Dynamics of ammonia oxidizing Archaea in the South Atlantic Bight

ABSTRACT:  Previous work on the Georgia, USA coast revealed consistent mid-summer peaks in the abundance of Thaumarchaeota accompanied by spikes in nitrite concentration.  We collected data on the distribution of Thaumarchaeota, ammonia-oxidizing Betaproteobacteria (AOB), nitrite-oxidizing Nitrospina, environmental variables and rates of ammonia oxidation during 6 cruises in the South Atlantic Bight from April to November 2014 to evaluate the areal extent and timing of the bloom.  The abundance of Thaumarchaeota marker genes (16S rRNA and amoA) increased at inshore and nearshore stations st

Georgia Sea Grant 2017 Research Symposium

Please join us for the 2017 Research Symposium on June 1-2 at the Graduate Hotel in Athens, Ga. The symposium will highlight Georgia Sea Grant’s research program, where Sea Grant-funded scientists from across the state will share their research findings. A reception will follow.

On day two, prospective researchers are invited to a workshop where we will provide an overview of our FY2018-2020 call of proposals and give tips and advice about preparing a strong application. Registration is required.

Please email Angela Llewllayn at angelal@uga.edu by May 25 to RSVP.

Developing Acoustic Instruments for Measuring Flow velocity and Sediment Concentration in Rivers and Coastal Waters

About the presentation: "The presentation is organized as follows. At first, the experimental works I carried out during my PhD studies to explore tide-driven influential parameters on sediment transport in Ota Diversion Channel, Hiroshima, Japan, are briefly described. This part mainly discusses the application of conventional acoustic systems, their abilities, and challenges that inspired me to start working on Shallow Acoustic Tomography technique.
