Seasonal mountain snowpack of the western US (WUS) is a key water resource to millions of people. Impurities at the snow surface directly affect snowmelt timing and rate, as they contribute to earlier peak streamflow, snow disappearance, and less water availability in dry months. Predicting the locations, timing, and intensity...
Snow is a critical component of global climate regulation and provides water resources to over one billion people worldwide. Yet current measurement methods and modeling techniques lack the ability to fully capture snow characteristics such as snow water equivalent (SWE), snow depth, and density variable landscapes. In recent years, the...
Five simulated precipitation patterns characteristic of the Columbia
Basin and Plateau region and six fertilization rates were evaluated

Studies were conducted over a 10-year period to determine the feasibility
of supplementing lactating cows being wintered on native meadow hay. The
interaction between cow feed levels and creep feeding of calves was also investigated.
Results show that a full feed of meadow hay to the cows and no creep...
The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...
Worldwide, networks of plants and pollinators are faced with the threat of climate change. The extent of this threat and the degree of adaptability is not yet understood. In Oregon, climate change is predicted to bring hotter and drier summers which may have consequences for pollinators and the resources they...
This thesis will explore the architectural material culture excavated at the Robert Newell Homestead (35MA41), currently located in Champoeg, Oregon. Specifically, the research focuses on the vernacular architecture or the features and construction methods used that both reflect the environment and the cultural traditions of the dwellings occupants. The Robert...
Relatively little is known about how various factors influence snow water storage in forested mountain landscapes in maritime (warm winter) climates. This study took advantage of multiple snow data sources including long-term data, synoptic sampling, remote sensing, and modeling to examine factors influencing snow dynamics in the H.J. Andrews Experimental...
The purpose of this research was to see if there were technological differences in ground stone manufacturing and use from a single site that had been occupied for over 600 years, A.D. 550-A.D. 1150, and had multiple occupations that evolved over time (Late Pithouse Phases, Georgetown, San Francisco, and Three...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
A variety of studies were conducted by some 13 states and agencies to

Before we can write intelligently concerning
any subject, we must understand exactly what we are
writing about. As the title tells us, this thesis
deals exclusively with the work and incidentally with
the lives of Robert and Elizabeth Barrett Browning, two
notable nineteenth century poets.
This thesis is based on the excavations of the Robert Newell farmstead (35MA41), excavated in 2002 and 2003 by the Oregon State University Department of Anthropology archaeological field school. Robert Newell lived at this farm from 1843- 1854. Major architectural features, including a brick hearth and postholes were discovered at...
