Increased benthic grazing: An alternative explanation for low phytoplankton biomass in northern San Francisco Bay during the 1976-1977 drought
F.H. Nichols
1985, Estuarine, Coastal and Shelf Science (21) 379-388
Among the consequences of extremely low river flow into northern San Francisco Bay during a two-year drought were (1) a gradual increase in salinity, (2) an unusual decline in chlorophyll a concentration, and (3) the upstream migration of estuarine benthic invertebrates to the normally brackish area of the bay. Total abundance in...
Elemental X-ray mapping of agglutinated foraminifer tests: A non- destructive technique for determining compositional characteristics.
R.F. Commeau, Leslie A. Reynolds, C. W. Poag
1985, Micropaleontology (31) 380-386
The composition of agglutinated foraminiferal tests vary remarkably in response to local substrate characteristics, physiochemical properties of the water column and species- dependant selectivity of test components. We have employed a technique that combines a scanning electron microscope with an energy dispersive X-ray spectrometer system to identify major and minor...
Toxicity of the lampricides 3-trifluoromethyl-4-nitrophenol (TFM) and 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73) to eggs and nymphs of the mayfly (Hexagenia sp.)

The new International Geomagnetic Reference Field (IGRF) model of the main geomagnetic field for 1980 is based heavily on measurements from the MAGSAT satellite survey. Assessment of the accuracy of the new model, as a description of the main field near the Earth's surface, is important because the accuracy of...
An oxygen buffer for some peraluminous granites and metamorphic rocks.
E. Zen
1985, American Mineralogist (70) 65-73
The mineral assemblage biotite-garnet-muscovite-magnetite-quartz and its sub-sets are common in many peraluminous granites, schists and gneisses. If the biotite and garnet are reasonably iron-rich, then the system is a useful buffer for fO2. Available thermochemical data indicate that, in T-fO2 space, the buffer curve is located between the hematite-magnetite curve...

Charging a variable transit-loss rate for delivery of winter water stored in Pueblo Reservoir has resulted in better management...
A study of the depth of weathering and its relationship to the mechanical properties of near-surface rocks in the Mojave Desert
D.J. Stierman, J. H. Healy
1985, Pure and Applied Geophysics PAGEOPH (122) 425-439
Weathered granite extends 70 m deep at Hi Vista in the arid central Mojave Desert of southern California. The low strength of this granite is due to the alteration of biotite and chlorite montmorillonite. Deep weathering probably occurs in most granites, although we cannot rule out some anomalous mechanisms at...
