The objective of this dissertation was to understand the physical mechanisms affecting inversion events in a complex forested mountain landscape. This work was motivated by the long-term studies of climate at the Andrews Forest, short-term studies of vertical temperature, light, wind, and moisture gradient in old-growth trees, and interest in...
This thesis presents the results of a formal evaluation of a new AOGCM, GENMOM, demonstrating its ability to simulate present-day climate and ENSO dynamics. The model is applied to simulate climate for the Last Glacial Maximum, deglacial, and Holocene time periods. The model output is evaluated against the best available...
The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
This paper evaluates Oregon Statewide Planning Goal 5: Natural Resources and Goal 17
Coastal Shorelands, planning programs and makes recommendations for improvement to the
Oregon members of the Columbia River Estuary Study Task Force (CREST). CREST is a
Council of Governments formed in 1974 which includes the local counties, cities...
Native freshwater fish biodiversily is imperiled in Oregon with 36 species
or sub-species listed by the State of Oregon as sensitive, threatened, or endangered, and
9 species or sub-species listed as endangered or threatened under the federal
Endangered Species Act. Understanding and managing biodiversity is critical to its
conservation. Using...
Archaeological investigations can reveal persistent traditions of ethnic
groups. Hawaiians were employed in the fur trade of the Columbia River from
1810 through 1850. The Hudson's Bay Company employed them at Ft.
Vancouver, Washington from 1825 through the end of this period. Data from
the excavations of the servant's village...
The Late Spring Secondary Precipitation Maximum in the
Interior Pacific Northwest results from a complex system of climatic
controls. The Secondary Maximum is most strongly developed over the
high plateau of Oregon immediately in the lee of the Cascade
Mountains. Local topographic
organization exerts strong control
over the magnitude and...
The developmental patterns of five fuel resources located within
the state of Wyoming are examined through time and in relation to
several factors external to the location of the fuels. An historic
description and inventory of the five fuels: petroleum; natural gas;
oil shale; coal; uranium are presented. External factors...
