One of the most important resources for journalists are the scientists doing research in the field.
The Great Lakes Environmental Research Laboratory, part of the National Oceanic and Atmospheric Administration, sponsors lots of research on the Great Lakes region.
Some of the recent research has been:
Land Surface Roughness Effects on Lake Effect Precipitation
Short-term water mass movements in Lake Michigan: Implications for larval fish transport.
Classification of annual Great Lakes ice cycles: Winters of 1973-2002
They have over 30 researchers on staff, doing work in many different fields. Much of the studies involve fish and other freshwater ecology and hydraulic modeling.
A list of these researchers, the areas of research, and their contact information is available on this site.
The Great Lakes Research Consortium is another group of researchers that are exploring the same issues.
The consortium consists of over 350 researchers at universities in the Great Lakes Region. These universities include 18 colleges and universities in New York and nine affiliate schools in Ontario.
A full list of all the scientists can be found here, along with all of their contact information.
More information about discipline specific research journals will be coming soon.
