Environmental fate of mercury discharged into the upper Wisconsin River Environmental fate of mercury discharged into the upper Wisconsin River
The authors studied the distribution of Hg in sediments, fish, and crayfish in a 60 km reach of the Upper Wisconsin River that formerly received Hg in discharges from pulp and paper mills. The most heavily contaminated strata of sediments were deposited during the 1950s and early 1960s and buried under subsequent deposits; however, surficial sediments remained substantially enriched at...

Energy budget and prey requirements of breeding lapland longspurs Calcarius lapponicus near Barrow Alaska, U.S.A. Energy budget and prey requirements of breeding lapland longspurs Calcarius lapponicus near Barrow Alaska, U.S.A.
Breeding Lapland longspurs, Calcarius lapponicus, near Barrow, Alaska, have relatively constant energy demands throughout the summer; the average estimated daily energy budgets (DEBs) were 132 and 118 kJ for the male and female. Thermoregulation accounted consistently for one-quarter to one-third of the total DEB. Flight in the male and incubation in the female were major components of...

Finite-difference grid for a doublet well in an anisotropic aquifer Finite-difference grid for a doublet well in an anisotropic aquifer
The U.S. Geological Survey is modeling hydraulic flow and thermal-energy transport at a two-well injection/ withdrawal system in St. Paul, Minnesota. The design of the finite-difference model grid for the doublet-well system is complicated because the aquifer is anisotropic and the principal axes of transmissivity are not aligned with the axis between the two wells. An analytical...

Hydrogeologic and water-quality characteristics of the Red River-Winnipeg aquifer northwestern Minnesota Hydrogeologic and water-quality characteristics of the Red River-Winnipeg aquifer northwestern Minnesota
The Red River-Winnipeg aquifer of Ordovician age occupies a depression in the Proterozoic crystalline bedrock of northwestern Minnesota. The Winnipeg Formation, which underlies the Red River Formation, consists of two units: A lower shaley mudstone and an upper medium-grained sandstone. The Red River Formation consists of a lower dolomitic, dark-gray limestone and upper, slightly less...

Uptake, biotransformation, and elimination of rotenone by bluegills (Lepomis macrochirus ) Uptake, biotransformation, and elimination of rotenone by bluegills (Lepomis macrochirus )
Yearling bluegills (Lepomis macrochirus) were exposed to sublethal concentrations of [14C]rotenone (5.2 μg/l) for 30 days in a continuous flow exposure system and then transferred to clean, flowing water for an additional 21-day depuration period. Rates of uptake and elimination and profile of the rotenoid metabolites in head, viscera, and carcass components were evaluated by 14C...

National water summary 1984: Hydrologic events, selected water-quality trends, and ground-water resources National water summary 1984: Hydrologic events, selected water-quality trends, and ground-water resources
Water year 1984 was a year of extreme hydrologic conditions. For the third consecutive year, precipitation and resulting runoff were well above long-term averages in most of the Nation and as much as 400 percent above average in the Southwest. National flood damages during the year were the third highest in a 10-year period (1975-84) an estimated $3.5 to $4 billion. In many of the larger...

Trends in municipal-well installations and aquifer utilization in southeastern Minnesota, 1880-1980 Trends in municipal-well installations and aquifer utilization in southeastern Minnesota, 1880-1980
Water distributed by municipal systems has been the largest off-stream use of water in southeastern Minnesota for the past 100 years. Water pumped by these systems in 1980 totaled 102.3 billion gallons, with 60.1 billion gallons supplied by ground water. Ground water supplies 294 of the 309 municipal systems in the area. The development of ground-water supplies for municipal use in...
