Continuous salinity, temperature and depth measurements from moored hydrographic data loggers deployed at GCE2_Hydro (Four Mile Island, Georgia) from 01-Jan-2004 through 31-Dec-2004
Conductivity, temperature and pressure were measured continuously at Georgia Coastal Ecosystems LTER sampling location GCE2_Hydro (Four Mile Island, Georgia) from 01-Jan-2004 through 31-Dec-2004; however, data from 24-May-2004 through 23-Aug-2004 were lost due to instrument failure. Observations were logged at 30 minute intervals by moored Sea-Bird Electronics MicroCAT 37-SM data loggers and downloaded approximately bimonthly. Salinity, depth and sigma-t were calculated from the measured parameters using standard UNESCO algorithms. This data set was collected as part of the GCE-LTER Project continuous salinity, temperature and water level monitoring program.

Summer 2007 crab population survey based on crab hole counts in fifty-four GCE LTER Hammock sites and four GCE LTER study sites
Crab abundance was investigated at fifty-four hammock sampling sites and four Georgia Coastal Ecosystems (GCE) LTER study sites in June-July 2007 by counting crab holes as a proxy measurement. Each hammock site had six permanent study plots which were previously laid out. Crab holes were counted within a random location inside those six plots at each hammock. Crab holes were counted within a 625 cm^2 area and species were not differentiated in the count, but noted. This method estimates total crab abundance in each study site.

Experimental wrack disturbance at four times during the growing season
Using a field experiment on the Georgia coast, we simulated the effects of wrack disturbance on the marsh grass Spartina alterniflora. We simulated wrack disturbance on four different dates by covering selected plot with 10 cm of wrack collected nearby on March 18, May 27, July 15 or September 7. Wrack was fixed to the marsh surface with string so that it could not wash away. We also simulated the mechanical disturbance created by wrack but without the input of organic matter by clipping selected plots at the soil surface on the same dates. We measured plant heights in a 50 cm×50 cm quadrat centered in each plot before the first treatments were conducted in March, again on May 9, and every two weeks thereafter until plots were harvested. We also recorded the status of flowering in the late of the growing season.The center 50 × 50 cm of each plot was harvested by clipping stems at the soil surface on October 5-6, 2015. We measured the height and flowering status of each stem, and counted the number of stem-boring insects present in each stem by splitting the stem open. Data include plant height, flowering status and stem bored status.

PIE LTER stream chemistry characteristics studied for methane ebullition at four headwater streams in Massachusetts and New Hampshire.
Sediment, stream, and canopy characteristics were measured in four headwater streams in Massachusetts and New Hampshire associated with methane ebullition monitoring. Canopy cover, water depth, sediment organic matter content, the percent sediment less than 2mm in diameter, sediment depth, sediment percent carbon, and sediment percent nitrogen were measured.
