An Account of Two Decades of Applied Research and Public Education 1969 to 1989
Bahnick, Donald A.; Balcer, Mary D.; Brooke, Larry T.; Call, Daniel J.; Dickas, Albert B.; Lozano, Stephen; MacTaggart, Terrence J.; Markee, Thomas P.; Roubal, Ronald K.; Swenson, William A.; Vaishnav, Dinesh (1989-04-28)The Center for Lake superior Environmental studies (CLSES) was created in the late 1960's, a period of national environmental concern. The founding scientists, from the departments of biology, chemistry, geology and ... -
CHEMICAL EFFECTS OF RED CLAYS ON WESTERN LAKE SUPERIOR - FINAL REPORT
Bahnick, Donald A. (1975)This project is concerned with expansion of the sparse information currently available pertaining to the chemical effects of red clay erosion on western Lake Superior and certain of its tributary streams. A major part of ... -
Determination of LOD and LOQ Values for PCBs and Dieldrin in Water
Lindberg, Carol A.; Bahnick, Donald A. (1990-02)The relative response factor is the slope of a plot of the response ratio (Area of Congener/Area of IS) along the y axis vs a concentration ratio (ng of congener/ng of IS) along the x-axis. If this plot is linear, then ... -
Development of Bioassay Procedures for Defining Pollution of Harbor Sediments
Bahnick, Donald A.; Swenson, William A. (1977)Six sites in the Duluth-Superior Harbor have been sampled. The sites 1 (Allouez Bay area), 2 (Superior Ore Docks area), 3 (Lakehead Transshipment Terminal area), 4 (Superior Sewage Treatment Plant area) and 6 (Minnesota ... -
Development of Bioassay Procedures for Defining Pollution of Harbor Sediments - Project Summary
Bahnick, Donald A.; Swenson, William A.; Markee, Thomas P.; Call, Daniel J.; Anderson, Craig A.; Morris, R. Ted (1980)This research investigates bioassay methods which may be useful in assessing the degree of pollution of harbor sediments. Procedures studied include 96 hr toxicity tests employing Hexagenia limbata, Daphnia magna and ... -
Ecology of Western Lake Superior Region
Markee, Tom; Devore, Phil; Bahnick, Donald A.; Roubal, Ronald K.; Tychsen, Paul (1983)The twin ports of Superior, Wisconsin and Duluth, Minnesota were founded at the head of the world's greatest continuous mass of freshwater.

Effects of South Shore Drainage Basins and Clay Erosion on the Physical and Chemical limnology of Western Lake Superior
Bahnick, Donald A.; Dickas, Albert B.; Horton, Joseph W.; Roubal, Ronald K. (1972)A chemical and geological investigation of Lake Superior waters and sediments is presented. The study area extends from Superior, Wisconsin to Amnicon Point, Wisconsin, a distance of eight miles. Sampling was enacted on ... -
Geochemical Relationships Between Lake Superior and Its Tributary Streams With-in the Superior-Cornucopia Red Clay Province, Wisconsin
Rouubal, Ronald K.; Horton, Joseph W.; Bahnick, Donald A. (1975-11-24)The sedimentation and water quality characteristics of seven Northwestern Wisconsin Lake Superior tributary streams are presented. A large portion of the drainage basins of these streams is located in the Valder's red ... -
TRANSPORT OF TOXIC SUBSTANCES INTO LAKE SUPERIOR BY SUSPENDED SOLIDS
Bahnick, Donald A.; Markee, Thomas P. (1983-10)A primary threat to Great Lakes sport and commercial fisheries arises from contamination problems due to the introduction of certain xenobiotic chemicals in aquatic environments. Of particular concern are hydrophobic ... -
