Geochemical Evidence for Slab Melting in the Trans-Mexican Volcanic Belt
(Oxford University Press, 2007)Geochemical studies of Plio-Quaternary volcanic rocks from the Valle de Bravo-Zitacuaro volcanic field (VBZ) in central Mexico indicate that slab melting plays a key role in the petrogenesis of the Trans-Mexican Volcanic ... -
Geochemical evidence for widespread euxinia in the Later Cambrian ocean
(Nature Publishing Group, 2011)Widespread anoxia in the ocean is frequently invoked as a primary driver of mass extinction as well as a long-term inhibitor of evolutionary radiation on early Earth. In recent biogeochemical studies it has been hypothesized ... -
Geochemical Modeling of Evaporation Processes on Mars: Insight from the Sedimentary Record at Meridiani Planum
(Elsevier, 2005)New data returned from the Mars Exploration Rover (MER) mission have revealed abundant evaporites in the sedimentary record at Meridiani Planum. A working hypothesis for Meridiani evaporite formation involves the evaporation ... -
Geodesic Currents on Hyperbolic Surfaces: Entropy, Intersection Number, and Equidistribution
(2023-05-16)Let $X$ be a hyperbolic surface of finite volume. In this thesis, we investigate the behavior of closed geodesics on $X$ and their geometric intersections. Specifically, we address the following three questions: 1. How ... -
Geodesic planes in hyperbolic 3-manifolds
(2021-05-03)Let P be a geodesic plane in a convex cocompact, acylindrical hyperbolic 3-manifold M. Assume that P^*=M^*\cap P is nonempty, where M^* is the interior of the convex core of M. Does this condition imply that P is either ... -
Geodetic Constraints on San Francisco Bay Area Fault Slip Rates and Potential Seismogenic Asperities on the Partially Creeping Hayward Fault
(Wiley-Blackwell, 2012)The Hayward fault in the San Francisco Bay Area (SFBA) is sometimes considered unusual among continental faults for exhibiting significant aseismic creep during the interseismic phase of the seismic cycle while also ... -
Geodetic Imaging of Coseismic Slip and Postseismic Afterslip: Sparsity Promoting Methods Applied to the Great Tohoku Earthquake
(Wiley-Blackwell, 2012)Geodetic observations of surface displacements during and following earthquakes such as the March 11, 2011 great Tohoku earthquake can be used to constrain the spatial extent of coseismic slip and postseismic afterslip, ... -
Geodetic Imaging of Fault System Activity
(2014-06-06)Geodetic observations provide kinematic constraints on the behavior of tectonically active fault systems. Estimates of earthquake cycle activity derived from these constraints may depend on modeling assumptions and/or ... -
Geodetic Imaging of Plate Motions, Slip Rates, and Partitioning of Deformation in Japan
(American Geophysical Union, 2010)Interseismic deformation in Japan results from the combined effects of tectonic processes including rotation of crustal blocks and the earthquake cycle process of elastic strain accumulation about upper plate faults and ... -
Geodetically constrained models of viscoelastic stress transfer and earthquake triggering along the North Anatolian fault
(Wiley-Blackwell, 2016)Over the past 80 years, 8 MW > 6.7 strike-slip earthquakes west of 40° longitude have ruptured the North Anatolian fault (NAF) from east to west. The series began with the 1939 Erzincan earthquake in eastern Turkey, and ... -
Geodynamic Insights on Critical Climate Events in Earth History
(2021-05-06)This interdisciplinary thesis aims to elucidate processes responsible for sea-level changes during climate events spanning the Miocene to present day, using the tools of numerical geodynamics and theoretical geophysics. ... -
The Geoengineered Planet

Geoengineering: The world's largest control problem
(IEEE, 2014)Solar geoengineering (or Solar Radiation Management, SRM) refers to any intentional, large-scale manipulation of the Earth's incoming solar radiation to offset some of the effects of anthropogenic greenhouse gases, reducing ... -
Geographic Constraints on Social Network Groups
(Public Library of Science (PLoS), 2011)Social groups are fundamental building blocks of human societies. While our social interactions have always been constrained by geography, it has been impossible, due to practical difficulties, to evaluate the nature of ... -
Geographic differences in effects of experimental warming on ant species diversity and community composition
(Ecological Society of America, 2014) -
Geographic distribution of the anti-parasite trait “slave rebellion”
(Springer Nature, 2012)Social parasites exploit the brood care behavior of other species and can exert strong selection pressures on their hosts. As a consequence, hosts have developed defenses to circumvent or to lower the costs of parasitism. ... -
Geographic Propensity Scores for Endogenous Boundaries: An Application to HOLC Redlining
(2022-06-03)Geographic policies often come in two parts: first, geographic boundaries are determined, and second, a treatment is applied based on the boundaries. Separating the effect of the treatment from the boundary drawing process ... -
Geographic Truths: Local Communities and Politics in the 21st Century
(2023-05-08)Are local communities still relevant to politics? Though economic globalization has made national boundaries more porous, the geographic concentration of the populist vote suggests that local factors retain political ... -
Geographic Variation in Network Structure of a Nearctic Aquatic Food Web
(Blackwell Publishing Ltd, 2011)Aim: The network structure of food webs plays an important role in the maintenance of diversity and ecosystem functioning in ecological communities. Previous research has found that ecosystem size, resource availability, ...
