Latest Data Releases

06/14/2019 – Data Release

Provisional SALTEx well logger monitoring data are available on the Project Data page through February 2019. The Schlumberger logger files were corrected for atmospheric pressure and sensor elevation for calculation of water level, and salinity and density were calculated from temperature and conductivity measurements.

04/26/2019 – Data Release

Two data sets investigating the effects of elevation on surface soil temperature gradients within salt marshes was added to the GCE Data catalog by Merrly Alber and Jessica O'Connell.

MSH-GCE0-1904: Variation in Landsat 8-estimated land surface temperature with elevation from Spartina alterniflora marsh cross sections in the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) site and Virginia Coast Reserve (VCR) LTER sites for winter and summer observations spanning 2013-2018

MSH-GCED-1904: Continuous soil temperature measurements at 10 cm depth from 3 month-long deployments in summer and winter within the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) site in 2017 and 2018

 

11/20/2018 – Data Release

Provisional SALTEx well logger monitoring data are available on the Project Data page through September 2018. The Schlumberger logger files were corrected for atmospheric pressure and sensor elevation for calculation of water level, and salinity and density were calculated from temperature and conductivity measurements.

GCE Project Announcements

07/29/2019 – Announcement

The Davidson Fellowship is an exciting new fellowship program for graduate students at the national estuarine research reserves. One two-year fellowship opportunity will be available at each of the 29 coastal sites.

07/24/2019 – Personnel News

Youzheng Zhang is back at Sapelo Island for a couple weeks. Youzheng worked with Steve Pennings in 2018--they published a paper on latitudinal patterns of wetland nematode communities in Chinese marshes dominated by Phragmites and Spartina alterniflora, and also sampled East Coast US marshes from Maine to Florida. This summer, Youzheng and Steve will start writing up the results of the 2018 survey.

07/24/2019 – Education News

Last week, 14 teachers gathered on Sapelo Island for the 2019 GCE-LTER Schoolyard program. If you were involved this year, you may have noticed things were a little different. Every participant was returning to the program, and for some this was their third time attending! With so much expertise at our fingertips, this year's program focused on evaluating what has been done up to this point, and how can we expand, integrate, and finetune GCE's education and outreach offerings. We received a lot of great feedback that we are hoping to incorporate, including updated teacher resources and an update to the GCE Education Program website. A big thank you to everyone who helped make this year's program a success!

The IU Wetlands Laboratory visited Sapelo Island July 8-12 2019 where they sampled porewater and measured soil redox at the SALTEx research site to better understand how the marsh is recovering from long-term salt water additions. They also visited the PredEx site where they collected soils for nitrogen and carbon analysis and deployed tea bags to measure decomposition rates. Their involvement in the PredEx experiment will allow for a better understanding of how excluding large salt marsh predators influences sediment carbon cycling.

The GCE project is contributing to the global, distributed Nutrient Network (NutNet) this year. NutNet participants collect descriptive data about plant communities at their sites, and some go on to experimentally add nutrients as part of a global fertilization experiment. We're doing the first part, sampling wetland plant communities along the entire salinity gradient from tidal fresh to salt marsh. At each site, we collect data on plant richness, composition, biomass and nutrient composition; soil salinity and nutrient content; the amount of light intercepted by the vegetation; and a few other variables. We hope to contribute around 150 plots worth of data, equivalent to around 5 "typical" NutNet sites. Our data will become part of the NutNet database, and be used in global studies of plant community ecology. We are also anticipating that the GCE data alone will be interesting enough to support a manuscript.

07/11/2019 – Award

Merryl Alber will receive the Margaret A. Davidson Award for Stewardship from the Coastal and Estuarine Research Federation at their meeting in November.  Congratulations to our noble leader, who is more than deserving of this award for her efforts to translate science into actionable management information.
