A detailed biographical sketch of Ralph W. Spitzer (b. 1918), a graduate student of Linus Pauling's and promising academic who joined the Oregon State College chemistry department in 1946. Promoted to Assistant Professor in 1947, Spitzer was nonetheless fired from the OSC faculty in 1949 by President August L. Strand,...
We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
Considerable effort is presently being devoted to producing high-resolution sea surface temperature (SST) analyses with a goal of spatial grid resolutions as low as 1 km. Because grid resolution is not the same as feature resolution, a method is needed to objectively determine the resolution capability and accuracy of SST...
We investigated the export of particulate organic matter (POM) to the ocean by two contrasting small, mountainous rivers, the Umpqua and Eel Rivers, by collecting suspended sediment samples over a range of discharges and analyzing them for a variety of constituents, including organic carbon, nitrogen, biomarkers with distinct biochemical sources,...
During rapid variations of the atmospheric mixing ratio of a trace gas, diffusive transport in the porous firn layer atop ice sheets and glaciers alters the isotopic composition of that gas relative to the overlying atmosphere. Records of past atmospheric trace gas isotopic composition from ice cores and firn need...
A large-eddy simulation study was performed to characterize turbulence in sparse, row-oriented canopies. This was accomplished by simulating a set of heterogeneous row-oriented canopies with varying row vegetation density and spacing. To determine the effects of heterogeneity, results were compared to horizontally homogeneous canopies with an equivalent ‘effective’ leaf area...
The distribution and range of lesser prairie-chicken (Tympanuchus pallidicinctus) has been reduced by >90% since European settlement of the Great Plains of North America. Currently, lesser prairie-chickens occupy 3 general vegetation communities: sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii), and mixed-grass prairies juxtaposed with Conservation Reserve Program grasslands....
Gene regulatory networks are commonly used for modeling biological processes and revealing underlying molecular mechanisms. The reconstruction of gene regulatory networks from observational data is a challenging task, especially considering the large number of players (e.g. genes) involved and the small number of biological replicates available for analysis. Herein, we...
This study seeks to identify key components of structure and growth habit of Schoenoplectus pungens (bulrush) that allow it to thrive in severe environments. Schoenoplectus pungens, an emergent herbaceous plant growing in shallow, high energy freshwater and brackish coastal wetlands, occurs throughout North America and several continents. We observe the...

Scatterometer ocean surface winds have been providing very valuable information to researchers and operational
weather forecasters for over 10 years. However, the scatterometer wind retrievals are compromised when
rain is present. Merely flagging all rain-affected areas removes the most dynamic and interesting areas from the
wind analysis. Fortunately, the Advanced...
Measurements of δ²H and δ¹⁸O in isotope-based field studies have fundamentally
improved our understanding of water flow and transport time scales in soils and headwater
catchments. Until recently, however, technical constraints have limited the temporal
resolution at which water samples could be collected and analyzed. We introduce a new
sample...
While conflict and cooperation in Central Asia are mainly focused on the larger basins
(Amu and Syr Darya) and the implementation of the agreement reached directly after
independence (1991), here an analysis of the history of water-sharing agreements in the
Isfara Basin is presented. The paper reveals that there have...
A systems trial was established in Oct. 2006 to evaluate management practices for organic production of northern highbush blueberry (Vaccinium corymbosum L.). The practices included: flat and raised planting beds; feather meal and fish emulsion fertilizer each applied at rates of 29 and 57 kg·ha⁻¹ nitrogen (N); sawdust mulch, compost...
For the first time in several years, the El Niño-Southern
Oscillation did not dominate regional climate conditions
around the globe. A weak La Niña dissipated to ENSOneutral
conditions by spring, and while El Niño appeared
to be emerging during summer, this phase never fully
developed as sea surface temperatures in...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
Bismuth oxide thin films were deposited by atomic layer deposition using Bi(OCMe₂ [superscript i]Pr)₃ and H₂O
at deposition temperatures between 90 and 270°C on Si₃N₄, TaN, and TiN substrates. Films were
analyzed using spectroscopic ellipsometry, x-ray diffraction, x-ray reflectivity, high-resolution
transmission electron microscopy, and Rutherford backscattering spectrometry. Bi₂O₃ films
deposited...
This article presents a set of recommendations that promote a more nuanced, meaningful accountability policy for English learners in the next authorization of the Elementary and Secondary Education Act. The authors argue that the ESEA reauthorization must strengthen the law's capacity-building purpose so that federal, state, and local leaders support...
Wireless LANs (WLANs) have been widely adopted and are more convenient as they are inter-connected as wireless campus networks and wireless mesh networks. However, time-sensitive multimedia applications, which
have become more popular, could suffer from long end-to-end latency in WLANs.
This is due mainly to handoff delay, which in turn...
The way of slip transformation and strain partitioning at the eastern termination of the Kunlun
fault system remains unclear, and the question of whether this fault system is an important part for
lateral extrusion of Tibetan crust is debatable. The Tazang fault is regarded as the easternmost
continuation of the...
