Inorganic polyphosphate in the marine environment: field observations and new analytical techniques
(Georgia Institute of Technology, 2011-03-31)
Phosphorus (P) is a requirement for biological growth, but this vital nutrient is present at low or limiting concentrations across vast areas of the global surface ocean. Inorganic polyphosphate (poly-P), a linear polymer ...
Measuring present-day strain rates along the Fish Lake Valley fault system, Pacific-North America plate boundary
(Georgia Institute of Technology, 2012-05-07)
The eastern California shear zone (ECSZ) is located east of the San Andreas fault and contains a complex network of structures that accommodate ~25% of the relative displacement between the Pacific and North American plates. ...
Modulation of crustal magmatic systems by external tectonic forcing
(Georgia Institute of Technology, 2011-11-16)
We develop a two dimensional model that simulates the response of the crust to prolonged mantle-derived intrusions in arc environments. The domain includes the entire crustal section and upper mantle and focuses on the ...
Mainshock and early aftershock recording of the 2011/02/21 Mw6.3 earthquake in Christchurch, New Zealand
(Georgia Institute of Technology, 2011)
Below is the image and sound of the seismic recording at station HVSC (more than 1.5 g vertical acceleration) for the 2011/02/21 Mw6.3 New Zealand earthquake. This vertical seismogram is recorded by strong motion sensors ...
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 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 ...
Describing post-GOE oxygen availability with trace metal paleoredox proxies
(Georgia Institute of Technology, 2017-04-24)
Methods of describing local oxygen availability using coupled Mo isotopes and redox sensitive trace metal enrichments are applied to the Hotazel Iron Formation of the Transvaal Supergroup. These trace metal paleoredox ...
Cloud condensation nuclei spectra: measurement techniques and ambient sampling in the southeastern United States
(Georgia Institute of Technology, 2016-08-01)
Measurements of the ability of aerosols to act as cloud condensation nuclei (CCN) continue to be necessary to improve our understanding of the interaction between aerosols and clouds. Hardware improvements to the Droplet ...
Science for the Public Good? Federal Air Pollution and Climate Policy in the Current Political Era
(Georgia Institute of Technology, 2019-07-26)
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) ...
