Late Holocene Lake-level Variation in Southeastern Lake Superior: Tahquamenon Bay, Michigan
Geomorphic and sedimentologic evidence for the separation of Lake Superior from Lake Michigan and Huron
A common break was recognized in four Lake Superior strandplain sequences using geomorphic and sedimentologic characteristics. Strandplains were divided into lakeward and landward sets of beach
Reconstructing paleo lake levels from relict shorelines along the Upper Great Lakes
Shorelines of the upper Great Lakes include many embayments that contain strandplains of beach ridges. These former shoreline positions of the lakes can be used to determine changes in the elevation
Recent water level declines in the Lake Michigan-Huron system.
Examining water level data representing Lakes Michigan and Huron to evaluate changes in both long-term and seasonal patterns over time, and explore relationships with candidate predictor variables found an underlying lake level decline beginning in approximately 1973 and continuing to the present.
Constraining Holocene lake levels and coastal dune activity in the Lake Michigan basin
Sediment cores collected from embayed lakes along the east-central coast of Lake Michigan are used to construct aeolian sand records of past coastal dune mobility, and to constrain former lake levels
Variability of Lake Michigan water level during the past 1000 years reconstructed through optical dating of a coastal strandplain
Post Nipissing-phase strandplains of the Great Lakes reflect late-Holocene water levels that are linked to climate variability, glacial isostasy, and changes in basin hydrology. This study examines a
Preliminary Report of Late Holocene Lake-level Variation in Southeastern Lake Superior Part II: Tahquamenon Bay, Michigan
ABSTRACT The internal architecture and age of development of 71 beach ridges in the Tahquamenon Bay embayment,located along the southeastern shore of Lake Superior on the Upper Peninsula of Michigan,
Recent Water Level Declines in the Lake Michigan-Huron System
Great Lakes water levels have fluctuated over thousands of years. High water levels were a problem in the 1980s, but a recent sudden drop in Lakes Michigan and Huron has caused particular concern, in
Hydroclimatic factors of the recent record drop in Laurentian Great Lakes water levels
Abstract An extreme low-water supply episode from 1997 to 2000 resulted in the largest 1-yr drop in Lakes Michigan–Huron and Lake Erie water levels (0.92 and 1.03 m, respectively) recorded since


Beach-ridge development and lake-level variation in southern Lake Michigan
Water levels in Lake Ontario 4230–2000 years B.P.: evidence from Grenadier Pond, Toronto, Canada
Lake Ontario water levels have been rising for the past 11 500 years due to differential isostatic rebound of the St. Lawrence outlet. Small scale fluctuations in water level superimposed on this
Postglacial Uplift Predictions and Historical Water Levels of the Great Lakes
Recent uplift of Manitoulin Island, Ontario

  • Environmental Science, Geology
  • 1970
Differential postglacial uplifting in the Huron basin has long been recognized from the observed deformation of raised shorelines, particularly those associated with the Algonquin series of glacial
Stratigraphy of the Sixteen Mile Creek lagoon, and its implications for Lake Ontario water levels
The sequence of units (from the base up) in the Sixteen Mile Creek lagoon (Lake Ontario) mimics the longitudinal sequence of surficial environments: pink silt—overbank (flood plain – dry marsh);
Glacial isostatic deformation of the Great Lakes region
Tilting of ancient shorelines of the Great Lakes region has been studied for more than a century. Nevertheless, fundamental disagreements exist among both glacial geologists trying to understand the
The Rise and Fall of Eustasy
Techniques that can be used to determine the relative magnitude of eustatic excursions include the measurement of: (a) the amount of sedimentary onlap onto the continental margins; (b) the thickness
Present and postglacial rates of uplift for glaciated northern and eastern North America derived from postglacial uplift curves
Average rates of postglacial uplift reach a maximum value of nearly 4 m 100 y−1 over southeastern Hudson Bay, and another high cell, with rates of about 2.5 m 100 y−1, lies between Bathurst Inlet and
Lake Michigan water levels and the development of Holocene beach-ridge complexes at Two Rivers, Wisconsin: Stratigraphic, geomorphic, and radiocarbon evidence
Two beach-ridge complexes formed at Two Rivers, Wisconsin, on the west shore of Lake Michigan during the past 5700 yr. Auger drilling, closely spaced vibracoring, and subsurface geophysical profiling
