The impact of climate change on California’s ecosystem services

Creator:: Shaw, M. Rebecca, Pendleton, Linwood, Cameron, D. Richard, Morris, Belinda, Bachelet, Dominique, Klausmeyer, Kirk, MacKenzie, Jason, Conklin, David R., Bratman, Gregrory N., Lenihan, James, Haunreiter, Erik, Daly, Christopher, and Roehrdanz, Patrick R.
Abstract:: Ecosystem services play a crucial role in sustaining human well-being and economic viability. People benefit substantially from the delivery of ecosystem services, for which substitutes usually are costly or unavailable. Climate change will substantially alter or eliminate certain ecosystem services in the future. To better understand the consequences of climate...

Simulating vegetation shifts and carbon cycling in Yosemite National Park

Creator:: Conklin, David R.
Abstract:: The vegetation in Yosemite National Park changed during the 20th century and may change in the 21st century in response to climate change. Vegetation surveys made during the 1930s and the 1990s provide benchmark records separated by 60 years. This study uses the MC1 dynamic global vegetation model to forecast...

A Tale of Two Spills: Novel Science and Policy Implications of an Emerging New Oil Spill Model

Creator:: Peterson, Charles H., Anderson, Sean S., Cherr, Gary N., Ambrose, Richard F., Anghera, Shelly, Bay, Steven, Blum, Michael, Condon, Robert, Dean, Thomas A., Graham, Monty, Guzy, Michael, Hampton, Stephanie, Joye, Samantha, Lambrinos, John, Mate, Bruce, Meffert, Douglas, Powers, Sean P., Somasundaran, Ponisseril, Spies, Robert B., Taylor, Caz M., Tjeerdema, Ronald, and Adams, E. Eric
Abstract:: The 2010 Deepwater Horizon oil release posed the challenges of two types of spill: a familiar spill characterized by buoyant oil, fouling and killing organisms at the sea surface and eventually grounding on and damaging sensitive shoreline habitats, and a novel deepwater spill involving many unknowns. The subsurface retention of...

Economic feasibility and environmental life cycle assessment of ethanol production from lignocellulosic feedstock in Pacific Northwest U.S.

Creator:: Juneja, Ankita, Kumar, Deepak, and Murthy, Ganti S.
Abstract:: Bioethanol produced from the lignocellulosic feedstock is a potential alternative to fossil fuels in transportation sector and can help in reducing environmental burdens. Straw produced from perennial ryegrass (PR) and wheat is a non-food, cellulosic biomass resource available in abundance in the Pacific Northwest U.S. The aim of this study...

Measurement Tool for Dynamics of Soil Cracks

Creator:: Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., and Selker, John S.
Abstract:: Shrinkage cracks in soil function as a dominant control on the partitioning and distribution of moisture fluxes in the vadose zone. Their dynamics influence moisture balance and control water availability for runoff, deep infiltration, and near-surface storage. We present a new low-cost field instrument to monitor the temporal change in...

Modeling surface water and groundwater interactions near Milton-Freewater, Oregon

Creator:: Petrides Jimenez, Aristides Crisostomos
Abstract:: The gravel aquifer of the Oregon side of Walla Walla River Basin has a strong hydrologic connection to surface water through a series of springs, unlined irrigation canals, the Walla Walla River, numerous wells and, since 2004, artificial recharge to the shallow aquifer using infiltration basins. The finite element Integrated...

Downstream processing of microalgal biomass for biofuels

Creator:: Sander, Kyle B.
Abstract:: This thesis documents the work carried out investigating the downstream processing of algal biomass for biofuel production. A life cycle assessment was conducted on a hypothetical algal biodiesel process in which it was found drum drying and cell component separation were life cycle intensive processes. A laboratory experiment was conducted...

Development of a Statistical Emulator of US Crop Yields via a Deep Neural Network Approach

Creator:: Proctor, Kyle W.
Abstract:: Agricultural systems are inherently complex; understanding these systems requires knowledge of climatology, plant physiology, soil physics, economics, and the human psychology of the farmers themselves. Decision support tools strive to leverage existing data to help guide stakeholders towards the best policies and practices for their situation. Quantitative crop simulation models...

Evapotranspiration: a process driving mass transport and energy exchange in the soil-plant-atmosphere-climate system

Creator:: Katul, Gabriel G., Oren, Ram, Manzoni, Stefano, Higgins, Chad, and Parlange, Marc B.
Abstract:: The role of evapotranspiration (ET) in the global, continental, regional, and local water cycles is reviewed. Elevated atmospheric CO₂, air temperature, vapor pressure deficit (D), turbulent transport, radiative transfer, and reduced soil moisture all impact biotic and abiotic processes controlling ET that must be extrapolated to large scales. Suggesting a...

Life cycle assessment of energy and GHG emissions during ethanol production from grass straws using various pretreatment processes

Creator:: Kumar, Deepak and Murthy, Ganti S.
Abstract:: Background, aim and scope: The aim of this study was to perform a well-to-pump life cycle assessment (LCA) to investigate the overall net energy balance and environmental impact of bioethanol production using Tall Fescue grass straw as feedstock. The energy requirements and green house gas (GHG) emissions were compared to...
