Signatures in the Subsurface - Big & Small Data Approaches for the Spatio-Temporal Analysis of Geologic Properties & Uncertainty Reduction

Creator:: Rose, Kelly Kathleen
Abstract:: Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

Optimizing Reservoir Operations to Adapt to 21st Century Expectations of Climate and Social Change in the Willamette River Basin, Oregon

Creator:: Moore, Kathleen M.
Abstract:: Reservoir systems in the western US are managed to serve two main competing purposes: to reduce flooding during the winter and spring, and to provide water supply for multiple uses during the summer. Because the storage capacity of a reservoir cannot be used for both flood damage reduction and water...

Satellite-based detection and monitoring of phytoplankton blooms along the Oregon coast

Creator:: McKibben, S. M., Strutton, P. G., Foley, D. G., Peterson, T. D., and White, A. E.
Abstract:: We have applied a normalized difference algorithm to 8 day composite chlorophyll-a (CHL) and fluorescence line height (FLH) imagery obtained from the Moderate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft in order to detect and monitor phytoplankton blooms in the Oregon coastal region. The resulting bloom products, termed CHL[subscript rel]...

Seasonality of U[superscript K’]₃₇ temperature estimates as inferred from sediment trap data

Creator:: Rosell-Melé, Antoni and Prahl, Fredrick G.
Abstract:: The seasonality of sea surface temperatures (SST) estimated from the alkenone-U[superscript K’]₃₇ index has been a debated issue since the development of the sediment trap time series data from 34 sampling locations, we show that the maximum alkenone flux in sediment traps varies markedly across the oceans, only on latitude...

Spatio-Temporal Analysis and Modeling in the Marine Environment : Humpback Whale Genetic Variability and Seabird Distributions in the Northeastern Pacific Ocean

Creator:: Dick, Dorothy Marie
Abstract:: The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...

Sixth Oregon climate assessment

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...

Comparison of habitat restoration and enhancement methods for Olympia oysters (Ostrea lurida) in Yaquina Bay, Oregon

Creator:: Law, Karen H.
Abstract:: The Olympia oyster is a foundation species that increases habitat structure for associate species in estuarine systems of the Pacific Coast of North America (Kimbro & Grosholz, 2006). This oyster provides ecosystem services in the form of water filtration (zu Ermgassen et al., 2013), habitat for commercially valuable species such...

Assessing the Impact of Fishery Bait on Spatiotemporal Variation in the Feeding Ecology of Dungeness Crab (Cancer magister) Using Stable Isotopes, Gut Content Analysis & Fishermen Interviews

Creator:: Harbison, Toby N.
Abstract:: The commercial Dungeness crab (Cancer magister) fishery is Oregon’s largest trap-based fishery. Each year, crab vessels discard millions of pounds of bait, including squid, razor clams, and sardines, into the near-coastal ocean. Although the fishery season typically runs from December 1st through August 14th, most landings occur within the first...

Spatial and Temporal Landscape Responses to Progressive Tectonic Forcing along California Fault Systems

Creator:: Manopkawee, Pichawut
Abstract:: Understanding the degree to which topography of erosional landscapes in active mountain belts encode the rates and patterns of active deformation in the upper crust is a primary goal in the field of tectonic geomorphology. In particular, the convolved influence of variations in rock mass quality and the erodibility of...

Dynamic range and sensitivity requirements of satellite ocean color sensors: learning from the past

Creator:: Hu, Chuanmin, Feng, Lian, Lee, Zhongping, Davis, Curtiss O., Mannino, Antonio, McClain, Charles R., and Franz, Bryan A.
Abstract:: Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...
