Euan Reavie

Position and Focus

Dr. Reavie is the Assistant Director for NRRI’s Center for Water and the Environment. Euan and his research team pursue research in applied aquatic studies on freshwater ecosystems, evaluating water quality issues. Routine work focuses on the use of algae as indicators of environmental changes. Their laboratory is fully equipped for research on biological and chemical indicators of water quality, and paleolimnology, the study of environmental trends through the analysis of sediment profiles. Techniques include high-resolution microscopy, digital imaging, laboratory processing and field sampling.

Recent studies include:

    Open project in a new windowGreat Lakes Biological Monitoring: Phytoplankton
    The primary objectives of the Great Lakes phytoplankton program are to: 1) collect phytoplankton from the Great Lakes; 2) identify and enumerate phytoplankton, maintaining quality assurance standards; 3) maintain a database of phytoplankton data; 4) interpret phytoplankton data, including evaluation of long-term trends in phytoplankton and food web dynamics; 5) dissemination of data and interpretations through reports, presentations, peer-reviewed journals and on the internet.

    Long-Term Aquatic Conditions to Inform Delisting Efforts on the St. Louis River

    An open standards data and metadata pipeline for the Natural Resources Research Institute Great Lakes Data

    Open project in a new windowResearch Development Testing and Evaluation Facility for Ballast Treatment in the Great Lakes Region
    The Great Ships Initiative is a innovative collaboration whose objective is to end the problem of ship-mediated invasive species in the Great Lakes-St. Lawrence Seaway System, including through independent research and demonstration of environmental technology, financial incentives and consistent basin-wide harbor monitoring. NRRI`s task in this effort is to develop, test and apply methods to evaluate the effectiveness of candidate treatments systems in their ability to exterminate algae and protozoans.

    St. Louis River Area of Concern Paleolimnology
    One of the action items in the St. Louis River Remedial Action Plan (RAP) Update 2013 is to assess the eutrophication criterion in order to make local recommendations for removing this beneficial use impairment (BUI) to the Area of Concern.

    Great Lakes Environmental Indicators (GLEI) II - Indicator Testing and Refinement
    The GLEI-II project will focus on wetland near-shore conditions of the Great Lakes, and consists of five tasks: 1) Refine coastal ecosystem indicators from previous monitoring programs through calibration against updated landscape/land use information within the entire Great Lakes basin; 2) Test the temporal and geographic integrity of existing Great Lakes indicators; 3) Test and compare analytical techniques to cross-calibrate indicators from concurrent monitoring programs; 4) Evaluate cost-effectiveness of indicators; 5) Implement a data collection, analysis, and reporting system, as well as a map of baseline conditions for the Great Lakes basin based on historical and current monitoring information.

    A Comprehensive Stressor-Response Model to Inform Ecosystem Restorations Across the Great Lakes Basin
    Two maps depicting anthropogenic stresses across the Great Lakes Basin will be merged into a composite map that spans the entire basin.

    Lake of the Woods Paleolimnology Assessment
    Lake of the Woods has been placed on Minnesota`s impaired list for nutrients and eutrophication indicators, so the future of the lake has become a high profile concern for the Ontario and Minnesota governments and the lake`s diverse group of stakeholders. Research recommendations and data gaps suggested that improved coordination of monitoring efforts and the construction of a long-term ecological reconstruction for the lake were logical steps in management of the resource. NRRI`s objective in this investigation is to collect sediment cores and use archived materials to provide long-term trends and trajectories of lake conditions for use in resource management.
