Latest Data Releases

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.

09/02/2016 – Data Release

Data Set NUT-GCES-1608 (Porewater chemistry measurements from the GCE-LTER Seawater Addition Long-Term Experiment (SALTEx) - Chris Craft) has been added to the GCE Data Catalog.

GCE Project Announcements

09/15/2016 – Outreach News

This week we installed an outdoor wireless webcam on the seawater system pump bridge near the UGA Marine Institute, and registered the camera at Weather Underground to provide public access. Images are uploaded every 5 minutes to provide near-real-time views of the tidal creek and marsh to accompany the current weather report. The UGAMI WUG webcam page is available here, and links will be added to the new UGAMI website that is currently under development. The latest image is also displayed on the Current Conditions page of the GCE website, and images are archived by year and month every 15 minutes for future reference here.

09/13/2016 – IM News

As science has moved into the digital realm the need for unique identifiers for referencing research products, such as publications and data sets, has become critical. This requirement led to broad adoption of the Digital Object Identifier (DOI) system, an ISO standard for persistently identifying digital assets. DOIs are now standard fare in research practice and have been fully integrated into the LTER Network and GCE Information Systems for several years. Now the need for unique identifiers for research personnel has emerged as the next big challenge, so that research products and workflows can be properly attributed to the people who created them.

Earlier this year the GCE IM Office began accepting research protocol documents as part of the methods metadata for new data submissions (see IM FAQ). We have now finished adding complete support for protocols in the GCE Information System, so all associated protocols are fully described in data set metadata and can be downloaded by data users. We have also added a dedicated "Protocols" section to the GCE File Archive under Documents/Procedures for managing versioned protocol documents, and added links to these documents on data set summary pages in the GCE Data Catalog (e.g. see the latest SALTEx data set NUT-GCES-1608).

09/02/2016 – Website Addition

Over the past few years NSF program officers and reviewers alike have begun to place major emphasis on both online data availability and evidence of long-term data use when reviewing LTER sites and LTER proposals. For example, LTER reviewers often search site data catalogs for specific data sets referenced in prominent journal publications to verify data availability. However, inconsistencies in data citation practices in the scientific literature, particularly before data set DOIS were available, has hampered this process and lead to significant under-representation of LTER data in published research.

The SALTEx group published a brief, "Climate Change and the Fate of Coastal Wetlands", in Wetland Science and Practice, a publication of the Society of Wetland Scientists.

The International LTER Network (I-LTER) is establishing an online repository of research sites and datasets to serve as a portal for their sprawling 600-site network. As part of this effort they have asked US LTER sites to provide detailed site profiles for inclusion, and we have now registered the GCE-LTER site in this database (see our entry here). Hopefully this will become a useful resource for discovery of long-term environmental research programs and datasets, and lead to more international collaborations in the future.
