A genomic view of Flavobacteria and their role in the bacterioplankton of the oceans


Nitrogen Cycling in Eutrophic systems


Submarine groundwater discharge (SGD)

Submarine groundwater discharge (SGD) is a process defined as any and all input of water into a surface water body through the sediment - water interface, independent of the driving force, and the fluid source and composition. Historically, the report of the existence of SGD dates back many centuries, when a submarine spring 2.5 miles offshore from Latakia, Syria, in the Mediterranean Sea was described. Other historical records focus on the…


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…


Amazon Shelf Sedimentary Environments

The purpose of this seminar is to begin with a general overview of the shelf and end with the carbonate reefs.  


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…

Estimating diapycnal mixing in the ocean: How close are we?

Mixing by turbulent motions in the ocean is important for global ocean circulation, nutrient supply to surface waters, and the global ocean heat budget. Turbulent mixing takes the form of a diffusive process where the vertical flux is proportional to the concentration gradient with an eddy diffusivity coefficient, Kz, as a constant of proportionality. Osborn (1980) suggested that Kz is in turn related to the flux Richardson number (Rif) or…

Compositional variations in dissolved organic matter and black carbon across hydrologic and aquatic gradients

Dissolved organic matter (DOM) is viewed as an information-rich set of molecular tracers which carry the chemical signature of its source and subsequent journey to its point of analysis. The overarching goal of my research is to read the molecular signatures of DOM using advanced analytical techniques to reveal its source, reactivity, and environmental fate. Upstream landscapes and rainfall-runoff processes have emerged as major controllers of…
