Latest Data Releases

09/25/2017 – Data Release

Data from the Schlumberger groundwater well loggers deployed at the SALTEx research site have now been updated through 04-Aug-2017. Two loggers are deployed in the SALTEx well measuring water pressure, salinity and temperature - one deployed at the well bottom and one near the surface. The well pressure data are corrected for atmospheric pressure and converted to water level in meters relative to NAVD88 based on RTK-GPS elevation of the logger and well metrics. Provisional data and plots are available on the private GCE website here, and finalized data sets will be added to the GCE Data Catalog in the coming months.

09/22/2017 – Data Release

Two new Duplin River Radon activity data sets were added to the GCE Data Catalog by Rick Peterson, including results from ongoing Radon monitoring studies conducted from 2012-2016 ("Radon Activities in the Duplin River near Sapelo Island, Georgia") and a 2016 transect survey ("Radon Surveys in the Duplin River near Sapelo Island, Georgia from July 2016").

08/14/2017 – Data Release

The data set GEL-GCET-1216 (Effects of Small-scale Armoring and Residential Development on the Salt Marsh/Upland Ecotone in Coastal Georgia, USA) by Alyssa Gehman et al. was added to the GCE Data Catalog. This data set includes results from extensive shoreline armoring surveys conducted in June-July 2013 as part of Alyssa's PhD research.

09/24/2017 – Monitoring Program

Tropical Storm Irma may not have hit Sapelo Island directly, but the strong sustained northeasterly winds with gusts to 70mph hit the island near spring tide, piling up water in the sounds and resulting in water levels 0.5-1m above those during Hurricane Matthew in October 2016. Many UGAMI buildings and field sites experienced significant flooding for the first time in many decades, and the dunes at Nannygoat beach were decimated (see the dramatic YouTube video by Rachel Guy at SINERR, and GCE flux tower damage observed by the field crew).

09/22/2017 – Research News

The GCE flux tower sustained some damage from Irma. Boardwalks were damaged, solar panels knocked over and submerged, some of the lower electronics were submerged, batteries were submerged and discharged, and the rain gauge damaged. Some of the instruments may still be functioning, but the tower needs a complete overhaul in order to resume full operations.

08/23/2017 – Announcement

From September 2016 to June 2017, NOAA conducted a needs assessment to identify how the synthesis and analysis of NERR System Wide Monitoring Program (SWMP) data can better address priority coastal and estuarine management questions at national, regional, and local levels. The results of the needs assessment are intended to help NOAA and the reserve system guide investments in research, education products, and training activities for coastal decision-makers and demonstrate the value of investing in long-term monitoring efforts such as SWMP.

Brendan Manley is the newest addition to the GCE field crew.  He finished with a MS in Environmental Studies at UNC Wilmington in December.  He has been gaining field experience working with the North Carolina Coastal Reserve and National Estuarine Research Reserve.   Brendan is also currently in the United States Air Force Reserves after spending 10 years in the United States Air Force.  Please make sure you say hello to Brendan the next time you are on Sapelo.

07/13/2017 – Outreach News

A group of 13 enthusiastic teachers have gathered at UGAMI once again to spend a week assisting Scientists and Graduate Students in the field. The 13 teachers, including 2 from Tennessee, have been deeply immersed in the field work for the various projects supporting the mission and goals of the GCE-LTER. It is a great testimony to the Schoolyard program that both teachers and scientists arrange their summer to return to the island to work on their projects during this particular time. This year we have 3 returning teachers acting as mentors for the newbies. The Alber, Schalles, Pennings, and Craft teams are back and going strong. Some of the projects involve water quality, plant monitoring, sea turtle patrol, spider population studies, and, of course, some aspect of SALTEX. Teachers are experiencing many different stages of the processes of science with intentions of reflecting the same in their own teaching settings. It is certainly not always fun and games, but the groups that gather each year make the most of the experiences and always go away with great stories to tell, a smile and the hope of returning.

07/11/2017 – Education News

Scientists working at Sapelo have not always managed to clean up after themselves. Schoolyard teacher Mary Beth Hannon and Steve Pennings took a break from collecting data on plant communities to clean up part of a long-abandoned experiment at airport marsh. We won't name and shame the scientist who left it here (not part of our beloved LTER family!), but with more and more attention being paid to work in the Georgia marshes, it is important for us all to clean up in the future when our experiments are finished.
