Modelling the atmospheric chemistry of volcanic plumes
… way by which volatiles are transferred from the solid Earth to the atmosphere-hydrosphere system. Once released into the atmosphere, volcanic emissions rapidly undergo a complex series of chemical reactions. This thesis seeks to further the understanding of such processes by both observation and …

Model Uncertainties and Joint Inversion in Geophysics
Solid Earth geophysics is based on different types of data, such as magnetic, gravitational, electrical and seismic generally collected near or at the surface of the Earth, and is used to estimate physical parameters of the subsurface. The related parameter estimation problems are typically …

Resonance studies of artificial earth satellites
… a key process in obtaining information about the Earth and its environment. A study of the perturbations experienced by these satellites enables knowledge to be gained of the upper atmosphere, the gravity field, ocean tides, solid-Earth tides and solar radiation. The gravity field is expressed as …

Big Remote Sensing Data and Machine Learning for Assessing 21st Century Flooding and Socioeconomic Exposures
… rising sea levels due to climate change, solid earth changes, and other anthropogenic activities. With the increasing population in the era of changing climate, the number of people suffering from exposure to extreme events and sea level rise is expected to increase over the years. To …

Remote Sensing of 21st Century Water Stress for Hazard Monitoring in California
… mass loss also causes elastic deformation of the solid Earth, an opposite and smaller amplitude response than the poroelastic deformation of aquifer systems. These mass changes can disturb the regional stress field, which may influence earthquake activity. Both the elastic and poroelastic …

Insights from geodynamic models into ice flow, mantle magmatism, and their interactions
… geodynamic models to study processes within the Earth’s mantle and cryosphere. I begin by quantifying previously unconsidered sources of magmatic CO2. In Chapter 2, I predict how small concentrations of CO2 found in passively upwelling mantle throughout ocean basins may generate low-degree …

Forcings on Coccolithophore Evolution and Assemblage Changes
Marine microplankton play an integral role on Earth, not only in supporting entire ecosystems but also in affecting fundamental components of the climate system. However, our understanding of the factors driving microplankton evolution and assemblage changes is still incomplete. Here, I explore how …

Hydrothermal Transport in the Panama Basin and in Brothers Volcano using Heat Flow, Scientific Deep Sea Drilling and Mathematical Models
Two-thirds of submarine volcanism in the Earth's ocean basins is manifested along mid-ocean ridges and the remaining one-third is revealed along intraoceanic arcs and seamounts. Hydrothermal systems and the circulation patterns associated with these volcanic settings remove heat from the solid …

The Aptian evolution of the Galve sub-basin (Maestrat Basin; E Iberia)
… this thesis highlights the interplay between the solid Earth, oceans, atmosphere and life during this time interval, marked by higher CO2 atmospheric concentrations than nowadays and, consequently, by extreme climatic warmth and higher global sea levels. The most noteworthy aspect of this …

Ocean Tides Modeling using Satellite Altimetry
… sea ice, dissipate their energy in the ocean and solid Earth, and decelerate the Moon’s mean motion. Oceanographic studies and applications, including coastal or continental shelf ocean circulations, also require observations to be ‘de-tided’ using ocean tidal forward prediction models before …

The Mechanisms and Triggering of Earthquakes in the Ridge-Transform Environment
… the complicated structure and dynamics of our Earth. In the field of seismology, precise earthquake locations can illuminate regions of active seismic deformation, and help us better understand the orientation, mechanics, and kinematics of plate boundary zones. Although ocean bottom …

Time-lapse Acoustic Imaging of Oceanic Fronts and Eddies
… equipment which is used to image the solid Earth. In the water column, acoustic impedance contrasts are produced by variations in temperature and, to some extent, salinity. Acoustic impulses generated by an array of airguns suspended behind a vessel are reflected from these contrasts …

The evolution of the Greenland Ice Sheet from the Last Glacial Maximum to present-day: An assessment using glaciological and Glacial Isostatic Adjustment modelling
… around the margin, lateral variations in Earth structure and/or the pattern of ice margin retreat. Predictions of present-day vertical land motion generated using the new Huy2 model are highly sensitive to variations of upper mantle viscosity. Depending on the Earth model adopted, …

GPS Imaging of Vertical Land Motion and Earthquake Coseismic Displacements in the GPS Mega-Network
… field representative of coherent movement of the solid Earth. The research presented in this dissertation uses the GPS Imaging technique to identify and analyze a number of geophysical signals related to vertical land motion and earthquake deformation. Two studies examine vertical land motion …
