This research consists of two related yet distinct
studies: an observational study of the surface character of
the penetration of marine air into the southern Willamette
Valley and a climatological study of the summertime air
masses of...

Several horizontal flight segments from SESAME and
ALPEX are studied using structure functions and specral
analysis methods. Theoretical analysis of the relative
errors in structure function and correlation function in
the presence of large scale...

An eigenvector analysis of the velocity-temperature correlation
matrix is applied to clear-air turbulence measured by aircraft in the
Bora. The eigenvectors are identified with the main eddies of the
turbulence. This study attempts to infer the...

The perturbation of a stably-stratified flow by irregular
terrain is studied utilizing a seven-layer, hydrostatic, and
potential enstrophy and energy conserving primitive equation
model. The Island of Oahu, Hawaii, and the surrounding ocean area...

The Mars Pathfinder (MPF) arrived on the Martian surface on 4 July
1997 to become only the third successful landed mission to Mars, recording
surface meteorological data intermittently over a period of 83 Martian days
("sols"). The in situ...

The nature and magnitude of experimental errors due to ⁶⁵Zn
adsorption by inorganic surfaces was examined in a laboratory system
designed to measure ⁶⁵Zn uptake by marine phytoplankton. In the pH
range, 6.3±.1 to 7.5±.1, a precipitate formed in...

Techniques for computing gravity anomalies by multipole expansions
obtained from surface integrals and volume integrals are derived
together with a vertical line element method. The results are
compared with exact calculation for right rectangular...

A three component drag probe has been built, calibrated, and
used to measure velocities beneath deep water ocean waves and
turbulence in a tidal channel. Simple variable inductance devices
which may be submerged in water were used as displacement...

Observations were made of salinity, temperature, nitrate +
nitrite, phosphate, silicate, total available nitrogen, and chlorophyll
a in nine areas of the Alaskan Inside Passage during April of 1971.
In general all properties indicated the water to...

The numerical modeling of motions in the atmosphere's
planetary boundary layer (PBL) is a challenging task. In
general, the boundary layer interacts with both the overlying
atmosphere and the underlying land or water surface
in a complex manner....

Moored instrument records, drogue displacements, and hydrographic
observations are used in describing the coastal currents and
upwelling off Peru. The data were obtained over the continental shelf
near 15°S. during a two week study in late March...

Bacteria were isolated from water at Alder Slough, Oregon. Of
15 isolates grown successfully in the medium employed, 100% showed
measurable uptake of Zn-65. A growth curve was established for one
isolate, a gram-negative rod designated AS-1....

Monthly samples of nutrients, phytoplankton and zooplankton
were taken in the Columbia River estuary over a period of 16 months
in order to determine distribution with season and salinity, and interrelationships
between plankton and nutrients....

Research on the application of soluble, metal chelates for
water tracing using thermal neutron activation analysis for tracer
determination has led to the development of several tracers with
promising solution stabilities (conservative behavior)...

Two successive years of wind speed and direction data, from
January 1973 through December 1974, have been measured and
recorded at Yaquina Head, 6 km north of Newport, Oregon. Analysis
of the data permitted 65 cases of strong wind to be isolated...

The stability of steady-state solutions of the equations governing two-dimensional,
homogeneous, incompressible fluid flow are analyzed in the context
of shear-flow in a channel. Both the linear and nonlinear theories are
reviewed and compared. In...
