Geochemical Relationships Between Lake Superior and Its Tributary Streams With-in the Superior-Cornucopia Red Clay Province, Wisconsin
(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 ...
THE EFFECTS OF RED CLAY EROSION ON ORTHOPHOSPHATE LEVELS IN SOUTHWESTERN LAKE SUPERIOR
(1975-05-20)
The effects of the erosion of red clay deposits along the northwestern Wisconsin shoreline area on
orthophosphate inputs into Lake Superior was investigated. Using clay soil and river particulate
samples, exchange ...
Development of Bioassay Procedures for Defining Pollution of Harbor Sediments
(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 ...
TRANSPORT OF TOXIC SUBSTANCES INTO LAKE SUPERIOR BY SUSPENDED SOLIDS
(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 ...
CHEMICAL EFFECTS OF RED CLAYS ON WESTERN LAKE SUPERIOR - FINAL REPORT
(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
(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 ...
Effects of South Shore Drainage Basins and Clay Erosion on the Physical and Chemical limnology of Western Lake Superior
(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 ...
Ecology of Western Lake Superior Region
(1983)
The twin ports of Superior, Wisconsin and Duluth, Minnesota were founded at the head of the world's greatest continuous mass of freshwater. The Laurentian Great Lakes contain about 20% of the world's freshwater resources. ...
Transport of Toxic substances into Lake Superior by Suspended Solids
(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 ...
Development of Bioassay Procedures for Defining Pollution of Harbor Sediments - Project Summary
(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 ...
