11/14/2014 – Monitoring Program

As previously reported, the GCE-LTER program deployed an eddy covariance flux tower in the marsh off the Duplin River in July 2013, measuring a wide range of atmospheric, soil and aquatic variables. We also installed a camera on this tower in September 2013 to measure changes in marsh vegetation as part of the PHENOCAM Network. While these efforts are starting to yield exciting research findings, they are also illustrating just how difficult it can be to deploy and maintain advanced instrumentation in a living marsh ecosystem.

10/16/2014 – Monitoring Program

Fall monitoring is underway. The GCE technicians and representatives from the Pennings, Alber, Silliman and Angelini labs are monitoring soil, plants and invertebrates at the core GCE sites. We're up to 15 years of data for some of these measurements, so it is becoming a wonderful time series.

10/09/2014 – Monitoring Program

Update 21-Oct-2014: The communications problem is actually due to a faulty GOES satellite transmitter. SINERR has ordered a replacement, and data will continue to be downloaded manually until telemetry can be restored.

The GOES satellite uplink for the SINERR/GCE weather station at Marsh Landing started to fail at the end of September. The problem has been traced to a faulty communications cable, and a replacement is currently on order. The data are still being logged, and will be downloaded from the logger manually until the situation is resolved. In the mean time, near-real-time weather and hydrographic data from Hudson Creek at Meridian Landing are displayed on the GCE website home page to provide information on current site conditions.

09/09/2014 – Software Release

We are pleased to announce that version 3.9.0 of the GCE Data Toolbox for MATLAB is now available for download. This release represents a major milestone, marking the completion of a 10 year goal to provide native support for Ecological Metadata Language (EML) XML metadata in the toolbox. Complete EML data and metadata packages can now be generated from metadata and data content in GCE Data Structures, including optional mapping of local units to the EML Unit Dictionary or user-managed custom unit definitions. It is therefore possible to archive data sets created using the toolbox in the LTER Data Portal or another EML-compatible data repository directly, without using a separate metadata management system or XML editor.

With EML package export support, the GCE Data Toolbox can now be used as a complete data synthesis environment for the LTER NIS and PASTA framework. EML-described data packages can be retrieved from the LTER Data Portal and processed using the toolbox, then products can be packaged and exported as new EML-described data sets, all without manual XML editing. The EML support functions are modular, so EML-compatible attribute lists, data table descriptors or complete EML documents can be generated in workflows depending on the use case.

Software download and installation information is available at https://gce-svn.marsci.uga.edu/trac/GCE_Toolbox/wiki/Downloads

General information and support resources for the GCE Data Toolbox are available at https://gce-svn.marsci.uga.edu/trac/GCE_Toolbox

09/08/2014 – Coastal News

With funding provided by the Georgia Department of Natural Resources and logistical support from Gray's Reef National Marine Sanctuary, researchers from Georgia Southern University will release 50 gallons of fluorescent red dye (rhodamine WT) into the Altamaha River outflow on September 9, 2014. The plume of dye that results will be monitored visually and with instrumentation as it flows from the release point (just south of Wolf Island) along the Georgia coast and offshore. Tracking the path of the dye will provide estimates of the extent to which the Altamaha River delivers dissolved substances, both contaminants and nutrients, north and south along the Georgia coast and to hard-bottom reefs, such as Gray's Reef National Marine Sanctuary, occurring up to 20 miles offshore.
