UGA Skidaway Institute scientists to study role of sunlight on marine CO2 production

Leanne Powers

Savannah, Ga. – Scientists at the University of Georgia Skidaway Institute of Oceanography have received a $527,050 grant from the National Science Foundation Chemical Oceanography Program to answer one of the long-standing questions about carbon in the ocean—the rate sunlight produces carbon dioxide from organic carbon molecules in the sea.

Jay Brandes, Leanne Powers and Aron Stubbins, all part of UGA’s Franklin College of Arts and Sciences department of marine sciences, will use a new technique they developed to measure this process, which is known as photo-degradation.

UGA Skidaway Institute scientists study dynamic Cape Hatteras waters

 

Savannah, Ga. – Sometimes called the “graveyard of the Atlantic” because of the large number of shipwrecks there, the waters off of Cape Hatteras on the North Carolina coast are some of the least understood on the U.S. eastern seaboard. University of Georgia Skidaway Institute of Oceanography scientist Dana Savidge is leading a team, which also includes UGA Skidaway Institute scientist Catherine Edwards, to investigate the dynamic forces that characterize those waters.

Climate change likely to increase black carbon input to the Arctic Ocean

Arctic rivers are the major way black carbon is transported to the ocean

Savannah, Ga. – University of Georgia Skidaway Institute of Oceanography scientist Aron Stubbins led a team of researchers to determine the levels of black carbon in Arctic rivers and found that the input of black carbon to the Arctic Ocean is likely to increase with global warming. The results of their study were recently published in the journal Frontiers in Earth Science.

Skidaway scientists work to predict 22nd century look of Georgia coast

UGA Skidaway Institute researcher LeeAnn DeLeo lowers the sensor to measure conductivity, temperature and depth from the surface to the bottom

University of Georgia Marine Sciences faculty, Clark Alexander is working on a project to predict how the Georgia coast—characterized by a complex system of barrier islands, salt marshes, estuaries, tidal creeks and rivers—may look 25, 50 and 100 years from now. As the sea level rises over the next century, that picture is changing. Read more here.
