R.L. Wilby, L.E. Hay, W.J. Gutowski Jr., R.W. Arritt, E.S. Takle, Z. Pan, G.H. Leavesley, M.P. Clark
2000, Geophysical Research Letters (27) 1199-1202
Daily rainfall and surface temperature series were simulated for the Animas River basin, Colorado using dynamically and statistically downscaled output from the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) re-analysis. A distributed hydrological model was then applied to the downscaled data. Relative to raw NCEP output, downscaled...

D.L. Nikitina, J.E. Pizzuto, R.A. Schwimmer, K.W. Ramsey
2000, Marine Geology (171) 7-20
We present an updated Holocene sea-level curve for the Delaware coast based on new calibrations of 16 previously published radiocarbon dates (Kraft, 1976; Belknap and Kraft, 1977) and 22 new radiocarbon dates of basal peat deposits. A review of published and unpublished 137Cs and 210Pb analyses, and tide gauge data...
Seismic anisotropy of the shallow crust at the Juan de Fuca Ridge
J. Almendros, A.H. Barclay, W.S.D. Wilcock, G.M. Purdy
2000, Geophysical Research Letters (27) 3109-3112
Microearthquake data recorded on four ocean bottom seismometers are used to study shear-wave splitting on the Endeavour Segment of the Juan de Fuca Ridge. The covariance matrix decomposition method is used to determine the sensor orientation from explosive shot data and to estimate the anisotropy parameters for 238 earthquake records....
U.S. Geological Survey, remote sensing, and geoscience data: Using standards to serve us all
Michael G. Benson, John Faundeen
2000, Conference Paper, Proceedings of International Geoscience and Remote Sensing Symposium (IGARSS)
The U.S. Geological Survey (USGS) advocates the use of standards with geosciences and remotely sensed data and metadata for its own purposes and those of its customers. In activities that range from archiving data to making a product, the incorporation of standards makes these functions repeatable and understandable. More important,...
The use of earthquake rate changes as a stress meter at Kilauea volcano
J. Dieterich, V. Cayol, P. Okubo
2000, Nature (408) 457-460
Stress changes in the Earth's crust are generally estimated from model calculations that use near-surface deformation as an observational constraint. But the widespread correlation of changes of earthquake activity with stress has led to suggestions that stress changes might be calculated from earthquake occurrence rates obtained from seismicity catalogues. Although...
Simulations of flooding on Tchoutacabouffa River at State Highways 15 and 67 at D'Iberville, Mississippi
Karl E. Winters
2000, Water-Resources Investigations Report 2001-4007
A two-dimensional finite-element surface-water model was used to simulate the effects of the proposed State Highways 15 and 67 relocation on water-surface elevations and flow distributions for the 100-year flood on the Tchoutacabouffa River at D'Iberville, Mississippi. The Mississippi Department of Transportation plans to relocate State Highways 15 and 67...

Discrepancy between earthquake rates implied by historic earthquakes and a consensus geologic source model for California
M.D. Petersen, C.H. Cramer, M.S. Reichle, A.D. Frankel, Thomas C. Hanks
2000, Bulletin of the Seismological Society of America (90) 1117-1132
We examine the difference between expected earthquake rates inferred from the historical earthquake catalog and the geologic data that was used to develop the consensus seismic source characterization for the state of California [California Department of Conservation, Division of Mines and Geology (CDMG) and U.S. Geological Survey (USGS) Petersen et...
Formation and distribution of coal balls in the Herrin Coal (Pennsylvanian), Franklin County, Illinois Basin, USA
P.J. DeMaris
2000, Journal of the Geological Society (157) 221-228
Large areas of concentrated coal balls (permineralized peat) up to 4 m thick obstructed longwall mining in the Herrin Coal at the Old Ben No. 24 mine. The largest coal‐ball area mapped contained >1500 m3; several areas contained >400 m3 of coal balls. In‐mine mapping established that there were two types of roof (freshwater...
Estimation of wave phase speed and nearshore bathymetry from video imagery
H.F. Stockdon, R.A. Holman
2000, Journal of Geophysical Research C: Oceans (105) 22015-22033
A new remote sensing technique based on video image processing has been developed for the estimation of nearshore bathymetry. The shoreward propagation of waves is measured using pixel intensity time series collected at a cross-shore array of locations using remotely operated video cameras. The incident band is identified, and the...
Survival and brood rearing ecology of emperor geese
Joel A. Schmutz
2000, Thesis
Emperor Geese (Chen canagica) breed on the Yukon-Kuskokwim Delta in an area inhabited by three other goose species. Whereas populations of other geese increased since the mid 1980s, Emperor Goose numbers remained low. Because survival and habitat selection by broods of Emeperor Geese had not been studied previously and numbers...
Characteristic length scale of input data in distributed models: implications for modeling grain size
Guleid A. Artan, C. M. U. Neale, D. G. Tarboton
2000, Journal of Hydrology (227) 128-139
The appropriate spatial scale for a distributed energy balance model was investigated by: (a) determining the scale of variability associated with the remotely sensed and GIS-generated model input data; and (b) examining the effects of input data spatial aggregation on model response. The semi-variogram and the characteristic length calculated from...
Diagenesis and reservoir quality of the Upper Mississippian Aux Vases Sandstone, Illinois Basin
Janet K. Pitman, Mitchell E. Henry, Hannes E. Leetaru
2000, Professional Paper 1609
Conventional reservoir quality data for more than 300 wells provided by the Illinois and Indiana state geological surveys were analyzed to determine the factors governing porosity and permeability in the Upper Mississippian Aux Vases Sandstone, an important hydrocarbon-producing unit in the Illinois Basin. In addition, approximately 150 samples of the...
