Deepest sample in the North Pacific

The paper ‘A Novel Molecular Approach for Tracing Terrigenous Dissolved Organic Matter into the Deep Ocean’ led by Medeiros lab and recently published in GBC (volume 30, 689-699) is now featured on its website. The study identifies 184 molecular formulae that are indicators of riverine inputs (referred to as t-Peaks) and tracks their distribution in the deep North Atlantic and North Pacific Oceans (check it here). Congrats to the authors!

The Fantastic Four!

The fantastic four!

On May 13, four of our fantastic students received their graduate degrees during the 2016 Graduate Commencement Ceremony. The PhD degree was awarded to Qian Liu (advisor Tim Hollibaugh), to Chen Shen (advisor Brian Hopkinson), to Yuntao Wang (advisor Renato Castelao), and the MS degree was awarded to Lydia (Meg) Babcock-Adams (advisor Patricia Medeiros). Chen, Yuntao, and Meg were the first students graduated in Hopkinson’s, Castelao’s and Medeiros’ lab, respectively. It was a day to celebrate! We wish all the best to the ‘fantastic four’!

Dr. Adrian Burd part of team picked by NASA, Air Force to build and launch two cube satellites

Dr. Adrian Burd is part of an interdisciplinary team tapped by NASA and the Air Force to build and launch two cutting edge small satellites, part of the first space program at UGA. While the Small Satellite Research Lab has pledged financial support from multiple entitities within UGA, a crowdfunding project has also been launched.

Chen Shen successfully defends doctoral dissertation

Chen Shen, a student in Brian Hopkinson’s lab, successfully defended her thesis “Carbon Dioxide Concentrating Mechanisms in Marine Diatoms: Genetics, Physiology, and Diversity” on April 20, 2016.  Chen’s work shed light on the molecular mechanisms that are used by marine diatoms, an important group of algae in the ocean, to acquire carbon for photosynthesis. These systems are known as carbon dioxide concentrating mechanisms and they are currently of interest for the way in which they modify the response of marine algae to rising CO2 concentrations.

Scientists discover new reef system at mouth of Amazon River

Athens, Ga. – A new reef system has been found at the mouth of the Amazon River, the largest river by discharge of water in the world. As large rivers empty into the world’s oceans in areas known as plumes, they typically create gaps in the reef distribution along the tropical shelves—something that makes finding a reef in the Amazon plume an unexpected discovery.

An international team—including scientists from the University of Georgia and the Federal University of Rio de Janeiro—documented their findings in an April 22 study published in the journal Science Advances.
