Simulating extreme total water levels using a time-dependent, extreme value approach

Creator:: Serafin, Katherine A. and Ruggiero, Peter
Abstract:: Coastal flood hazard zones and the design of coastal defenses are often devised using the maximum recorded water level or a ‘‘design’’ event such as the 100 year return level, usually projected from observed extremes. Despite technological advances driving more consistent instrumental records of waves and water levels, the observational...

What's streamflow got to do with it? A probabilistic simulation of the competing oceanographic and fluvial processes driving extreme along-river water levels

Creator:: Serafin, Katherine A., Ruggiero, Peter, and Parker, Kai
Abstract:: Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...

Emulation as an approach for rapid estuarine modeling

Creator:: Parker, Kai, Ruggiero, Peter, Serafin, Katherine A., and Hill, David F.
Abstract:: Probabilistic flood hazard assessment is a promising methodology for estuarine risk assessment but currently remains limited by prohibitively long simulation times. This study addresses this problem through the development of an emulator, or surrogate model, which replaces the simulator (in this case the coupled ADCIRC+SWAN model) with a statistical representation...

Evaluating relocation extent versus covariate resolution in habitat selection models across spatiotemporal scales

Creator:: Nelson, Peter R., Joly, Kyle, Roland, Carl A., and McCune, Bruce
Abstract:: Many habitat selection studies have focused on the importance of spatiotemporal scales and sample size, yet often hidden within is a trade-off between using more animal locations versus more predictive covariates. Few have evaluated the outcome of choosing between these two different paths even though the trade-off can have significant...

Sediment Transport Study: Phase Two: Baseline Observations and Characterization of Sediment Transport Processes for the Reedsport Wave Energy Site

Creator:: Ruggiero, Peter, Holman, Robert A., and Allen, Jonathan C.
Abstract:: This project was carried out collaboratively by Oregon State University (OSU) and the Oregon Department of Geology and Mineral Industries (DOGAMI) and involved continuation of the beach monitoring program begun in summer 2009 to determine baseline conditions and beach variability at the site of the planned Reedsport wave energy conversion...

Microbes, macrofauna, and methane: A novel seep community fueled by aerobic methanotrophy

Creator:: Thurber, Andrew R., Levin, Lisa A., Rowden, Ashley A., Sommer, Stefan, Linke, Peter, and Kroeger, Kerstin
Abstract:: During the discovery and description of seven New Zealand methane seep sites, an infaunal assemblage dominated by ampharetid polychaetes was found in association with high seabed methane emission. This ampharetid-bed assemblage had a mean density of 57,000 ± 7800 macrofaunal individuals m⁻² and a maximum wet biomass of 274 g...

Detection and Attribution of Observed Changes in Northern Hemisphere Spring Snow Cover

Creator:: Rupp, David E., Mote, Philip W., Bindoff, Nathaniel L., Stott, Peter A., and Robinson, David A.
Abstract:: Abstract: Significant declines in spring Northern Hemisphere (NH) snow cover extent (SCE) have been observed over the last five decades. As one step toward understanding the causes of this decline, an optimal fingerprinting technique is used to look for consistency in the temporal pattern of spring NH SCE between observations...

Tree-ring analysis of the fungal disease Swiss needle cast in western Oregon coastal forests

Creator:: Lee, E. Henry, Beedlow, Peter A., Waschmann, Ronald S., Burdick, Connie A., and Shaw, David C.
Abstract:: Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of climate change and forest management practices in the increase is unclear. We analyzed tree-ring chronologies from six late-successional...

Macrophyte wrack on sandy beaches of the US Pacific Northwest is linked to proximity of source habitat, ocean upwelling, and beach morphology

Creator:: Reimer, Jessica N., Hacker, Sally D., Menge, Bruce A., and Ruggiero, Peter
Abstract:: Marine macrophyte wrack (macroalgae and seagrasses) frequently washes onto beaches but little is known about the factors controlling its biogeographic variability. We report on a large-scale study of macrophyte wrack deposition patterns on the US Pacific Northwest coast. We measured macrophyte wrack on 12 sandy beach sites from southern Washington...

Weak Stock Bycatch Avoidance in the West Coast Ocean Salmon Fishery: A Bioeconomic Model Using Spatio-Temporal Data from Commercial Fishermen

Creator:: Otto, Saskia A., Simons, Sarah, Stoll, Josua, Lawson, Peter, and Lewis, Staci
Abstract:: The spatio-temporal overlap of morphologically undistinguishable weak and healthy stocks is a major concern for the Pacific Northwest troll Chinook salmon fishery. Regular fishery closures have led to major financial losses calling for alternative regulatory measures. One approach for such complex and pressing socio-ecological challenges is the transition towards transdisciplinary...
