GCE Project Announcements
08/13/2008 – Research News
The Marsh Landing weather station was struck by lightning on August 9. Several sensors and the satellite transmitter were damaged and replacements are being obtained. The station will be brought back online as soon as possible.
The real-time weather display on the GCE website home page will be switched to Hudson Creek at Meridian until data access is restored for Marsh Landing.

Chris Craft, Steve Pennings and colleagues describe differential responses of tidal marsh area and delivery of ecosystem services to rising sea level in a new paper published in Frontiers in Ecology and the Environment. The major finding is that losses of marsh acreage with sea level rise do not necessarily lead to equivalent losses in marsh function, because different types (fresh, brackish, salt) of marsh have different levels of function, and are predicted to be lost at different rates.
A more complete description of the study is available online in the GCE document archive at http://gce-lter.marsci.uga.edu/public/app/resource_details.asp?id=267

07/25/2008 – Software Release
Version 2.95 of the GCE Data Toolbox for MATLAB is now available for GCE member and public download. New functions are available for aggregating time-series data along a moving date/time window to smooth out data series and produce more reasonable loading averages for flux calculation.

07/23/2008 – Coastal News
High-tech equipment recently installed on wells now provides daily information to better protect Brunswick, GA against saltwater contamination. The fresh-water supply in a two-square mile area near Brunswick, Ga. is contaminated from saltwater.
The U.S. Geological Survey (USGS) designed and recently installed an innovative measurement system using satellite telemetry to enable daily monitoring of the area of contamination. This new equipment will monitor against further contamination to any surrounding fresh ground-water resources.
These real-time-monitoring wells are part of a larger network of wells that the USGS samples for chloride concentration on an annual basis to determine relative movement of saltwater in the Upper Floridan aquifer in the Brunswick area. Ground-water levels and chloride concentrations in Brunswick-Glynn County have been monitored since the late1950s as part of the Brunswick-Glynn County Cooperative Water Program.
Data about these and other well sites is available at:

07/11/2008 – Announcement
A new mailing list is now available for GCE GIS users (gcegis-l@listserv.uga.edu). This list will be used for announcements about planned maintenance or changes to reference data on the GCE Geodatabase server, GCE ArcGIS license server updates, availability of new ESRI software products in the GCE IM office or at UGAMI, and other matters relevant to GIS/GPS on the GCE project.
Please contact John Carpenter or Wade Sheldon to subscribe to this mailing list.

04/26/2008 – Website Addition
The GCE Data Portal web pages (http://gce-lter.marsci.uga.edu/portal/monitoring.htm), providing access to near-real-time and historic monitoring data from GCE and affiliated programs, were redesigned using XML/XSLT technology. This change allows the MATLAB-generated data set summary, detail and plot pages to be archived as pure data files in XML format, with XHTML web display and styling provided by shared XSLT and CSS files stored on the GCE web server when each file is viewed in a web browser. This change will permit future updates to GCE web design, navigation menus and styling to be accomplished without changes to the underlying data files.
As part of this redesign, separate plot pages are now generated for every archived data set instead of only the highest temporal resolution data for a given time period. Preview plots are therefore available for multiple temporal resolutions per time period for most stations (e.g. 15-minute, daily, and monthly resolutions).
