Insights into the Geochemical Evolution of the Youngest Toba Tuff (Sumatra, Indonesia) Magma Chamber Through the Lens of Zircon-hosted Melt Inclusions

Creator:: Lerner, Allan
Abstract:: Supervolcanic eruptions are among the most catastrophic phenomena on Earth, erupting 100s-1000s of cubic kilometers of magma, and producing devastating local effects and global climate perturbations. The largest supervolcanic eruption of the last 28 Ma was the 74 ka Youngest Toba Tuff (YTT) eruption from Sumatra, Indonesia, which erupted 2,800...

Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:: Menking, James A.
Abstract:: New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

Up-estuary extent and lithologic characteristics of tsunami deposits attributed to the 1700 Cascadia earthquake within Alsea Bay, OR

Creator:: Spruell, John T.
Abstract:: Cascadia’s 1700 earthquake generated a tsunami and widespread subsidence along Pacific Northwest coastline. The tsunami deposited sandy sediments in many Oregon coastal estuaries, such as Alsea Bay. Although the recurrence of subduction-generated megathrust earthquakes and tsunami events in this region are recorded in the stratigraphy, knowledge of the full inland...

Climate change in the Northwest : implications for our landscapes, waters, and communities

Creator:: Dalton, Meghan M., Mote, Philip W., Snover, Amy K., and Oregon Climate Change Research Institute
Abstract:: Climate Change in the Northwest: Implications for Our Landscapes, Waters, and Communities is a report aimed at assessing the state of knowledge about key climate impacts and consequences to various sectors and communities in the Northwest United States. This report draws on two recent state climate assessments in Washington in...

Fourth Oregon climate assessment report. State of climate science : 2019

Creator:: Mote, Philip W., Abatzoglou, John, Dello, Kathie D., Hegewisch, Katherine, Rupp, David E., and Oregon Climate Change Research Institute
Abstract:: This report, required by state law under HB3543, provides a comprehensive assessment of the state of science of climate change as it pertains to Oregon, covering the physical, biological, and social dimensions. The first chapter summarizes the current state of knowledge of physical changes in climate and hydrology, focusing on...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Biophysical feedback mediates effects of invasive grasses on coastal dune shape

Creator:: Zarnetske, Phoebe L., Hacker, Sally D., Seabloom, Eric W., Ruggiero, Peter, Killian, Jason R., Maddux, Timothy B., and Cox, Daniel
Abstract:: Vegetation at the aquatic–terrestrial interface can alter landscape features through its growth and interactions with sediment and fluids. Even similar species may impart different effects due to variation in their interactions and feedbacks with the environment. Consequently, replacement of one engineering species by another can cause significant change in the...

Local and Regional Patterns in Eelgrass (Zostera marina L.) Communities Along an Upwelling-Productivity Gradient in Oregon Estuaries, USA

Creator:: Motley, Jennifer
Abstract:: In this thesis, I investigate the organization of eelgrass (Zostera marina L.) and mesograzer communities across local and regional scales in three upwelling- influenced estuaries located along the Oregon coast, USA. Eelgrass ecosystems are an important source of primary production in estuarine systems, providing numerous ecosystem services, including nursery habitat...

Kinematics and Dynamics of a Model Eastern-boundary Poleward Undercurrent

Creator:: Duran, Rodrigo
Abstract:: A carefully calibrated primitive-equation model from 41°N to 48°N is used to study the poleward undercurrent off the US west coast. Chapter 2 describes poleward flow over the slope from Eulerian and Lagrangian perspectives. The model is robust, in the sense of several characteristics being qualitatively consistent with observational and...

Ocean Acidification Impacts on Bivalves at Multiple Organizational Levels: From Individual Larvae to Bivalve Aggregations Habitats

Creator:: Gimenez Calvo, Iria
Abstract:: Many marine bivalves are sensitive to ocean acidification (OA) stress and often show heightened sensitivity during brief early larval and post-larval life stages, potentially leading to population bottlenecks. Most of the evidence to date has been collected in laboratory experiments that focused on physiological responses at the organismal level under...
