Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...
Few studies have examined the partitioning of organic matter in upwelling systems,
despite the fact that these systems play a key role in carbon and nitrogen budgets in the
ocean. We examined the production and partitioning of phytoplankton-derived organic
matter in deck incubations off Oregon during the upwelling season. During...
The purpose of this thesis is to provide a first look at the spatial and temporal distributions of dissolved organic material (DOM) off the Oregon coast of North America. While this paper is not a comprehensive examination of these distributions, several patterns are identified as promising candidates for continued research....
Air compressors are a significant industrial energy user and therefore a prime target for industrial energy audits. The project goals were to develop a software tool, AIRMaster, develop a methodology for performing compressed air system audits, and conduct field audits to refine the methodology and assess savings potential from six...
Wideband tunnel-diode amplifiers using common-base
transistor stages for isolation were investigated for
stability criteria, frequency response, and the effects
of temperature and voltage supply fluctuations. For the
first time the full frequency spectrum of a tunnel-diode,
from d-c to the gigahertz (GHz) range, was able to be
utilized in an...
