Latest Data Releases

09/25/2017 – Data Release

Data from the Schlumberger groundwater well loggers deployed at the SALTEx research site have now been updated through 04-Aug-2017. Two loggers are deployed in the SALTEx well measuring water pressure, salinity and temperature - one deployed at the well bottom and one near the surface. The well pressure data are corrected for atmospheric pressure and converted to water level in meters relative to NAVD88 based on RTK-GPS elevation of the logger and well metrics. Provisional data and plots are available on the private GCE website here, and finalized data sets will be added to the GCE Data Catalog in the coming months.

09/22/2017 – Data Release

Two new Duplin River Radon activity data sets were added to the GCE Data Catalog by Rick Peterson, including results from ongoing Radon monitoring studies conducted from 2012-2016 ("Radon Activities in the Duplin River near Sapelo Island, Georgia") and a 2016 transect survey ("Radon Surveys in the Duplin River near Sapelo Island, Georgia from July 2016").

08/14/2017 – Data Release

The data set GEL-GCET-1216 (Effects of Small-scale Armoring and Residential Development on the Salt Marsh/Upland Ecotone in Coastal Georgia, USA) by Alyssa Gehman et al. was added to the GCE Data Catalog. This data set includes results from extensive shoreline armoring surveys conducted in June-July 2013 as part of Alyssa's PhD research.

01/05/2018 – Website Addition

As mentioned previously, NSF is now placing particular emphasis on ensuring data referenced in published papers are archived and available online. However, few GCE publications currently contain links to data sets, making it hard for us to demonstrate we are meeting this expectation.

12/30/2017 – Website Addition

Over the past decade NSF has dramatically increased requirements for managing and archiving research data in RFPs for both new and renewing grants. In particular, program officers have been looking for evidence that the data behind major publications cited in annual reports and renewal proposals are archived and available online. For LTER programs there are additional expectations to demonstrate use of long-term data in publications and research design.

Weather Underground terminated their WeatherCam upload service on Nov 1, 2017, interrupting our access to images recorded by the Creek Cam deployed behind the UGA Marine Institute. We have now set up our own local FTP service, and re-established uploads on Nov 27, 2017. The latest image can be viewed on the GCE Current Conditions web page, and historic images can be browsed by year and month at http://gce-lter.marsci.uga.edu/ugami/creekcam/.

Abstract: Governments worldwide do not adequately protect their limited freshwater systems and therefore place freshwater functions and attendant ecosystem services at risk. The best available scientific evidence compels enhanced protections for freshwater systems, especially for impermanent streams and wetlands outside of floodplains that are particularly vulnerable to alteration or destruction. New approaches to freshwater sustainability — implemented through scientifically informed adaptive management — are required to protect freshwater systems through periods of changing societal needs. One such approach introduced in the US in 2015 is the Clean Water Rule, which clarified the jurisdictional scope for federally protected waters. However, within hours of its implementation litigants convinced the US Court of Appeals for the Sixth Circuit to stay the rule, and the subsequently elected administration has now placed it under review for potential revision or rescission. Regardless of its outcome at the federal level, policy and management discussions initiated by the propagation of this rare rulemaking event have potential far-reaching implications at all levels of government across the US and worldwide. At this timely juncture, we provide a scientific rationale and three policy options for all levels of government to meaningfully enhance protection of these vulnerable waters. A fourth option, a 'do-nothing' approach, is wholly inconsistent with the well-established scientific evidence of the importance of these vulnerable waters.

A paper questioning the "rosy" assumptions of a group of coastal scientists regarding the ability of tidal marshes to compensate for climate change-driven sea-level rise through accreting or building elevation was recently published in Nature Climate Change. The article can be viewed online here.
