Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:

Truong, Thi B.

Abstract:

Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

Automated web-based analysis and visualization of spatiotemporal data

Creator:

Keon, Dylan B.

Abstract:

Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:

Kilbride, John B.

Abstract:

The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

AN ABSTRACT OF THE DISSERTATION OF John B. Kilbride for
Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:

Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy

Abstract:

Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:

Moore, Nicole E.

Abstract:

Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:

Konrad, Kevin

Abstract:

Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

The Geology and Geochemistry of the Haquira East Porphyry Copper Deposit of Southern Peru : Insights on the Timing, Temperature and Lifespan of the Magmatic-hydrothermal Alteration and Mineralization

Creator:

Cernuschi Rodilosso, Federico

Abstract:

This dissertation is informally divided into three major sections. In the first section (Chapter 2) I use data from field mapping, isotopic geochronology, whole rock geochemistry and trace element concentrations in zircons to examine the petrology, geochemistry and ages of the Haquira East porphyry copper deposit of southern Peru. In...

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:

Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.

Abstract:

Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...

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...

Quantifying Sensitivity and Adaptive Capacity of Shellfish in the Northern California Current Ecosystem to Increasing Prevalence of Ocean Acidification and Hypoxia

Creator:

Gossner, Hannah M.

Abstract:

The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...
