Dr. Gertrud Nürnberg is an environmental scientist with 30 years of experience studying and modeling the geochemistry of lakes and reservoirs (Ph.D. 1984, McGill University, Montreal, Canada) . She develops models to predict average nutrient concentrations in lakes and reservoirs, including those that are polluted or anoxic (oxygen-free at the bottom). Past experience includes the determination of watershed (external) and sediment (internal) loadings of nutrients and other pollutants, the establishment of lake nutrient objectives and TMDLs (Total Maximum Daily Loads) for municipal and state agencies, and the estimation of anoxia in more eutrophic waters. She is a past Director of the Eastern Canada Region of NALMS (North American Lake Management Society).

Dr. Bruce LaZerte is an environmental scientist with statistical training (Ph.D. 1978, M.A. Statistics 1975, University of Michigan, USA) and has many years of experience studying and modeling the hydro-geochemistry of upland catchments, wetlands and lakes. His research has included the impact of "acid rain" on forested catchments and wetlands, aluminum and acidified soil geochemistry, aqueous toxicology and toxic trace metal geochemistry. He has also developed daily, time-dynamic, mass balance models for nutrients in lakes and reservoirs and studied stable carbon isotope ratios in lake plankton and sediments.

Drs. Nürnberg and LaZerte have studied and modelled hardwater lakes and reservoirs of southern Ontario, Quebec, Alberta, Connecticut, Michigan, Idaho, South Dakota, Colorado, Germany and Sweden as well as softwater lakes, wetlands and upland soils on the Canadian Shield in north-central Ontario and in Finland.
Past projects of Freshwater Research
They have prepared numerous reports for engineering firms, public interest groups, lake associations and municipal, provincial and federal levels of government. In addition, they have authored book chapters and over fifty scientific articles in respected journals such as Environmental Science and Technology, Journal of Environmental Engineering (ASCE), Limnology and Oceanography, Lake and Reservoir Management, Hydrobiologia, Archive of Hydrobiology, Water Research, Water Resources Research, Geochimica et Cosmochimica Acta, and the Canadian Journals of Fisheries and Aquatic Science, Forest Research and Soil Science.
