Acknowledgments
This large and complex project required the efforts of many individuals and organizations
working closely together in partnership.
The majority of funding for this project was provided by
LTV Steel Mining Company through an agreement with the Minnesota Pollution Control Agency.
The project was coordinated through the Department of Natural Resources. This report
represents the completion of Contract No. 64 under Master Agreement No. M8110 between the
Minnesota DNR and the University of Minnesota, Carl Richards, Principal Investigator.
Jeff Stollenwork and other staff of the Minnesota Pollution Control Agency provided
assistance in securing funding for this project.
Additional funding for this project was provided by the
Minnesota Sea Grant College Program of the University of Minnesota through a grant to
Karen Yin and Carl Richards.
The U.S. Geological Survey, Biological Resource Division, Great Lakes Science Center, Lake
Superior Biological Station, in Ashland WI furnished survey vessels and crews for the
study. Jim Selgeby co-developed initial project scope and design and oversaw field
operations. Gary Cholwek supervised collection of all field data, logistical support,
planning, and assisted in project design and instrument selection throughout the study.
Elmer Hendrickson skillfully piloted the R/V Siscowet through the potentially hazardous
waters during the 1996 field data collection season. Tim Edwards and Keith Peterson did an
exemplary job in rigging survey equipment on the vessels, standing computer data
collection watches aboard the R/V Siscowet, and in skillfully steering data collection
transects with both the R/V's Siscowet and Daphnia.
Don Schreiner of the Lake Superior Fisheries Office of the Minnesota Department of Natural
Resources in Duluth acted as project coordinator and was instrumental in all phases of
project design, completion, and interpretation of survey data.
Karen Yin and Xing Li, (Department of Chemical Engineering, University of Minnesota,
Duluth), and John Bonde developed the substrate classification methods used in this study.
Don Goltz of the U.S. Army Corps of Engineers, Detroit Distict, Duluth Office, provided
invaluable assistance in the completion of technical tasks during several crucial aspects
of the project and provided survey vessels during validation testing. Randy Lundgren and
Ed Parzych assisted with data collection and vessel operation.
John Bonde, Connie Host, Gerry Sjerven, and Paul Meysembourg, of the Natural Resources
Research Institute spent innumerable hours developing and integrating the data needed for
the map creation and in editing the many maps and visuals for this report.
Jeff Stollenwork and other staff of the Minnesota Pollution Control Agency provided
assistance in securing funding for this project.
