lunch earlier this summer to celebrate Dan's 20 years of service as lab manager.

Professor Co-authors Review of Stable Isotopes

Sang-Tae Kim is among nine international experts who have prepared an authoritative guide for scientific communities who use stable isotopes as a research tool.

Kim, an associate professor with McMaster’s School of Earth, Environment & Society, is the co-lead author of a technical review published this month in the journal Nature Reviews Earth and Environment.

The review provides researchers with a stable isotope toolbox for water and inorganic carbon cycle studies. The review provides the best available parameters and equations for stable isotope geochemistry, as well as essentials of stable isotope analysis.

Stable isotopes of hydrogen, carbon and oxygen are used to investigate physical and chemical processes in water and inorganic carbon cycles on Earth. Measuring and comparing natural isotopic variations requires reliable reference materials and consistent data treatment.

The International Atomic Energy Agency directed the committee in 2017 to review decades of reference materials and recommend guidelines for using isotopic scales and reporting stable isotope compositions.

“Stable isotopes are among the most popular research themes and most widely used tools for many Earth and environmental scientists,” says Kim.  “Our committee’s recommendations on parameters and protocols are timely and important especially for the Earth and environmental science researchers who are conducting climate reconstruction studies and model ling future changes to the Earth’s climate systems.”
