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 ... -
Earth's oxygen and phosphorus cycle and the evolution of animal life
The purpose of this study is to reconstruct an environmental context for the emergence and expansion of early animal life during the Middle Proterozoic (∼1.8–0.8 billion years ago). Specifically, we examined the spatially ... -
The impacts of atmospheric radiation on studies of planetary habitability
(Georgia Institute of Technology, 2018-07-26)The conditions required for Earth-like life to emerge on a planet are thought to include the presence of liquid water, the availability of energy, the existence of organic material, and shielding from high energy charged ... -
A coral ensemble record of the El Niño southern oscillation over the mid-to-late holocene
(Georgia Institute of Technology, 2017-07-28)The El Niño-Southern Oscillation (ENSO) represents the largest source of year-to-year global climate extremes. However, its sensitivity to external climate forcing, whether natural or anthropogenic, is difficult to assess ... -
Fault zone imaging and earthquake detection with dense seismic arrays
(Georgia Institute of Technology, 2017-07-13)Natural earthquakes occur on faults. The relationship between fault zone structures and earthquake behaviors remains one of the most interesting problems in seismology. As an important tool to detect earthquakes and image ... -
The preservation, distribution, and detectability of lipid biomarkers in the Atacama desert and implications for Mars
(Georgia Institute of Technology, 2017-07-13)Desert environments on Earth are colonized by organisms adapted to desiccation. We hypothesized that extreme and prolonged dryness might impart too great a challenge for microbial survival. To test this, we surveyed ... -
Landslides on Ceres
(Georgia Institute of Technology, 2018-04-30)I analyze landslides on Ceres using several quantitative approaches to constrain the composition and structure of the top few kilometers of Ceres’ crust. I focus on a subset of archetypal landslides classified morphologically ... -
