Chemistry of nearshore surficial sediments from southeastern Lake Michigan (Special report no. 57 of the Great Lakes Research Division, University of Michigan) [Ronald Rossmann] on *FREE* shipping on qualifying offers. The surface 3 cms of sediment from samples were taken from Georgian Bay and the North Channel in Continuous echo-sounding was used to characterise and map the sediment distribution. Samples were analysed lor practicle size, major element and trace by: Surficial sediment concentrations (0–2 cm) ranged from to ng/g dry -lake burdens of Hg, used to determine the source of the contamination, were similar for all lakes in the Author: R. L. Thomas. The spatial distribution of biogenic silica (BSi) in the surficial sediments of Lake Michigan is described from Shipek grab samples collected in and gravity cores obtained in

Surficial Sediment Contamination in Lakes Erie and Ontario Data from the Lake Ontario sediment also in- dicated improvement in the degree of contamina- tion by metals. The Lake Ontario 75 th percentiles for nickel (43 µg/g, Table 1), chromium (27 µg/g), and lead (15 µg/g) were all lower than lake-wide average values of 85 µg/g, µg/g, and µg/g, respectively, reported in (Mudroch Cited by: Sand and silt are minor units in the Ontario surficial sediments. The sediment distribution pattern is essentially simple with a natural superposition of sediment units reflecting the glacial and postglacial history of the lake. The inshore region of Lake Ontario is composed of glacial till and by: A recently discovered chlorinated flame retardant, Dechlorane Plus (DP), was reported in air and a sediment core within the North American Great Lakes region. To further reveal the fate of DP in the Great Lakes, 40 surficial sediments from Lakes Erie and Ontario and two additional cores were analyzed using newly available analytical grade DP isomer by: maps of the Great Lakes Basin, depositional areas and circulation patterns follow in Figures , and , respectively. Lake Superior The most upstream of the Great Lakes is Lake Superior. It is the largest, coldest, and deepest of the Great Lakes, with an average depth of metres (USEPA, ).

Surficial substrates and bathymetry of five historical lake trout spawning reefs in near-shore waters of the Great Lakes. Distribution and ecology of lampreys in the Lower Peninsula of Michigan Report of the audit of the Great Lakes Fishery Commission's program of sea lamprey control and research. p. Great Lakes contaminant burden is site-specific, and order-of-magnitude range. Recent innovations such as acoustic profiling can provide high resolution characterization of surficial and sub-bottom sediments (McGee et al., ), and help define the thickness and distribution of disparate sediment types (Caulfield et al., ). This report presents the geophysical and sample data collected from the St. Clair River, May June 6, as part of the International Upper Great Lakes Study, a 5-year project funded by the International Joint Commission of the United States and Canada to examine whether physical changes in the St. Clair River are affecting water levels within the upper Great Lakes, to assess regulation plans for outflows from Lake .

Attached is a copy of the Inner Long Point Bay report which was prepared for release by the Great Lakes Section of this Branch. A survey was carried out in Inner Long Point Bay during to.
