Uncertainties in, and interpretation of, carbon flux estimates using the eddy covariance technique

Creator:: Loescher, H. W., Law, B. E., Mahrt, Larry, Hollinger, D. Y., Campbell, J., and Wofsy, S. C.
Abstract:: Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...

Oregon's seafood industry : its importance to Oregon's economy

Creator:: Rompa, William J., Smith, Frederick J. (Frederick John), 1936-, Miles, Stanley, Oregon State University. Sea Grant Marine Advisory Program, and Oregon State University. Extension Service
Abstract:: This publication is one of the first attempts to describe Oregon's seafood industry in economic terms. It draws together information from many local, state, and federal sources. When data were not available, they were developed from basic sources.

Prototyping a triple-layer phoswich detection system

Creator:: Duncan, Christopher L.
Abstract:: Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: 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...

Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Effects of Fertilizer on Media Chemistry and Red-flowering Currant Seedling Growth Using a Subirrigation System

Creator:: Dunlap, Layla J., Pinto, Jeremiah R., and Davis, Anthony S.
Abstract:: Water conservation in nursery systems is an ever-increasing focus, yet there is relatively little guidance for growers producing seedlings intended for restoration regarding how practices such as subirrigation influence plant growth in the nursery and after outplanting. Our study investigated red-flowering currant (Ribes sanguineum Pursh) seedling development and early field...

Some contributions to asymmetric error control codes

Creator:: Elmougy, Samir
Abstract:: In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...
