Annual and Spatial Variation of the Kelp Forest Fish Assemblage at San Nicolas Island, California
R.J. Cowen, James L. Bodkin
1993, Conference Paper, Third California Islands Symposium
The kelp forest fishes of San Nicolas Island, California were studied from 1981-1986 to examine the causes of among-site and among-year variation in the fish assemblages. Fish counts and seven physical and biological variables were recorded at six sites around the island every spring and fall. Over the study period,...

Analysis of the seismic origin of landslides: Examples from the New Madrid seismic zone
R.W. Jibson, D. K. Keefer
1993, Geological Society of America Bulletin (105) 521-536
By analyzing two landslides in the New Madrid seismic zone, we develop an approach for judging if a landslide or group of landslides of unknown origin was more likely to have formed as a result of earthquake shaking or in aseismic conditions. The two landslides analyzed are representative of two...
Strontium isotopic evidence for a higher water table at Yucca Mountain
Brian D. Marshall, Zell E. Peterman, John S. Stuckless
1993, Conference Paper, High Level Radioactive Waste Management
At Yucca Mountain, calcite occurs as open-space fillings and coatings on fractures within much of the host volcanic rocks in both the saturated and unsaturated zones. Strontium isotope analyses of these calcites divide the samples into two groups corresponding to their location in either the saturated or unsaturated zones. The...
Geological applications of multi-response permutation procedures
L.A. Orlowski, W.D. Grundy, P.W. Mielke Jr., S. A. Schumm
1993, Mathematical Geology (25) 483-500
The multi-purpose permutation procedures (MRPP) test statistic is designed to analyze multivariate data at the ordinal or higher levels. It is based on the weighted averages of symmetric distance functions over all paired objects within a priori disjoint groups of objects from a finite population of objects where each object's...
1:100,000-scale Counties of the United States
U.S. Dept of Commerce Bureau of Census
1993, Report
This is a coverage of the county boundaries of the conterminous United States (AK, HI and Puerto Rico are available separately). The lines were extracted from U.S. Census TIGER/line files using an AML program (see 4.), written by Doug Nebert and Mark Negri, running on two Data General 6220 servers....

Survival in pond water of four reoviruses isolated from aquatic animals
Yolanda J. Brady, John A. Plumb, J. R. Winton
1993, Journal of Applied Aquaculture (2) 85-92
The viabilities of golden shiner virus (GSV), chum salmon virus (CSV), oyster reovirus 13P2 (13P2). and catfish reovirus (CRV) were compared following viruses incubation in pond water samples held at 4°. 20°, 25°, and 30°C for one month. At the three higher temperatures tested, viral infectivity was lost by day...

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....
Toxicity and bioaccumulation of waterborne and dietary selenium in juvenile bluegill (Lepomis macrochirus)
Laverne Cleveland, Edward E. Little, Denny R. Buckler, Raymond H. Wiedmeyer
1993, Aquatic Toxicology (27) 265-279
Juvenile bluegill (Lepomis macrochirus) were exposed to waterborne selenium as a 6:1 mixture of selenate to selenite (as Se) for 60 d and to dietary seleno-l-methionine for 90 d. Measured concentrations of total selenium in the waterborne exposure ranged from 0.16 to 2.8 mg/l, and concentrations of seleno-l-methionine...

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...
