The adaptive significance of hatching synchrony of waterfowl eggs
Paul L. Flint, Mark S. Lindberg, Margaret C. MacCluskie, James S. Sedinger
1994, Wildfowl (45) 248-254
We estimated the amount of incubation time that first laid Black Brent eggs received before completion of the clutch. First laid eggs received up to 48 hours of incubation before the last egg was laid in Brent clutches. Waterfowl clutches usually hatch within a period of 24 hours, suggesting that...

Stream-aquifer interactions in the Straight River area, Becker and Hubbard counties, Minnesota
J. R. Stark, David S. Armstrong, Daniel R. Zwilling
1994, Water-Resources Investigations Report 94-4009
The Straight River, in north-central Minnesota, is a trout stream having cold, clear water. The 75-square-mile Straight River watershed contributes flow to the stream. The watershed is underlain by highly transmissive surficial and confined-drift aquifers. Ground-water discharge from these aquifers sustains flow in the Straight River, and the cold water...
Flood discharges and hydraulics near the mouths of Wolf Creek, Craig Branch, Manns Creek, Dunloup Creek, and Mill Creek in the New River Gorge National River, West Virginia
J.B. Wiley
1994, Water-Resources Investigations Report 93-4133
The U.S. Geological Survey, in cooperation with the National Park Service, studied the frequency and magnitude of flooding near the mouths of five tributaries to the New River in the New River Gorge National River. The 100-year peak discharge at each tributary was determined from regional frequency equations. The 100-year...
Annual replenishment of bed material by sediment transport in the Wind River near Riverton, Wyoming
M.L. Smalley, W. W. Emmett, A.M. Wacker
1994, Water-Resources Investigations Report 94-4007
The U.S. Geological Survey, in cooperation with the Wyoming Department of Transportation, conducted a study during 1985-87 to determine the annual replenishment of sand and gravel along a point bar in the Wind River near Riverton, Wyoming. Hydraulic- geometry relations determined from streamflow measurements; streamflow characteristics determined from 45 years...
Lateral movement and stability of channel banks near four highway crossings in southwestern Mississippi
D. Phil Turnipseed
1994, Water-Resources Investigations Report 94-4035
Channel meandering in alluvial streams has caused localized channel instability that has resulted in bridge failure and loss of human life in Mississippi. The U.S. Geological Survey, in coopera- tion with the Mississippi Department of Transpor- tation, conducted a study to develop a better methodology for defining and estimating channel...
Geologic features of the sea bottom around a municipal sludge dumpsite near 39 degrees N., 73 degrees W., offshore New Jersey and New York
James M. Robb
1994, Open-File Report 94-152
The sea-floor of a dumpsite area offshore New York and New Jersey (Deep-water dumpsite 106) was studied using detailed bathymetry, sidescan-sonar images, subbottom profiles, bottom photographs, and bottom-sediment samples. These data show that this continental rise area contains deposits of submarine landslides and pathways of sediment gravity flows. Images of...
Variation in body mass of wild canvasback and redhead ducklings
Jane E. Austin, Jerome R. Serie
1994, Condor (96) 909-915
We assessed variation in body mass of ducklings in single- and mixed-species broods of wild Canvasbacks (Aythya valisineria) and Redheads (Aythya americana) 20-50 days old. Body mass of canvasback ducklings was not affected by year and season (early vs. late hatch date) despite changes in water conditions. Mean body mass...
Hydrologic time and sustainability of shallow aquifers
William Back
1994, Conference Paper, Proceedings of the Water down under 1994 conference
Measurement of water and short intervals of time are coeval events that began about 6000 BC in Mesopotamia. Even though time and hydrology have been intimately entwined, with time terms in the denominator of many hydrologic parameters, hydrology's a priori claim to time has not been consummated. Moreover, time takes...
Quality-assurance results for routine water analysis in US Geological Survey laboratories, water year 1991
T. J. Maloney, A. S. Ludtke, T.L. Krizman
1994, Water-Resources Investigations Report 94-4046
The US. Geological Survey operates a quality- assurance program based on the analyses of reference samples for the National Water Quality Laboratory in Arvada, Colorado, and the Quality of Water Service Unit in Ocala, Florida.

Reproductive ecology of tundra swans on the Arctic National Wildlife Refuge, Alaska
Matthew J. Monda, John T. Ratti, Thomas R. McCabe
1994, Journal of Wildlife Management (58) 757-773
Management of tundra swans (Cygnus columbianus) is hampered by a lack of information on their nesting and brood-rearing ecology. We studied tundra swan nesting and brood-rearing ecology on the Arctic National Wildlife Refuge (ANWR), Alaska, 1988-90. Nest success was 58% (n = 31) in 1988, 83% (n = 36) in...
Comparison of age determination techniques for female northern pintails and American wigeon in spring
Daniel Esler, J. Barry Grand
1994, Wildlife Society Bulletin (22) 260-264
Accurate age-class determination of waterfowl is necessary for studies addressing age-specific effects (e.g., Serie et al., 1992) and age structure of populations (e.g., Raveling and Heitmeyer 1989). Duck ages can be determined in fall by morphological and color characteristics of tertial and tail feathers (Carney 1992); however, these feathers are...
