  • B.Sc. Hons, Carleton University
  • Ph. D., Biological Oceanography, University of British Columbia

Research Expertise and Interests

Marlene Evans main projects focus on contaminants in the environment, particularly fish and sediments. This includes mercury food web studies at a variety of lakes in the western provinces; mercury and persistent organic trends in Great Slave Lake; and mercury focused studies of sea-run char at Cambridge Bay, and mercury studies related to oil sands activities and western mercury emitters. She is also investigating PAHs under various oil sands studies. She is investigating the sensitivity of lakes to acidification from the oil sands with nitrogen emerging as an issue of concern. Evans has interests in basic limnology, ecology and productivity and has been able to develop collaborations based on my current projects which bring value-added components to my collaborator's studies. Overall she is most interested in studies related to protecting northern ecosystems, particularly lakes, from adverse impacts from development and investigating how climate change will affect these systems. Marlene Evans recently have become involved with the Nature Conservancy, including volunteer activities with sites in the southern portion of the province and has become a member of the Saskatchewan Regional Board and is currently looking for opportunities to contribute to NC goals in grassland and other southern areas.
