Hydrochemistry of the Mahomet Bedrock Valley Aquifer, East-Central Illinois: Indicators of recharge and ground-water flow
S.V. Panno, Keith C. Hackley, K. Cartwright, Chao-Li Liu
1994, Groundwater (32) 591-604
A conceptual model of the ground-water flow and recharge to the Mahomet Bedrock Valley Aquifer (MVA), east-central Illinois, was developed using major ion chemistry and isotope geochemistry. The MVA is a “basal” fill in the east-west trending buried bedrock valley composed of clean, permeable...
Mammal extinctions, body size, and paleotemperature
T. M. Bown, P.A. Holroyd, K.D. Rose
1994, Proceedings of the National Academy of Sciences of the United States of America (91) 10403-10406
There is a general inverse relationship between the natural logarithm of tooth area (a body size indicator) of some fossil mammals and paleotemperature during approximately 2.9 million years of the early Eocene in the Bighorn Basin of northwest Wyoming. When mean temperatures became warmer, tooth areas tended to become smaller....
Helping the public find information the U.S. Government Information Locator Service (GILS)
E.J. Christian
1994, Journal of Government Information (21) 305-314
As part of the National Information Infrastructure, the U.S. federal government is establishing a Government Information Locator Service (GILS). GILS will identify and describe public information resources throughout the federal government and provide assistance in obtaining the information. It will be decentralized and will supplement other agency and commercial information...
Paleocene floral diversities and turnover events in eastern North America and their relation to diversity models
N. O. Frederiksen
1994, Review of Palaeobotany and Palynology (82) 225-238
This paper uses angiosperm pollen taxon turnover (first and last appearance) and diversity events as metrics to describe the Paleocene floral history of the eastern Gulf Coast; data are from 64 samples and 67 angiosperm pollen taxa. Angiosperm pollen diversity was very low at the beginning of the Paleocene, rose...
The geochemical cycling of trace elements in a biogenic meromictic lake
Laurie S. Balistrieri, J.W. Murray, B. Paul
1994, Geochimica et Cosmochimica Acta (58) 3993-4008
The geochemical processes affecting the behavior and speciation of As, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, V, and Zn in Hall Lake, Washington, USA, are assessed by examining dissolved and acid soluble particulate profiles of the elements and utilizing results from thermodynamic calculations. The water column of this...

David W. Morganwalp
1994, Open-File Report 94-91
The U.S. Geological Survey began the Toxic Substances Hydrology Program in 1982 to study, in an interdisciplinary atmosphere, the fate and effects of toxic substances in the environment. The objective of the Program is to provide the earth-science information needed to prevent or mitigate contamination of the Nation's ground and surface waters. To...

Determination of sediment thickness and volume in Lake Byron, South Dakota, using continuous seismic-reflection methods, May 1992
S. K. Sando, S.W. Cates
1994, Water-Resources Investigations Report 93-4206
A sediment survey to assess the amount and distribution of lake sediment was made as part of a diagnostic/feasibility study investigating the potential for lake restoration of Lake Byron, South Dakota. A high-frequency, continuous seismic- reflection system was used to estimate thickness of sediment, and a global-positioning system was used...
