Family stability in greater white-fronted geese
Craig R. Ely
1993, The Auk (110) 425-235
I investigated the stability of parent-offspring bonds, and sibling-sibling bonds of neck-banded Greater White-fronted Geese (Anser albifrons frontalis) during winters (September-May) in California and southern Oregon from 1979 to 1989. Geese captured at feeding sites were more likely to be in social groups than those captured at roosting sites. Offspring...
The Klamath Falls, Oregon, earthquakes on September 20, 1993
S.R. Brantley
1993, Earthquakes & Volcanoes (USGS) (24) 104-146
The strongest earthquake to strike Oregon in more than 50 yrs struck the southern part of the State on September 20, 1993. These shocks, a magnitude 5.9 earthquake at 8:28pm and a magnitude 6.0 earthquake at 10:45pm, were the opening salvo in a swarm of earthquakes that continued for more...
Great Basin NP and USGS cooperate on a geologic mapping program
Janet L. Brown, Vidal Davila Jr.
1993, Park Science (13) 6-7
The GRBA draft General Management Plan proposes development in several locations in Kious Spring and Lehman Caves 1:24,000 topographic quadrangles, and these proposed developments need geologic evaluation before construction. Brown will act as project manager to coordinate the IA with time frames, budget constraints, and the timely preparation of required...

Determination of dissolved-phase pesticides in surface water from the Yakima River basin, Washington, using the Goulden large-sample extractor and gas chromatography/mass spectrometer
Gregory D. Foster, Paul M. Gates, William T. Foreman, Stuart W. McKenzie, Frank A. Rinella
1993, Environmental Science & Technology (27) 1911-1917
Concentrations of pesticides in the dissolved phase of surface water samples from the Yakima River basin, WA, were determined using preconcentration in the Goulden large-sample extractor (GLSE) and gas chromatography/mass spectrometry (GC/MS) analysis. Sample volumes ranging from 10 to 120 L were processed with the GLSE, and the results from...

1993, Conference Paper, Oil and Gas and Other Resources of the Wind River Basin, Wyoming; Special Symposium
The environments of deposition of the uppermost part of the Cody Shale and the Mesaverde and Meeteetse Formations of Late Cretaceous age were studied on outcrop in the Shotgun Butte area in the north-central part of the Wind River Reservation. A shoreface sandstone occurs in the lower part of...

Managing the data explosion
Richard P. Hooper, Brent T. Aulenbach
1993, Civil Engineering (63) 74-76
The 'data explosion' brought on by electronic sensors and automatic samplers can strain the capabilities of existing water-quality data-management systems just when they're needed most to process the information. The U.S. Geological Survey has responded to the problem by setting up an innovative system that allows rapid data analysis....
Stratigraphy and oil and gas resources in uppermost Cretaceous and Paleocene rocks, Wind River Reservation, Wyoming
W. R. Keefer, R. C. Johnson
1993, Conference Paper, Wyoming Geological Association special symposium on oil and gas and other resources of the Wind River basin, Wyoming
The Cody Shale and the Mesaverde, Meeteetse, and Lance Formations of Late Cretaceous age and the Fort Union Formation of Paleocene age within the Wind River Reservation contain strata that were deposited during the final major regression of the Cretaceous epicontinental sea eastward across central Wyoming and the ensuing...
Current status and recent dynamics of the Black Brant Branta bernicla breeding population
James S. Sedinger, Calvin J. Lensink, David H. Ward, Michael W. Anthony, Michael L. Wege, G. Vernon Byrd
1993, Wildfowl (44) 39-48
We summarize current knowledge about the distribution of Pacific Black Brant and recent dynamics of colonies, particularly on the Yukon-Kuskokwim (Y-K) Delta, Alaska. About 20,000 nests are required to produce the number of young in the autumn flight using estimates of clutch size, hatching success and gosling survival based on...
Evidence for Holocene stability of steep slopes, northern Peruvian Andes, based on soils and radiocarbon dates
D. C. Miller, P. W. Birkeland, D. T. Rodbell
1993, Catena (20) 1-12
Radiocarbon dating and soil relationships indicate that landscapes in highaltitude glaciated valleys of the northern Peruvian Andes have been remarkably stable during the Holocene. Radiocarbon dates show that deglaciation was underway by 12 ka, and that slopes and alluvial fans at the bases of slopes were essentially stabilized by at...

Intensity and duration of chemical weathering: An example from soil clays of the southeastern Koolau Mountains, Oahu, Hawaii
Mark J. Johnsson, Stephen D. Ellen, Mary Anne McKittrick
1993, Special Paper of the Geological Society of America (284) 147-170
Orographic precipitation on the southern flank of the southeastern Koolau Mountains produces a pronounced precipitation gradient. The corresponding gradient in the intensity of the chemical weathering environment provides an opportunity to address the effects of varying chemical weathering intensity on the composition of clay-size weathering products in soils developed...
Scaling of the critical slip distance for seismic faulting with shear strain in fault zones
Chris Marone, Brian D. Kilgore
1993, Nature (362) 618-621
THEORETICAL and experimentally based laws for seismic faulting contain a critical slip distance1-5, Dc, which is the slip over which strength breaks down during earthquake nucleation. On an earthquake-generating fault, this distance plays a key role in determining the rupture nucleation dimension6, the amount of premonitory and post-seismic slip7-10, and...
Broad-band acoustic Doppler current profiler
Ernest D. Cobb
1993, Flow Measurement and Instrumentation (4) 35-37
The broad-band acoustic Doppler current profiler is an instrument that determines velocity based on the Doppler principle by reflecting acoustic signals off sediment particles in the water. The instrument is capable of measuring velocity magnitude and direction throughout a water column and of measuring water depth. It is also capable...
Calibration of the BASS acoustic current meter with carrageenan agar
A.T. Morrison, A.J. Williams, M. Martini
1993, Conference Paper, Oceans '93: Engineering in harmony with the ocean: Proceedings (Vol. 3)
The BASS current meter can measure currents down to the millimeter per second range. Due to the dependence of zero offset on pressure, determining a sensor referenced velocity requires accurate in situ zeroing of the meter. Previously, flow was restricted during calibration by placing plastic bags around the acoustic volume....
