Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...
For the Army aviator, Night Vision Goggle (NVG) flight in the tactical rotarywing
profile is a very demanding, task saturated environment. Map navigation is just one
of the many tasks that must be accomplished during flight. The dim, monochromatic
lighting required for NVG flight alters map colors, decreases image detail...
GIS technology has reached a point where it can be utilized by nonprofessionals in a desktop environment. This paper reviews the implementation of a pilot project for developing a localized-natural resource GIS. The resulting GIS was custom designed to answer questions posed by fish and wildlife biologists who need to...
The hydrography in the central and east basins of the Bransfield Strait is examined using data collected along a track 340 km long through the strait in November 1995, in conjunction with historical data from the NODC database. Circumpolar Deep Water (CDW) was seen throughout most of the central basin...
A mechanism by which long planetary waves in the ocean may propagate significantly faster than the classical long baroclinic Rossby waves is investigated. The mechanism depends on the poleward thickening of intermediate density layers and the concomitant thinning of near-surface and deep layers. These features of the mass distribution are...
Clark is a hazelnut selection developed by Oregon State University.
Trees of this genotype are about 30 percent smaller than ‘Barcelona’ yet
have comparable yields to ‘Barcelona.’ This selection has good quantitative resistance to eastern filbert blight (EFB).
Harvest is 7–10 days earlier than‘Barcelona’ and nuts are free-husking.
Nuts have...
An approach developed recently to study the dynamics of vorticity defects in homogeneous
shear flow extends naturally to the case of baroclinic, quasi-geostrophic
flow. It is shown that an inviscid geostrophic flow with uniform vertical shear may
be destabilized by introducing a `potential vorticity defect', an arbitrarily small but
sufficiently...
