Creator:: Thorstensson, Danil
Abstract:: This study tested the utility of a variable mixing efficiency formulation proposed by Mashayek, et al. (2017) for use in oceanographic models other than the modern, pre-industrial ocean. This formulation is used to calculate diapycnal (vertical) mixing due to unresolved subgrid-scale processes. Results from Last Glacial Maximum (LGM) simulations for...

Creator:: Juhl, Eli
Abstract:: Over the last 150 years, Oregon white oak habitat in the Willamette Valley has been converted to support grass crops, orchards and vineyards, cities, and conifer forests, nearly extirpating it from the Willamette Valley. Yet Oregon white oak offers many ecosystem services to the Willamette Valley and its residents. Recent...

Creator:: Vickery, Katrina
Abstract:: As climate change and its associated environmental and socioeconomic impacts become increasingly severe and imminent across the United States, it has become imperative for the public to be aware of and actively engaged with this issue. Although scientists generally perceive outreach in a positive light, a critical barrier that tends...
Resource Type:: Masters Thesis
Full Text:: collaborators and committee members, without whom, this project would not have been possible. To Dr. Andreas

Creator:: Edwards, Jon S.
Abstract:: Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...

Creator:: Niezgoda, Kyle
Abstract:: Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...
Resource Type:: Dissertation

Creator:: Fleishman, Erica and Oregon Climate Change Research Institute
Abstract:: Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...

Creator:: Stock, Marika P.
Abstract:: Nitrous oxide is an important greenhouse gas that has both natural and anthropogenic sources in the modern atmosphere (Ciais et al., 2013). This project expanded the knowledge of the history of atmospheric N2O in the geologic past by measuring N2O concentrations in air trapped in very old polar ice. A...
