Hydrology of the North Cascades region, Washington: 2. A proposed hydrometeorological streamflow prediction method
Wendell V. Tangborn, Lowell A. Rasmussen
1976, Water Resources Research (12) 203-216
On the basis of a linear relationship between winter (October-April) precipitation and annual runoff from a drainage basin (Rasmussen and Tangborn, 1976) a physically reasonable model for predicting summer (May-September) streamflow from drainages in the North Cascades region was developed. This hydrometeorological prediction method relates streamflow for a season beginning...
Hydrology of the North Cascades region, Washington: 1. Runoff, precipitation, and storage characteristics
Lowell A. Rasmussen, Wendell V. Tangborn
1976, Water Resources Research (12) 187-202
The time and space distributions of measured precipitation and measured runoff and of spring storage, which is approximately equal to the subsequent summer runoff of snowmelt and stored groundwater, have been analyzed for the North Cascades region of Washington. Neither precipitation nor runoff shows a consistent relationship with altitude, chiefly...

1976, Journal of the Fisheries Research Board of Canada (33) 177-180
The ultimate upper lethal temperature of young-of-the-year lake whitefish, Coregonus clupeaformis, was 26.65 C; this value is closely similar to that reported for yearling bloaters,Coregonus hoyi (26.75 C) and young-of-the-year lake herring, Coregonus artedii (26.0 C)....
Discovery of natural resources
P. W. Guild
1976, Science (191) 708-713
Mankind will continue to need ores of more or less the types and grades used today to supply its needs for new mineral raw materials, at least until fusion or some other relatively cheap, inexhaustible energy source is developed. Most deposits being mined today were exposed at the surface or...
Rapid determination of nanogram amounts of tellurium in silicate rocks
L. P. Greenland, E.Y. Campbell
1976, Analytica Chimica Acta (87) 323-328
A hydride-generation flameless atomic-absorption technique is used to determine as little as 5 ng g-1 tellurium in 0.25 g of silicate rock. After acid decomposition of the sample, tellurium hydride is generated with sodium borohydride and the vapor passed directly to a resistance-heated quartz cell mounted in an atomic-absorption spectrophotometer. Analyses...

Indexes associated with information theory in water quality
S.M. Zand
1976, Journal of the Water Pollution Control Federation (48) 2026-2031
In many biological studies of water quality, a diversity index is calculated in 'bits per individual' by using Shannon's Approximation to Brillouin's Formula. Difficulties associated with such use of Shannon's Formula and its associated parameters are discussed. Recent research has indicated that diversity indexes can be improved if (a) biological...
Aseismic uplift in Southern California
Robert O. Castle, Jack P. Church, Michael R. Elliot
1976, Science (192) 251-253
Preliminary examination of the historic geodetic record has disclosed crustal uplift of 0.15 to 0.25 meter that apparently began around 1960 and has since grown to include at least 12,000 square kilometers of southern California. This uplift extends at least 150 kilometers west-northwestward along the San Andreas Fault from Cajon...

A magnetic method for determining the geometry of hydraulic fractures
J.D. Byerlee, M.J.S. Johnston
1976, Pure and Applied Geophysics PAGEOPH (114) 425-433
We propose a method that may be used to determine the spatial orientation of the fracture plane developed during hydraulic fracture. In the method, magnetic particles are injected into the crack with the fracturing fluid so as to generate a sheet of magnetized material. Since the magnetization of a body...
