October 2001 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Sapelo River transect
Three hydrographic surveys were performed on October 13 and October 14, 2001, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at approximately 3km intervals from 0km to 36km during various tidal regimes. Conductivity, temperature, pressure, optical back scatter, photosynthetically-available radiation, oxygen and chlorophyll a fluorescence were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected during the upcast were deleted. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
October 2001 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Altamaha River transect
Eight hydrographic surveys were performed from May 30 through June 4, 2001, along an east-to-west transect up the Altamaha River in Georgia (Altamaha River Transect, GCE-AL). Vertical CTD profiles were collected at 1-2km intervals from 2km east of the line of demarcation (station -02) to 28km upriver along the transect during flood and ebb tidal regimes. Conductivity, temperature, pressure, optical back scatter, photosynthetically-available radiation, oxygen and chlorophyll a fluorescence were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected during the upcast were deleted. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.
November 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Doboy Sound transect

Surface water DIC, total alkalinity, and pH for the September 2002 through December 2004 Georgia Coastal Ecosystems LTER oceanographic surveys
Surface water samples for total dissolved inorganic carbon (DIC), total alkalinity (TAlk), and pH were collected from the Altamaha River, Doboy Sound, Sapelo River and the Duplin River (anchor station near Marsh Landing) during the Georgia Coastal Ecosystems LTER oceanographic surveys from September 2002 through December 2004. DIC was measured using a custom automated DIC analyzer. Total alkalinity was determined by Gran titration. pH of surface water at stations was measured on board using a glass electrode. This study was part of the GCE oceanographic monitoring program, and will be repeated periodically.

Population Study of Geukensia demissa and Ilyanassa obsoleta at the Georgia Coastal Ecosystems LTER site in April 2008
During the dates of April 21-April 23, 2008, we conducted surveys to determine the relative abundance of ribbed mussels (Geukensia demissa) and mud snails (Ilyanassa obsoleta) across Spartina height zones. Surveys were performed at each of the GCE long term sites (GCE1-GCE10) and were comprised of transect and quadrat sampling methods. Quadrats measured 25 cm^2 for mud snails and 1 m^2 for ribbed mussels. Ribbed mussel surveys consisted of both transect and quadrat methods. For ribbed mussels, a total of 10 quadrats were randomly placed in tall-, mid-, and short-form Spartina and number of visible mussels counted. Transects for ribbed mussels measured 50 m x 2 m and were performed in intermediate- and short-form Spartina zones. In each transect, we counted observed number of mussel clumps per transect. For mud snails, a total of 10 quadrats were randomly placed in tall- and intermediate-form Spartina and on mud banks (2 m from Spartina edge along the creek bank) and total number of individuals per quadrat were counted.
