The Northern Limits of Glacial Lake Algonquin in Upper Michigan
A number of ancient shorelines formed by late-Pleistocene proglacial lakes have been found in eastern upper Michigan. These shorelines delimit several water planes, the uppermost of which is correlated with the Main Lake Algonquin stage. This correlation is based on the continuity of the highest water plane with Main Algonquin shorelines in Wisconsin and Ontario, the strength of the shoreline f...

متن کاملThe Impact of Chicago on Lake Michigan: Results of the Lake Michigan Mass Balance Study
As part of the U.S. EPA’s Lake Michigan Mass Balance Study, a predictive model for gas-phase persistent organic compounds over Lake Michigan has been constructed. Using air temperature, wind direction and atmospheric PCB concentration collected around and over the lake, the model predicts the concentration of PCB congeners (~100) and trans-nonachlor over the lake and gas exchange fluxes. The mo...
متن کاملPaleoecology of a Northern Michigan Lake and the Relationship amongClimate, Vegetation, and Great Lakes Water Levels
We reconstructed Holocene water-level and vegetation dynamics based on pollen and plant macrofossils from a coastal lake in Upper Michigan. Our primary objective was to test the hypothesis that major fluctuations in Great Lakes water levels resulted in part from climatic changes. We also used our data to provide temporal constraints to the mid-Holocene dry period in Upper Michigan. From 9600 to...
متن کاملGenetic structure of lake whitefish (Coregonus clupeaformis) in Lake Michigan
Genetic relationships among lake whitefish (Coregonus clupeaformis) spawning aggregates in Lake Michigan were assessed and used to predict a stock or management unit (MU) model for the resource. We hypothesized that distinct spawning aggregates represented potential MUs and that differences at molecular markers underlie population differentiation. Genetic stock identification using 11 microsate...
