Antarctic ice sheet; computer animations and paper model
Tau Rho Alpha, Alan K. Cooper
1998, Open-File Report 98-353-A
This report illustrates, through computer animation and a paper model, why there are changes on the ice sheet that covers the Antarctica continent. By studying the animations and the paper model, students will better understand the evolution of the Antarctic ice sheet. Included in the paper and diskette versions of this...

Effect of restrictive harvest regulations on survival and recovery rates of American black ducks
Charles M. Francis, John R. Sauer, Jerome R. Serie
1998, Journal of Wildlife Management (62) 1544-1557
Population management of waterfowl requires an understanding of the effects of changes in hunting regulations on harvest and survival rates. Mean survival and recovery rates of American black ducks (Anas rubripes) were estimated during 3 periods of increasingly restrictive harvest regulations: 1950-66, 1967-82, and 1983-93. From the first to the...

Magnitude and frequency of floods in Washington
S. S. Sumioka, D. L. Kresch, K.D. Kasnick
1998, Water-Resources Investigations Report 97-4277
Annual maximum instantaneous discharge data for 527 gaging stations with at least 10 years of peak-discharge record on unregulated streams were used to compute the magnitude and frequency of floods on Washington streams. Flood magnitudes having exceedance probabilities of 0.5, 0.1, 0.04, 0.02, and 0.01 were related to physical and...
Optimization of ground-water withdrawal in the lower Fox River communities, Wisconsin
J.F. Walker, D. A. Saad, J. T. Krohelski
1998, Water-Resources Investigations Report 97-4218
Pumping from closely spaced wells in the Central Brown County area and the Fox Cities area near the north shore of Lake Winnebago has resulted in the formation of deep cones of depression in the vicinity of the two pumping centers. Water-level measurements indicate there has been a steady decline...
The Pu‘u ‘Ō‘ō-Kūpaianaha erruption of Kīlauea, November 1991–February 1994: Field data and flow maps

Wide-angle seismic constraints on the evolution of the deep San Andreas plate boundary by Mendocino triple junction migration
J.A. Hole, B. C. Beaudoin, T.J. Henstock
1998, Tectonics (17) 802-818
Recent, wide-angle seismic observations that constrain the existence and structure of a mafic layer in the lower crust place strong constraints on the evolution of the San Andreas plate boundary system in northern and central California. Northward migration of the Mendocino Triple Junction and the subducted Juan de Fuca lithospheric...
Conspecific reproductive success and breeding habitat selection: Implications for the study of coloniality
Etienne Danchin, T. Boulinier, M. Massot
1998, Ecology (79) 2415-2428
Habitat selection is a crucial process in the life cycle of animals because it can affect most components of fitness. It has been proposed that some animals cue on the reproductive success of conspecifics to select breeding habitats. We tested this hypothesis with demographic and behavioral data from a 17-yr...
