Preliminary results of a multidisciplinary study of cores in southwestern Lake Michigan suggest that the materials in these cores can be interpreted in terms of both isostatically and climatically induced changes in lake level. Ostracodes and mollusks are well preserved in the Holocene sediments, and they provide paleolimnologic and paleoclimatic data, as well as biogenic carbonate for stable-isotope studies and radiocarbon dating. Pollen and diatom preservation in the cores is poor, which… 
Hydrologic and climatic implications of a multidisciplinary study of late Holocene sediment from Kenosee Lake, southeastern Saskatchewan, Canada
Sediment lithology and mineralogy, as well as ostracode, plant macrofossil and stable isotope stratigraphies of lake sediment cores, are used to reconstruct late Holocene hydrologic changes at
Stratigraphy of the mid-Holocene black bands in Lakes Michigan and Huron: Evidence for possible basin-wide anoxia
The post-glacial history of the Great Lakes has involved several changes in lake levels throughout the latest Pleistocene and Holocene, resulting from the changing position of the retreating

Post-Chippewa oxygen isotope record from Cowles Bog, southern Lake Michigan basin
Previous studies of sediments and molluscs recovered from vibracores at Cowles Bog, a fen located in the Indiana Dunes National Lakeshore, along the south shore of Lake Michigan, reveal long and
Paleohydrology and paleochemistry of Lake Manitoba, Canada: the isotope and ostracode records
Lake Manitoba, the largest lake in the Prairie region of North America, contains a fine-grained sequence of late Pleistocene and Holocene sediment that documents a complex postglacial history. This
An early Holocene oxygen isotope record from the Olson buried forest bed, Southern Lake Michigan
Analysis of a 3.5 m vibracore from the Olson buried forest bed in the southern Lake Michigan basin provides new paleolimnological data for the early Holocene. The core records a rise in lake level
Stable carbon and oxygen isotope record of central Lake Erie sediments
Stable carbon and oxygen isotope data from mollusc aragonite extracted from sediment cores provide new information on the origin and history of sedimentation in the southwestern area of the central
The history and architecture of lacustrine depositional systems in the northern Lake Michigan basin
The post-glacial history of the Great Lakes has involved changes in lake levels that are equivalent in vertical extent to the Pleistocene changes in global sea level and changes in sediment
Holocene hydrologic and hydrochemical changes of the South Basin of Lake Manitoba, Canada, inferred from ostracode shell chemistry and autoecology
Holocene record of ostracode shell chemistry from the South Basin of Lake Manitoba shows how isostatically and climatically induced changes in the surface and groundwater input to the overall


Stratigraphy, descriptions, and physical properties of sediments cored in Lake Michigan
A total of 55 box, gravity, piston, and vibracores were collected in the southern two-thirds of Lake Michigan in 1988 and 1989. Analyses of these cores reveal the late Quaternary stratigraphy beneath
The effects of late-Quaternary climatic changes and glacioisostatic rebound on lake level fluctuations and benthos of Lake Michigan

Past lake stages of Lake Michigan are the result of water level stillstands and fluctuations initiated by the withdrawal of the Wisconsin glacial ice sheet (approximately 10,000-5000 years before

Two opposing interpretations have been made on the depositional origin of the Late Pleistocene Sunnybrook diamicton in the Metro-Toronto region of southern Ontario. The traditional view holds this
