Precipitation is nearly balanced by evapotranspiration in northern Minnesota (Bidwell et al., ), whereas other peatlands (e.g. Hudson Bay Lowland) are in areas with a moisture by: (1) The hydrogeological setting of the Glacial Lake Agassiz Peatlands in Minnesota was investigated by measuring ground-water levels in observation.

Like its namesake - Louis Agassiz (), the father of glacial geology - glacial Lake Agassiz's influence was felt far and wide. Evidence of glacial Lake Agassiz occurs over an area of roughlysquare miles, an area five times the size of the state of North Dakota, although at no single time did the lake ever cover this entire area.

The white areas shown between bogs and mineral soils are places in the peatland covered by fens. The A-A' line is the transect for the hydrogeologic cross section shown.

The dotted line and. Lake Agassiz was first hypothesized by American geologist William H. Keating in during an expedition in the Great Lakes region. It wasn’t formally noticed by the scientific community untilwhen geologist Warren Upham published, “The Glacial Lake Agassiz” (named after popular glaciologist Louis Agassiz).

In this chapter, research findings from the glacial Lake Agassiz peatlands are used to develop a conceptual framework for peatland hydrogeology and identify four challenges related to northern.

depends both on the material properties of the peat and the evolving hydrogeologic setting of the wetland. is an ideal setting to address the question: under what hydrologic conditions does chemical diffusion or raised bogs in the vast mire of the Glacial Lake Agassiz Peatlands, northern Minnesota, USA, have confirmed that porewater.

The hydrology of a created riparian wetland system was characterized for local and regional conditions. Three methods, two laboratory and onein situ, were used to calculate the hydraulic conductivity of the wetland substrate.

Hydraulic conductivity values and measured vertical gradients were used to estimate seepage loss to ground water. Ruhl, J.F. Hydrogeologic and Water Quality Characteristics of the Red River-Winnipeg Aquifer, Northwestern Minnesota. USGS Water Resource Investigations, WRI Siegal, D.I.

Squares represent locations of soil test holes and triangles. HISTORY OF LAKE AGASSIZ RESEARCH The former existence of an extensive body of water in the Red River valley was first documented by scientific explorers.

Winchell (), who initiated geological surveys for the state of Minnesota, was first to attribute the lake to glacial blockage of northward drainage. Lowell’s paper is one of 14 to be presented Oct. 10 in a session titled: “Glacial Lake Agassiz—Its History and Influence on North America and on Global Systems: In Honor of James T.

Teller.” Although Lake Agassiz is gone, questions about its origin and disappearance remain. Answers to those questions may provide clues to our future climate.

Beaches of Glacial Lake Agassiz Ben Huffman Ashley Russell Appearance Old beaches are traceable Continuous, smoothly rounded ridge Most lie feet above till side, and above lake side Variations in height are due to unequal currents and wave power Some beaches are cut through from old streams Marked by gravel and sand sloping into water level and till Provide.

and Glaser, P.H.87Sr/ 86Sr as a tracer of groundwater discharge and precipitation recharge in the Glacial Lake Agassiz Peatlands, Northern Minnesota, USA, Water Resources Research, vol. 36, p Ground-water flow in extensive peatlands such as the Glacial Lake Agassiz peatland in Minnesota may be controlled by the development of ground-water mounds (elevated water tables fed by precipitation) in raised bogs where ground water moves downward through mineral soils before discharging into adjacent fens (Siegel, ; Siegel and Glaser, ).

In order to assess these opposing hypotheses, we analyzed a 43year data set from the Glacial Lake Agassiz peatlands (GLAP) in northern Minnesota (Figure 1).

The Glacial Lake Agassiz peatlands comprise a km2 expanse of patterned bogs and fens in northwestern Minnesota between 48º 3' and 48º 35' N lat. and 95º 3' to 95º 40' W long. (Figure 1) [Glaser, a].

This study area lies entirely within the lacustrine plain of former. Ground-water flow simulations were constructed to evaluate the interaction between ground water and wetlands systems, focusing on peatlands in the Kenai Peninsula Lowlands, south-central Alaska.

Peatland systems occur in both recharge and discharge zones along transects simulated in computer models, whereas toe slope wetlands occurred in discharge zones. Sensitivity.

Florida is the site of extensive wetlands and peatlands. The organic matter associated with these deposits adsorbs uranium and may act as a local sink depending on its hydrogeologic setting. This work examines the role of organic matter in the distribution of uranium in the surface and shallow subsurface environments of central and north Florida.

In particular, the production and transport of methane, carbon dioxide, and dissolved organic carbon form the deeper portions of these peatlands is unknown. Our DOE research program is to conduct an integrated ecologic more» and hydrogeochemical study of the Glacial Lake Agassiz peatlands (northern Minnesota) to better understand the carbon.

Geographically Isolated Wetlands (GIWs) occur along gradients of hydrologic and ecological connectivity and isolation, even within wetland types (e.g., forested, emergent marshes) and functional classes (e.g., ephemeral systems, permanent systems, etc.).
