Latest Data Releases

06/04/2015 – 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 were also added to the GCE Data Catalog as additional downloads for all new and existing sonde data sets. More information about GCE moorings is available at http://gce-lter.marsci.uga.edu/public/research/mon/sounds_creeks.htm.

06/24/2015 – Website Addition

Background and logistical information for the June 2015 NSF site review of the GCE-LTER program is available on the private website at https://gce-lter.marsci.uga.edu/private/app/project_meetings/review_2015.asp. All GCE personnel participating in the review should visit this page to familiarize themselves with the agenda and other documents linked there when planning their travel and preparing their presentations.

A new search form is now available on the GCE Home Page that allows web visitors to limit searches to only publications, data sets, documents, imagery or locations if they are looking for something specific. These specialized searches are routed to the relevant GCE database (e.g. Bibliography, Data Catalog, etc.), and search results can then be revised or fine-tuned using the associated options. A general website search option is also available that routes searches to a Google Custom Search Engine configured for GCE-LTER.

One of the major goals for standardizing on Ecological Metadata Language (EML) to document LTER data sets was to facilitiate computer-mediated data analysis. Towards this goal, John Porter (VCR) and Wade Sheldon (GCE) collaborated in 2012 to develop tools that automatically transform EML metadata documents into runnable script code for loading the described data tables into R, SAS, SPSS or MATLAB for analysis. The scripts are annotated with descriptions of the data set and include all the commands required to download the files from the Internet and load the data values into the respective software (e.g. as R data frames or MATLAB arrays), dramatically simplifying the process for users. The scripts can also be saved, providing investigators with a means to download the same version of the data files in the future for re-analysis and for documenting their analytical workflow, two key elements of analytical reproducibility.

Graduate student Andrew Howard from UH measures clonal architecture of marsh plants to parameterize the clonal plant model. Andy is working with Marc Garbey and Steve Pennings on a clonal plant model to describe mixed communities of salt marsh plants. He's spending the month of June at Sapelo to learn what the plants actually look like and how they behave so that the model is as realistic as possible. Undergraduate Jonathan Adams from UH records data.

Data from the SINERR Lower Duplin YSI sonde (moored to a piling on the Marsh Landing pier) are now available in the GCE Data Portal. Long-term data were requested from the NERR Centralized Data Management Office (CDMO) and transformed for compatiblity with GCE monitoring data sets (e.g. UTC time and units) and distribution formats. Yearly and long-term data sets and plots were then added to the portal from 1999 to the present at native 15-30 minute frequency and aggregated to daily intervals. A data harvester application was also deployed that will retrieve new data semi-hourly from the NOAA HADS server to provide near-real-time data sets and plots on the portal.

A new, simplified version of the GCE Location Search web page is now online that allows geographic bounds to be specified using an embedded Google Map. This page can be used to create tables and maps of registered point locations across the GCE domain, matched by name, location type, parent site and geographic boundaries.
