Science for the Public Good? Federal Air Pollution and Climate Policy in the Current Political Era
(Georgia Institute of Technology, 2019-07-26)
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 ...
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 ...
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 ...
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, ...
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; ...
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 ...
Atlantic meridional overturning circulation variability since the last glaciation: Insights from a novel multiproxy approach
(Georgia Institute of Technology, 2019-11-11)
Atlantic Meridional Overturning Circulation (AMOC) transports warm surface water northward across the equator, carrying heat from the Southern to the Northern Hemisphere. AMOC plays a central role in the global redistribution ...
Dynamics, variability, and model representations of U.S. hydrological extremes
(Georgia Institute of Technology, 2019-11-07)
Hydrological extremes, including both extreme precipitation events and droughts, have profound impacts on human life, health, and socioeconomic well-being. U.S. hydrological extremes are dynamically connected to large-scale ...
Prominent contribution of hydrogen peroxide to intracellular reactive oxygen species (ROS) generated upon exposure to naphthalene secondary organic aerosols (SOA)
(Georgia Institute of Technology, 2019-07-26)
Multiple studies have found an association between exposure to particulate matter (PM) and adverse health endpoints. One of the suggested mechanisms in which inhalable particles exert damage is by inducing the overproduction ...
