Archeologists find 16th-century fort San Marcos

A team of archaeologists led by University of South Carolina's Chester DePratter and UGA's Victor Thompson has located the remains of a Spanish fort erected in 1577 in the Spanish town of Santa Elena, on present-day Parris Island, S.C. For decades, attempts to find it have failed, and Fort San Marcos stayed hidden until new technology brought it to light: San Marcos is one of five Spanish forts built sequentially at Santa Elena over its 21-…

Measuring marine CO2 production

Near the ocean surface, sunlight causes the breakdown of organic compounds and converts them into carbon dioxide. Until recently, this process has been nearly impossible to measure because the additional carbon dioxide produced per day is tiny compared to the existing high concentration of CO2 present in the sea. But using a new technique and a new NSF grant, marine sciences researchers at the Skidaway Institute of Oceanography are working…

Greenland ice melting and arctic amplification

Clear skies and warmer weather in northern Greenland from this high-pressure system resulted in record setting surface temperature and meltwater runoff in the northwest. With less summer snow falling and melting underway, northern Greenland's reflectivity also decreased and the water absorbed more heat from the sun, further increasing melting.  It is unclear whether this set of circumstances will continue to hold true this summer, or in…

Climate Feedback

Not the feedback loop, but fact-checking media reports. In perhaps the next iteration of evaluating climate news and data, how trustworthy is the science you read about? A new group will track the accuracy of climate news to evaluate what's out there: Last week, Climate Feedback announced the Scientific Trust Tracker, a feature that will track news outlets’ accuracy on climate change, one scientist-reviewed story at a time. Right now,…

How plants respond to climate change

Jill Anderson, an assistant professor of genetics, has received a $1.1 million grant from the National Science Foundation Early Career Development Program to study the effects of climate change on plants. Among the NSF's most prestigious, CAREER awards support junior faculty who exemplify the role of teacher-scholar and the integration of education and research: Anderson's project tests whether plants will be able to survive on a warming…

UGA team travels to Gulf of Mexico to investigate May 12 oil spill

Marine scientist Samantha Joye organized a rapid response research cruise to assess the impact of a crude oil spill approximately 90 miles south of Timbalier Island, Louisiana: The U.S. Coast Guard responded to the spill reportedly discharged from a Shell subsea wellhead flow line on May 12. "Our goal for this response mission is to document the distribution of oil in the water column, to characterize the hydrocarbons and to assess the fate of…

Understanding the microbiomes

The White House Office of Science and Technology Policy hosted a May 13 event on microbiomes—communities of microorganisms that live on and in people, plants, soil, oceans and the atmosphere—featuring presentations from four scientists including UGA's Samantha Joye: Microbiomes maintain the healthy function of ecosystems, influencing diverse features of the planet from human health to climate change and food security. During the event, the…

Dawn Of the DAWGSat program

The time when UGA did not have a space program is soon to be ending, thanks to some truly ambitious and imaginative undergraduate students and an interdisciplinary faculty team: A University of Georgia project led by a team of undergraduate students and including faculty from the Franklin College of Arts and Sciences and the College of Engineering was recently selected for funding by NASA's CubeSat Launch Initiative. The UGA proposal, "CubeSat…

Tracking the Greenland meltwater

Very interesting work in the context of a significant increase in the melting of glacial land ice on the island of Greenland due to atmospheric warming: a team of researchers led by faculty at the University of Georgia has discovered the fate of much of the freshwater that pours into the surrounding oceans as the Greenland ice sheet melts every summer. They published their findings today in the journal Nature Geoscience. "Understanding…

Scientists discover new reef system at mouth of Amazon River

Marine sciences professor Patricia Yager is part of an incredible story of the unlikely discovery of a reef system near the mouth of the Amazon River: 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…

Watershed UGA

Urban watersheds represent one of the most complex and intractable environmental quandaries: overlapping jurisdictions, streets, property boundaries and buildings make it all but impossible to reclaim any relationship to a naturally existing water collection basin. Watersheds are drainage points for surface water to reach a river or other outlet and they are essential for the health of both land and water. The heart of the UGA campus sits in the…

Combined Symphony Orchestra and Choirs concert

Setting Whitman to music was something of an English tradition from the late 19th to early 20th centuries, and Williams was a notable participant. While [perhaps] not technically an Earth Week event, we have made it so. Our student orchestra and choirs are second-to-none, led by the best faculty that attract amazing musicians to campus to study and perform. Williams' great 'Sea Symphony' places our finest large ensembles in the vanguard of…

Study predicts impacts of sea level rise

Assessing the risk from rising seas using year 2100 population forecasts for all 319 coastal counties in the continental U.S., a new UGA study predicts that more than 13 million American homes will be threatened by rising sea levels by the end of the century: The study is based on analyses by Mathew Hauer for his doctoral work with the UGA Franklin College of Arts and Sciences; Deepak Mishra of the UGA department of geography; and Jason…

Attributing extreme weather events to climate change

Can extreme weather events - hurricanes, droughts - be linked to climate change? A new report from the National Academies of Sciences, Engineering and Medicine establishes for the first time that science can now estimate the influence of climate change on these extreme events: The findings, presented to White House and congressional leaders on March 10 by committee members who conducted the study and wrote the report, describes how the…

Deciphering Ocean Carbon

The complex unpacking of how micro-organisms work - and work together - in the world's oceans continues apace, as this new perspective article by marine sciences faculty members attests: In the past, studying the connections between ocean-borne compounds and microbes has been impractical because of the sheer complexity of each. Three University of Georgia faculty members-along with an international team of scientists-bring to the forefront…

Leap Year, explained

Professor Marshall Shepherd uses his Forbes column to embark on a perfectly understandable explanation of why we have seasons, the actual length of Earth's trips around the sun, et voilà, the need for a Leap Year: Throughout the year, different parts of the Earth receive the Sun’s rays more directly. In Boreal Winter, the Northern Hemisphere is tilted away from the Sun. At the same time, Austral Summer is happening because the Southern…
