Canada’s GHG reductions and carbon offsets to prevent warming beyond 1.5 °C need to be reported internationally in order to be recognized in global negotiations around climate change. With growing local and national scale interest in wetlands as a Nature-based climate Solution, improved estimates of wetland organic carbon (OC) sequestration and GHG flux across wetland types are required.…

Intensive agricultural lands feed into Canada’s Great Lakes. The primary type of nitrogen used in agriculture has changed over time, shifting from organic to inorganic forms, such as urea. This change has corresponded with an increase in the frequency, magnitude, and duration of phytoplankton blooms, including cyanobacteria that are known to produce toxins harmful to life.…

Cyanobacteria, algae that form on the surface of nutrient-rich waters, can produce an array of toxins. Accurately measuring these toxins in waterbodies is crucial because they can pose risks to human health and other biological communities. Unfortunately, monitoring and research of these toxins has focused almost exclusively on one particular compound—microcystins.…
