• Magnetoplasma Interactions with Icy Bodies 

  Hale, John Phillip Marshall (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 

  Lu, Yi (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 

  Liu, Xinyi

  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 

  McDonald, George D. (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 

  Grothe, Pamela R. (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 

  Li, Zefeng (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 

  Wilhelm, Mary Beth (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 

  Chilton, Heather (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 ...

• Reanalysis of ammonia/ammonium partitioning and particle pH prediction from the Atlanta Aerosol Nucleation and Real-Time Characterization Experiment (ANARChE) 

  Wang, Qi (Georgia Institute of Technology, 2018-04-27)
