Research Profile

Dr. Baulch is an aquatic ecosystem biogeochemist with a research focus at the interface between field research and modelling.  Her research interests include water quality, aquatic ecology, global change, biogeochemical cycles, greenhouse gas emissions, and eutrophication.  The overall goal of her research program is to determine how to maintain crucial freshwater ecosystem services in the face of climate change and nutrient pollution.

Current Research

  • Prediction and management of harmful algal blooms
  • Winter limnology: Understanding implications of declining periods of ice cover
  • Characterizing the importance of aquatic ecosystems in regional and global greenhouse gas budgets
  • Catchment nutrient dynamics in agricultural landscapes: improved modelling, characterization of wetland drainage effects, and assessment of beneficial management practices
Helen Baulch discusses her research program at Buffalo Pound Lake. Buffalo Pound Lake is located downstream of Lake Diefenbaker in the Qu'appelle river system. Researchers are studying algal blooms in the lake and using sensor technology that transmits data in real-time to help understand how the lake responds to a warming climate and other environmental changes. This video is part of a larger series exploring the large scale research observatory established by the University of Saskatchewan's Global Institute for Water Security across the Saskatchewan River Basin.
