Latest Data Releases

06/19/2020 – Data Release

Peter Hawman in Deepak Mishra's lab submitted four data sets including eddy covariance analysis from the GCE-LTER flux tower and the Mishra flux tower at the Grand Bay NERR site in Mississippi as well as leaf area index data from the sites:

MSH-GCET-2006: Eddy covariance 30-minute CO2 fluxes with accompanying biophysical variables from the GCE-LTER flux tower site from December 2018 to January 2020

MSH-NASA-2006: Eddy covariance 30-minute CO2 fluxes with accompanying biophysical variables from the Grand Bay, Mississippi flux tower site from March 2018 to January 2019

PLT-NASA-2006a: Leaf area index for Spartina alterniflora near the GCE-LTER Flux Tower in 2018 and 2019

PLT-NASA-2006b: Leaf area index and above ground biomass for Juncus roemerianus in the Grand Bay National Estuarine Research Reserve from 2015 to 2019

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

GCE Project Announcements

12/19/2020 – Field Program News

GEC Techs Dontrece Smith and Elise Diehl along with affiliated investigator Lori Sutter visited GCE monitoring sites to measure sedimentation and soil surface elevation elevation and to clean sondes. Lori will be taking over the SET and feldspar measurements as Chris retires and bikes off into the setting (or is it rising) sun. Photos are from tidal forest site and one of the marshes. Can you guess which one?

If anyone knows a K12 teacher who teaches in Spanish, we'd like to partner with one or two teachers to use the Spanish language version of The Adventures of Jacob in their classroom this coming semester. We'll provide books for the students, and make virtual visits to the classroom. Put them in touch with Steve Pennings.

There's still time to order copies of Jacob the Technician in English or Spanish and get them in time for Christmas. Email Steve Pennings for prompt and courteous service.

GCE members from Indiana University and the University of Georgia published an article in L&O Letters, an open access journal, invetigating the effects of press versus pulse saltwater intrusion on microbial communities of a tidal freshwater marsh.

A PBS film crew from South Florida was on Sapelo this past week filming the GCE-LTER team in action for an episode of the "Changing Seas" series that will focus on salt marshes. If we don't end up on the cutting room floor, the show will air early next summer.

10/28/2020 – Personal Observation

GCE scientists are so focused on the marsh that many of us may not realize that there are two species of Littoraria on Sapelo Island. In addition to the marsh periwinkle, Littoraria irrorata, that we all know and love, there is a second species, Littoraria nebulosa, the cloudy periwinkle. L. nebulosa is found throughout the Caribbean and on the East Coasts of North and South America. Its preferred habitat is wood. On Sapelo Island you'll find it on the North ends of Nannygoat beach and Cabretta beach where eroding shores have dumped trees into the intertidal along the beach. Many of these trees in the intertidal have abundant L. nebulosa populations living on them. If you handle them, they emerge from their shells and crawl around much more readily than L. irrorata does, proof of their trusting and friendly nature.
