Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:

Nomura, Keiko

Abstract:

Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...

Timing and Composition of Volcanism at Harrat Ithnayn, Western Saudi Arabia

Creator:

Alhejji, Suhail

Abstract:

Western Saudi Arabia hosts a number of young volcanic fields, known as “Harrats”. Harrats cover a significant proportion of western Saudi Arabia and are associated with significant volcanic hazards. However, the ultimate cause of volcanic activity remains unclear. Younger volcanism (<12 Ma) is clearly represented by the north-south-trending region known...

An Exploration of Climate Change, Conservation, and Cooperation, in Three Essays

Creator:

Johnson, Steven Mana'oakamai

Abstract:

The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:

Seabrook, Sarah

Abstract:

Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

Applying a Dynamic Time Warping Approach to Stratigraphic Correlation: Quaternary Magnetostratigraphy and Ediacaran–Cambrian Chemostratigraphy

Creator:

Hagen, Cedric J.

Abstract:

Magneto- and chemostratigraphic correlation underpins much of our understanding of Earth history, yet typical correlation techniques are neither quantitative nor objective. Within this dissertation, I detail my efforts to develop and apply dynamic programming-based algorithms that accomplish optimal and reproducible stratigraphic alignment. I apply these algorithms to three geologic intervals:...

The Deschutes Formation: evidence of extension-enhanced explosivity in the early High Cascades

Creator:

Pitcher, Bradley W.

Abstract:

The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...

Modeling Forest Response to Changing Climate Conditions in Western North America

Creator:

Hawkins, Linnia R.

Abstract:

Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...

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...

Chemical compositions of amphiboles found in veins and hosts rocks of Cretaceous plutons of the Northern Cascades

Creator:

George, Austin

Abstract:

The origin of hornblendite and other mafic mineral-rich veins found in Cretaceous plutonic rocks from the Northern Cascades is currently not well known. This study seeks to investigate the possible relationship between host plutonic rocks and hornblendite and pyroxene-rich veins by comparing the chemical compositions and petrographic features between the...

Mantle hotspot neon in basalts from the Northwest Lau Back-arc Basin

Creator:

Lupton, J. E., Arculus, R. J., Evans, L. J., and Graham, D. W.

Abstract:

The neon isotope compositions of basalts from the Northwest Lau Back-arc Basin reflect three-component mixing between an ocean island basalt (OIB) mantle hotspot component, mid-ocean ridge basalt (MORB) mantle, and atmosphere. Our study confirms that a mantle hotspot signature is present in the neon isotopes of both the Rochambeau Rifts...
