Research on marine systems includes physical, chemical and biological and geological oceanography and investigation of coastal-zone processes and systems, as well as chemical and biological ecology of marine environments. In addition to research capabilities located on the Georgia Tech campus, faculty and students have the opportunity to conduct research programs at the Skidaway Institute of Oceanography in Savannah, GA, and is a unit of the University System of Georgia. Existing programs include physical and biological modeling, sensor development, field studies, remote sensing and paleoceanography. Research is conducted in both the coastal zone and open ocean, and current regional studies include the California coastal ocean, Indian Ocean, tropical Pacific Ocean, Gulf of Alaska, Labrador Sea, Gulf of Mexico, South China Sea and the Arctic Ocean.
Paleoclimate research at Georgia Tech seeks to understand how and why climate has changed in the past. Looking back beyond the instrumental record can provide us with the context to better understand present-day climate change. Our work focuses on reconstructing past temperature, precipitation, and circulation patterns of key components of the global climate system such as the tropical Pacific El Nino-Southern Oscillation and the North Atlantic thermohaline circulation. We apply a wide variety of geochemical paleoclimate proxies to carbonate archives such as corals, deep-sea sediments, and cave stalagmites to reconstruct climate. We are actively involved in proxy calibration research, which takes us into the field on cruises and other expeditions, as well as paleoclimate modeling, which involves collaboration with other EAS faculty in the ocean/climate group. Our analytical facilities include a ThermoFisher Delta Plus/Kiel and a ThermoFisher 235/Kiel (for the measurement of oxygen isotopes in carbonates), a JY-Horiba ICP-OES (for the measurement of trace metals in solids and waters), and a Picarro water oxygen isotope analyzer.
