A comprehensive study of Titan's magnetic pile-up region during the Cassini era
(Georgia Institute of Technology, 2020-04-28)While Saturn's largest moon Titan is devoid of an intrinsic magnetic field, draping of the giant planet's magnetospheric field around Titan's ionosphere generates a pile-up region at the moon's ramside. In this study, we ... -
SEISMIC IMAGING WITH EXTENDED IMAGE VOLUMES AND SOURCE ESTIMATION
(Georgia Institute of Technology, 2020-04-25)Seismic imaging is an important tool for the exploration and production of oil & gas, carbon sequestration, and the mitigation of geohazards. Through the process of seismic migration, images of subsurface geological ... -
Interactions between reactive nitrogen and manganese: Implications for marine nitrous oxide cycling
(Georgia Institute of Technology, 2020-04-25)Nitrous oxide (N2O) is a potent greenhouse gas that can destroy stratospheric ozone. Production and consumption of N2O has long been assumed to be controlled solely by nitrogen-metabolizing microbes. It has recently been ... -
ANTHROPOGENIC AND NATURAL NITROGEN OXIDES EMISSIONS OVER THE UNITED STATES: COMPREHENSIVE EVALUATIONS AND IMPLICATIONS FOR SURFACE OZONE PREDICTION
(Georgia Institute of Technology, 2019-04-02)Nitrogen oxides (NOx = NO + NO2) play a crucial role in the formation of ozone and has significant impacts on the production of secondary organic and inorganic aerosols, thus affecting human health, global radiation budget, ... -
Signatures of the El Nino-southern oscillation on rainfall and cave dripwater oxygen isotopes in N. Borneo
(Georgia Institute of Technology, 2019-12-11)Oxygen isotope (δ18O) records of speleothem carbonates are a critical terrestrial paleoclimate archive, providing insight into past hydroclimate variations and past changes in atmospheric circulation. Specifically, time ... -
Understanding ocean iron dynamics and impacts on marine ecosystems
(Georgia Institute of Technology, 2019-11-12)Fe is one of the most important nutrients for phytoplankton growth in the ocean, making it a crucial element in the regulation of the ocean carbon balance and biogeochemical cycles. Atmospheric deposition of dissolved Fe ... -
DIURNAL AND SEASONAL VARIABILITY OF URANUS’ MAGNETOSPHERE UNDER DIFFERENT IMF
(Georgia Institute of Technology, 2018-11-13)The magnetosphere of Uranus is far from well known since there was only one fly-by measurement in history. In order to study the magnetosphere and its coupling mechanism with the solar wind, we used our multifluid ... -
APPLICATIONS OF SATELLITE RETRIEVALS IN DERIVING POLLUTANT EMISSIONS AND TRENDS
(Georgia Institute of Technology, 2017-11-03)This dissertation employs various satellite retrievals and the 3-D Regional chEmical trAnsport Model (REAM) to (1) identify and quantify the emission sources, and (2) derive pollutant trends. First, we use short-lived ... -
Remote triggering of microseismicity in Antarctica by large distant earthquakes
(Georgia Institute of Technology, 2019-07-30)Recent studies suggested that seismic waves from significant earthquakes could trigger shallow seismic events and deep tremor in tectonically active regions at the long-distance range. Dynamic stresses carried by teleseismic ... -
Multiphase reactive transport in planetary ices
(Georgia Institute of Technology, 2019-07-10)As an ice-ocean world itself, Earth provides a number of analog environments that can be used to better understand the dynamics of ice-ocean processes occurring on bodies like Europa [Eicken, 2002; Gleeson et al., 2012; ... -
Role of thiols in microbial metal reduction and Importance of organic-Fe(III) complexes on the benthic flux of iron from continental margin sediments
(Georgia Institute of Technology, 2018-08-24)Both Fe(III) and Mn(III,IV) oxides are ubiquitous in aquatic sediments and represent favorable terminal electron acceptors for microbial respiration. As a result, the dissimilatory reduction of Fe(III) and Mn(III,IV) ... -
Wildfires in earth system: Driver, transport and feedback
(Georgia Institute of Technology, 2018-08-08)Wildfires release large amounts of greenhouse gases, carbonaceous aerosols, and other pollutants, therefore having complex impacts on the earth climate, local weather, and air quality. To study the transport of the wildfire ... -
Understanding earthquake triggering and fault slip behavior based on improved earthquake catalogs
(Georgia Institute of Technology, 2018-07-27)Large earthquakes can alter the subsurface stress field on active faults across broad spatial and temporal windows, which would promote or inhibit slip on these faults. Besides dynamic ruptures during regular earthquakes, ... -
