This publication gives basic information on choosing your
planting site, selecting the right species for the site, proper planting
techniques, and first-year care. Although you may be buying a tree
to add beauty to your home landscape,trees also serve other important
functions in your landscape.

The stability of a coastal jet and front is investigated using the primitive
equations applied to a continuously stratified flow in geostrophic balance. A linear
stability analysis successfully explains the growth of two modes of instability with
distinctly different horizontal scales. A long-wavelength mode (fastest-growing
wavelength of 0(100 km)) is...

The new varietal trial at SOES was monitored during the growing season and during ripening by David Sugar and Porter Lombard (see Winegrape Variety Trial in Southern Oregon). The 1993 vintage was a late ripening season and not all the varieties developed sufficient maturity for experimental wine production. Tempranillo, Viognier,...
This study relates surface fluxes to remotely sensed variables over well-defined variations of surface wetness and vegetation. The surface fluxes are estimated from repeated Twin Otter aircraft flights at 33 m above the surface after correcting for advection and local storage between the aircraft level and the surface. An extensive...
Squarrose knapweed, introduced from southwest Asia and the Middle East, became weedy in northern California and Utah by the early 1950s. How it
was originally introduced is not known, but its spread in California
and Utah was associated with the trailing of range sheep. Squarrose knapweed grows in the Klamath,...
This is an exhibit made by the Oregon Department of Fish and Wildlife to the Oregon Fish and Wildlife Commission on October 19, 1994. Topics covered include a summary of the 1993/1994 crab fishery, analysis of the use of long-line gear in crab fisheries, and standards for biodegradable twine on...
in a drought, every gallon of water saved
means more crop production. There are many
places in a typical irrigation operation where
water is lost. Here are some prudent management
practices that can conserve water and
possibly make the difference between making
a profit or taking a loss.
Note: These...
Satellite altimetry has previously been used to map the magnitude of the surface eddy variability of the global oceans, but the direction of the time-variable velocities have been more difficult to determine. Here, a technique is presented for resolving both magnitude and direction of residual surface geostrophic velocities at Geosat...
The island of Tahiti, the largest in French Polynesia, comprises two major volcanoes aligned NW-SE, parallel with the general trend of the Society Islands hotspot track. Rocks form this volcanic system are basalts transitional to tholeiites, alkali basalts, basanites, picrites, and evolved lavas. Through K-Ar radiometric dating we have established...

Agropyron spicatum, considered one of the most important native bunchgrasses in British Columbia, western Montana, the Columbia Basin and the area between the Cascades and Sierras and the Rockies, dominated millions of acres of pristine semiarid grass and sagebrush sites. It produced more herbage than all other associated species in...

Preservative treatment of whole, wood-based composite products (mainly panels) has disadvantages; problems largely stem from swelling, strength loss, and incomplete or inappropriate penetration during treatment, and distortion during redrying. Pretreatment of comminuted wood prior to mat lay-up is one alternative, though the addition of chemicals may affect bonding during subsequent...

The divergence theorem in its usual form applies only to suitably smooth vector fields. For vector fields which are merely piecewise smooth, as is natural at a boundary between regions with different physical properties, one must patch together the divergence theorem applied separately in each region. We give an elegant...
The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
Nisin, bacteriocin produced by Lactococcus lactis, Nisin may have the potential to replace (or reduce) sulfiting agents traditionally added to wines to prevent the growth of spoilage lactic acid bacteria. This may be valuable since sulfites are believed to cause toxic responses in sensitive individuals. As a result, the U.S....
The sorbed gases at all four Ocean Drilling Program Leg 139 sites (855, 856, 857, and 858) showed the unmistakable presence of thermogenic hydrocarbons. No indication of abiogenic gas was found. The evidence for the thermogenic hydrocarbons includes elevated contents of higher hydrocarbons (i.e., C₁/[C₂ + C₃] ca. 2-20), δ¹³CCH₄...

We have selected square subareas (110 km on a side) from coastal zone color scanner (CZCS) and advanced very high resolution radiometer (AVHRR) images for 1981 in the California Current region off northern California for which we could identify sequences of cloud-free data over periods of days to weeks. We...
Altimetric data from the TOPEX/POSEIDON mission will be used for studies of global ocean circulation and marine geophysics. However, it is first necessary to remove the ocean tides, which are aliased in the raw data. The tides are constrained by two distinct types of information: the hydrodynamic equations which the...
