Hydrocarbon degradation under contrasting redox conditions in shallow coastal sediments of the northern Gulf of Mexico
(Georgia Institute of Technology, 2018-04-10)The objective of this dissertation research was to characterize sedimentary microbial populations that are active in degrading petroleum hydrocarbons that reach the seafloor during accidental oil spills. Whereas most ... -
Oceanographic controls of hydrocarbon degradation in the Gulf of Mexico
(Georgia Institute of Technology, 2018-04-05)The risk of an oil spill accident is increasing in pristine regions of the world’s oceans due to the development and transport of crude oil resources. The ability to predict the trajectory of spilled oil is critical for ... -
TROPOSPHERIC O3 MODELING STUDY: Contributions of anthropogenic and biogenic sources to O3-CO and O3-CH2O correlations
(Georgia Institute of Technology, 2018-04-06)Tropospheric O3 and CO are major pollutants in the troposphere. Strong correlation between O3 and CO was observed during the DISCOVER-AQ aircraft experiment in July 2011 over the Washington-Baltimore area. The observed ... -
Postseismic Response Following the 2012 Mw 7.6 Nicoya, Costa Rica Earthquake
(Georgia Institute of Technology, 2019-03-27)Characterization of the surface deformation related to the 2012 moment magnitude (Mw) 7.6 Nicoya earthquake was undertaken using continuous and campaign Global Positioning System (GPS) observations. This location is uniquely ... -
Estimating the tropospheric BrO budget from satellite measurements and improving retrievals of tropospheric BrO vertical column densities

Waveform analysis of repeating earthquakes - Implications for fault damage and healing processes
(Georgia Institute of Technology, 2009-08)The main goal of this project is to quantify the damage and healing processes in major fault zones that are recently ruptured in moderate to large earthquakes using waveform analysis of repeating earthquakes. -
Characterizing iron reducing microorganisms from anoxic ferruginous lake sediments
Lake Matano, Indonesia is a well-known ancient ocean analogue as its anoxic ecosystem in the subsurface sediments allow the growth of microorganisms capable of mediating anaerobic oxidation coupled to iron reduction. An ... -
Examining the spatiotemporal variability and direct impacts of mineral dust in Central Asia using a coupled regional modeling system and satellite-based sensors
(Georgia Institute of Technology, 2018-11-05)The airborne dust has been well recognized to have a significant impact on the climate system at varying spatial scales (through direct, indirect, and semi-direct effects), on biochemistry (providing marine phytoplankton ... -
The role of meridional modes in pacific climate variability and change
(Georgia Institute of Technology, 2018-11-13)Decadal changes in Pacific climate affect long-term transitions in marine ecosystems and influence the statistics of weather including ocean and atmosphere extremes such as strong droughts, hurricanes and marine heatwaves. ... -
Callisto: Signatures of plasma interaction, induction, and energetic particle dynamics at the Galilean moon
(Georgia Institute of Technology, 2018-10-23)Beneath the icy crust of Jupiter’s moon Callisto lies a putative liquid saltwater ocean. Properties of this ocean can be constrained through electromagnetic sounding: the 9.6° tilt between Jupiter's magnetic and rotational ... -
Exploiting subsurface ocean dynamics for decadal predictability in the upwelling systems of the Eastern North Pacific
(Georgia Institute of Technology, 2017-11-10)Given the strong recent interest in the decadal timescale variability and the potential for its predictability, it is critical to identify dynamics that carry inherent decadal-scale predictability. This work enhances our ... -
Interactions between climate variability and air pollution―A study of severe haze and large wildfires
(Georgia Institute of Technology, 2017-11-03)The drastically changing climate system plays a critical role in modulating emission and distribution conditions of air pollutants including greenhouse gases, aerosols, and tracer gases, while these air pollutants exert ... -
Improving the fidelity of coral-based climate records: A roadmap for bypassing intercolony variability and diagenesis
(Georgia Institute of Technology, 2017-08-25)The tropical oceans are a critical part of climate system, modulating global temperature and precipitation patterns on a variety of timescales. Yet, decadal-to-centennial scale climate variability in the tropics remains ... -
Magnetoplasma interactions with icy bodies
(Georgia Institute of Technology, 2017-08-25)Both the interaction between the Pluto-Charon system and the solar wind and Europa and the Jovian magnetosphere vary with system configuration. We use a global, three-dimensional, multifluid magnetohydrodynamic model (the ... -
Dynamical footprints of aerosols in extratropical atmospheric disturbances and circulation: A modeling analysis
(Georgia Institute of Technology, 2017-08-28)Synoptic-scale atmospheric disturbances occupy extratropics in wintertime and form extratropical “storm tracks”. These disturbances not only influence day-to-day weather variability but also modulate regional climates. The ... -
