Functions of global ocean microbiome key to understanding environmental changes

Athens, Ga. - The billions of marine microorganisms present in every liter of seawater represent a structured ecological community that regulates how the Earth functions in practically every way, from energy consumption to respiration. As inhabitants of the largest environment on Earth, microbial marine systems drive changes in every global system.

Congratulations Rachel Wang!

Shiyu Rachel Wang successfully defended her MS thesis on “Aquatic metabolism in a salt marsh dominated estuary - the O2 and CO2 journeys”. Her work combined measurements of inorganic carbon in tidal creeks with the quantification of water exchange and air-sea gas fluxes to establish a carbon budget in the Duplin River, Sapelo Island. Congratulations Rachel!

Oil dispersants can suppress natural oil-degrading microorganisms, new study shows

Athens, GA. – The use of chemical dispersants meant to stimulate microbial crude oil degradation can in some cases inhibit the microorganisms that naturally degrade hydrocarbons, according to a new study led by University of Georgia marine scientists. Their findings are based on laboratory-simulated conditions that mimic Gulf of Mexico deep waters immediately following the Deepwater Horizon oil spill. Read more here.

Congratulations Dr. Dornhoffer!

Thomas Dornhoffer successfully defended his PhD dissertation on Nov 5. The goal of his work was to investigate the impacts of benthic fauna across multiple scales, with particular emphasis on the importance of benthic fauna for solute fluxes across the sediment-water interface, and for nitrogen removal at the interface between the terrestrial and marine environments. Congratulations Dr. Dornhoffer!
