Latest Data Releases

10/06/2016 – Data Release

Long-term integrated salinity, temperature and pressure data sets from GCE MicroCAT sonde moorings near sites GCE1, GCE2, GCE3, GCE6, GCE7, GCE8, GCE9, GCE10 and GCE11 are now available in the GCE Data Catalog. Data set PHY-GCES-1610 contains original 30 minute interval observational data covering the full period of record at each mooring through December 2015, representing nearly 2 million salinity and temperature observations across the GCE domain. Separate data downloads are provided for each site in compatible formats. Data set PHY-GCES-1610b contains daily-summarized data sets based on 30 minute data with invalid values removed and basic gap-filling. A comparable monthly data set that includes more comprehensive gap-filling is also under development. These data sets will be updated annually to include data from the prior year.

09/23/2016 – Data Release

Finalized salinity, temperature and pressure data from GCE MicroCAT sonde moorings near sites GCE1, GCE2, GCE3, GCE6, GCE7, GCE8, GCE9, GCE10 and the new GCE11 freshwater tidal forest site in the Altamaha River are now available in the GCE Data Catalog and GCE Data Portal. In addition to the original 30-minute-interval data, daily-summarized data files are also available as additional downloads for all sonde data sets. More information about GCE moorings is available at http://gce-lter.marsci.uga.edu/public/research/mon/sounds_creeks.htm.

09/20/2016 – Data Release

A long-term plant monitoring data set (PLT-GCES-1609) has been added to the data catalog, combining the annual plant biomass monitoring data sets from 2000 to 2015. This synthetic data set includes both the original stem count, shoot height and biomass observations by site, species, marsh zone and plot as well as two summary data tables. This data set will be updated annually as new monitoring data are processed, along with additional long-term integrated data sets from the GCE marsh and hydrographic monitoring programs.

GCE Project Announcements

12/01/2016 – Research News

The LTER network features a rotation of stories about all the LTER sites. Right now they are featuring a story about the GCE that is focused on the recent fall monitoring and some of what we've learned about controls on Spartina productivity.  https://lternet.edu/fall-monitoring-GCE

11/16/2016 – Publication News

The GCE Collected Reprint Library has now been updated to include publications submitted to the GCE Bibliography through October 2016. This archive contains all available reprints of published work supported by the GCE-LTER research program, including journal articles, book chapters, PhD dissertations, and MS/MA theses. The archive can be browsed online from the private GCE website, or downloaded to your computer as a Zip archive.

11/11/2016 – Announcement

The GCE Year 4 Annual Report was submitted to NSF last week. It details progress on the project objectives, highlights some of our key accomplishments, provides updates on information management, outreach, and training, and lists publications from the past year. Check it out at:

10/31/2016 – Monitoring Program

Now that fall monitoring is in the rear view mirror (mostly; Merryl and Jacob are knocking out the last bit today), the winter season has arrived at Sapelo. It is unusual this year because we're still picking up debris and repairing instruments damaged by hurricane Matthew. And the technicians are scrambling to catch up and keep up with the SALTEX and high marsh experiments, mini-cruises, and all the other routine work. Winter is usually the "down time" for the project, when the techs catch up on everything that has gone un-done during the year, but this winter will be less down than usual due to the disruption of the hurricane.

10/29/2016 – Research News

GCE fall monitoring for 2016 is completed! We were a bit behind and short handed due to hurricane Matthew, but we had help from Adam Sapp and volunteers Andy Penniman and Gustavo Fuentes. The weather cooperated, with beautiful clear days, and we knocked out the work on schedule. All the vegetation at one of our secondary sites had been flattened by a huge mat of wrack that the hurricane storm surge pushed up into the marsh, but all the other sites showed remarkably little signs of the storm.

10/15/2016 – IM News

This week we registered a new study site in the GCE Information System to describe the geographic scope of research conducted at or near the eddy covariance flux tower: GCE_Flux. The new site includes the Spartina marsh around the tower bounded by the Duplin River on the west and Barn Creek on the south and east, and is included on the GCE Sampling Sites map page. Please use this new site designation when submitting flux tower-related data or survey data that include flux tower marsh samples unless explicit geographic coordinate data columns are included (i.e. latitude and longitude or UTM easting and northing).
