Research by Region: International - North America

Canada

As might be expected from a Great Lakes oriented institution, GLERL conducts many collaborative research projects with Canadian scientists and conducts research in Canadian waters of the Great Lakes. GLERL has also conducted a number of research projects in Canada's inland lakes.

Projects

Assessments of benthic macroinvertebrate communities in the Great Lakes

Invertebrate Resting Eggs As Secondary Aquatic Invasion Vectors

Real-time Environmental Coastal Observations Network (RECON) Project

Overlake Wind Events on Lake Erie

Sediments of Lake Erie

International Field Years on Lake Erie

Great Slave Lake
The environmental radiotracers project has been part of GLERL's research program for 20 years. It has employed a variety of natural and fallout radionuclides to characterize and model particle transport processes in diverse systems around the world, including Great Slave Lake. It also has provided a practical means for the environmental management community to assess historic impacts of contaminants and nutrients on ecosystems and evaluate proposed remediation strategies.

Lake George
The environmental radiotracers project has been part of GLERL's research program for 20 years. It has employed a variety of natural and fallout radionuclides to characterize and model particle transport processes in diverse systems around the world. It also has provided a practical means for the environmental management community to assess historic impacts of contaminants and nutrients on ecosystems and evaluate proposed remediation strategies.

In Lake George, both Canadian and U.S. Scientists, are collaborating to reconstruct the history of human impacts on the St.Mary's system by measurement of contaminants, nutrients and biological components in dated sediment cores from Lake George. This small lake, fed by the north branch of the St. Mary's River, is situated about 20 km down-river from urban/industrial sources and is ideally suited for the study. Currently this study focuses on historic changes that have occurred in the abundance and composition of diatoms (siliceous plankton), the connection between the trace element bromine and diatom abundance, and the story of chromium contamination.

The Lake George study is a textbook example of the use of dated sediments to identify system contaminants, reconstruct their loading histories and biologic effects, to pinpoint offending sources, to chronicle the beneficial results of environmental regulation and illustrates the possible forensic use of well-placed, high-resolution sediment receptor sites.
