A consortium of universities headed by UGA will continue ecological field research on the marshes and estuaries of the Georgia coast following the renewal of a six-year, $5.8 million grant from the National Science Foundation. The award will help scientists understand how these ecosystems function, track changes over time and predict how they might be affected by future variations in climate and human activities.
“Discerning long-term trends in natural systems requires careful scientific analysis over the course of many years,” said Merryl Alber, Georgia Coastal Ecosystems Long-Term Ecological Research project manager and professor of marine sciences in the Franklin College of Arts and Sciences.
The NSF award extends the research project, which began in 2000. The research is conducted out of the UGA Marine Institute on Sapelo Island and builds on the institute’s rich tradition of ground-breaking ecological research.
GCE scientists are studying the long-term effects of climate change, sea level rise and human alterations of the landscape on the unique ecosystems found in the estuaries, sounds and marshes surrounding Sapelo Island in McIntosh County.
“The citizens of Georgia receive many benefits from coastal ecosystems,” said Alber. “Understanding the health of these systems is not just interesting from a scientific point of view, but also of practical importance.”
This latest renewal of the Georgia coastal ecosystems project will provide support through 2018. In that time, more than 30 UGA researchers, along with partners from more than a dozen other academic institutions and agencies, will continue to accumulate and analyze data relating to plant and animal populations, water chemistry, carbon cycling and many other important environmental indicators.
There are cycles in nature that take significant investment of time to fully -understand, and the traditional two- or three-year scientific grant is not always sufficient, according to Alber. It is a rare opportunity for researchers to examine this site over such an extended period, she said.
“We already have 12 years of data, so when people wonder if new events or new patterns are out of the ordinary, we can answer those questions,” she said. “The only way to put new events in perspective is to have long-term data.”
Members of the project also are involved in a number of education and outreach initiatives. Graduate students from UGA and other universities conduct fieldwork at the site, and many have published dissertations and scientific papers based on their research. The program also sponsors research opportunities for undergraduate students.
In partnership with the UGA Marine Extension Service, the project runs a schoolyard program to train K-12 educators in field ecology and hands-on research activities that can be used in the classroom.
