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 ... -
Meridional Heat and Salinity Transports and the Surface Freshwater Exchange Derived from the OSNAP (Overturning in the Subpolar North Atlantic Program) Array between August 2014 and May 2018
(Georgia Institute of Technology, 2021-01)An international effort, Overturning in the Subpolar North Atlantic Program (OSNAP), is a partnership among oceanographers from the US, UK, Germany, the Netherlands, Canada and China whose goal is to measure and understand ... -
A Proposed Improvement for Measuring Hydroxylamine in Seawater
Hydroxylamine is a chemical intermediate in the nitrogen cycle that can quickly react via biotic and abiotic processes to yield nitrous oxide, a potent greenhouse gas. Because of its high reactivity, hydroxylamine tends ... -
Microcat, Aquadopp, and ADCP data from the 2016-2018 Labrador Sea eastern boundary mooring array as part of OSNAP (Overturning in the Subpolar North Atlantic Program)
(Georgia Institute of Technology, 2020-10-15)The Overturning of the Subpolar North Atlantic Program (OSNAP) is an effort to determine the strength of the meridional overturning circulation and associated heat and freshwater fluxes in the subpolar North Atlantic. ... -
Meridional Overturning Circulation Observed by the OSNAP (Overturning in the Subpolar North Atlantic Program) Array from August 2014 to May 2018

Improved understanding of earthquake interaction with waveform matching method
(Georgia Institute of Technology, 2020-08-03)As one of the most common geological phenomena, earthquake occurs in various tectonic settings, such as fault zone along plate boundaries, volcanoes, and oil/gas production sites. The stress changes caused by large earthquake ... -
Understanding the role of formic acid in fine and coarse particle mode
(Georgia Institute of Technology, 2020-07-21)Formic acid partitioning was investigated at two sites in the southeast U.S., Yorkville, GA and Jefferson Street (JST). Previous studies in the southeast have shown that observed formic acid partitioning to fine particles ... -
Prominent contribution of hydrogen peroxide to intracellular reactive oxygen species (ROS) generated upon exposure to naphthalene secondary organic aerosols (SOA)
