Abstract: Conductivity, temperature and pressure were measured continuously at Georgia Coastal Ecosystems LTER sampling location GCE8_Hydro (Altamaha River near Aligator Creek, Georgia) from 01-Jan-2013 through 31-Dec-2013. Observations were logged at 30 minute intervals by moored Sea-Bird Electronics MicroCAT 37-SM data loggers and downloaded approximately semi-monthly. Salinity, depth and sigma-t (density anomaly) 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. 3. Study Type: Monitoring 4. Study Themes: Physical Oceanography 5.

Funding Period: 01-Nov-2012 to 01-Nov-2018 4. Objectives: The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. 5. Abstract: The Georgia Coastal Ecosystems (GCE) LTER is located along three adjacent sounds on the Atlantic coast and includes both intertidal marshes and estuaries. Long-term drivers of climate change, sea level rise and human alterations of the landscape will cause transitions in dominant habitat types (state changes) within the GCE domain by changing the amounts and patterns of water delivery across the landscape. These changes in water delivery can be conceptualized as presses and pulses in river inflow, local runoff, groundwater input, and tidal inundation, which will in turn manifest themselves as changes in salinity and inundation patterns in the domain. The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. The goals are to: 1) Track long-term changes in climate and human actions in the watershed and adjacent uplands, and evaluate the effects of these drivers on domain boundary conditions. 2) Describe temporal and spatial variability in physical, chemical, geological and biological, and to evaluate how they are affected by variations in river inflow and other boundary conditions. 3) Characterize the responses of three dominant habitats in the domain to pulses and presses in salinity and inundation. 4) Describe patterns of habitat provisioning and C sequestration and export in the GCE domain, and to evaluate how these might be affected by changes in salinity and inundation. These efforts will be synthesized into a synoptic understanding of both biotic and ecosystem responses to variations in salinity and inundation driven by climate change and human activities, which will be used to assess thresholds between habitats and the potential for state changes in the domain. 6.

Experimental or Sampling Design a. Design Characteristics: Conductivity, temperature and pressure were continuously monitored using an autonomous data-logging sensor package (sonde) that was moored to a piling and submerged 1-1.5m below mean low water. b. Permanent Plots: none c. Data Collection Duration and Frequency: The MicroCAT was programmed to autonomously measure and log conductivity, temperature and pressure at a sampling rate of 30 minutes (based on its internal chronometer). Upon retrieval the data was downloaded from the instrument via RS-232 serial communications and processed using custom Matlab(r) procedures to calculate depth (i.e. from pressure and latitude), salinity and sigma-t (i.e. from conductivity and temperature), and date and time components from sample time stamps. Beginning of Observations: 01-Jan-2013 End of Observations: 31-Dec-2013 3. Research Methods a. Field and Laboratory Methods: Deployment -- The MicroCAT was mounted inside a protective PVC pipe enclosure and attached to a wooden piling (~12 inch diameter) that was driven firmly into the substrate. The enclosure was constructed from a 10-foot length of 6-inch (internal diameter) PVC pipe that was perforated all over by drilling 1.5-inch holes (at approximately 4-inch spacing); this permits proper water circulation within the enclosure. The bottom of the PVC pipe was submerged about 5 feet below the water surface at low tide and bolted (vertically) to the piling. The MicroCAT was deployed by lowering it into the enclosure on a 0.375-inch stainless steel cable, and bolting the cable to the piling, so that the bottom of the data logger was ~3 inches above the bottom of the PVC pipe. A weighted surveyor's tape was then used to measure the distance from the substrate to the pressure sensor on the MicroCAT for calculation of total water column depth from pressure readings. The mooring was inspected every 1-3 weeks, and any visible fouling of the enclosure or MicroCAT was removed with a brush or scaper. Retrieval and Calibration -- At the end of each measurement period (approximately 2 months), the MicroCAT was unshackled from the cable and returned to the laboratory. The stored data was uploaded to a computer using a RS-232 serial cable and Sea-Bird Electronics SEATERM software. The MicroCAT was then cleaned to remove encrusting material and calibrated with a reference instrument at 4 to 5 salinity levels, generally ranging from 30 to 5 PSU. Data Processing -- Data were processed after each retrieval using custom programs in the GCE Data Toolbox for MATLAB (parse_37sm and imp_gcesonde). Depth was calculated from recorded pressure and latitude values, and salinity and sigma-t were calculated from recorded conductivity and temperature values using standard UNESCO algorithms (reference: Unesco. 1983. Algorithms for computation of fundamental properties of seawater, 1983. Unesco Technical Papers in Marine Science No. 44, 53 pp.). Data were then plotted and visually inspected for evidence of biofouling of the conductivity sensor (i.e. prolonged periods of damped tidal oscillation in conductivity signal with no corresponding changes in temperature signal and no wind or rainfall events recorded at nearby monitoring stations, or periods of damped oscillation immediately followed by normal oscillation after instrument maintenance or replacement). Conductivity values recorded during periods of suspected biofouling were flagged as I (invalid) if visible fouling was noted in maintenance logs, and Q (questionable) if no visible fouling was noted. Daily Aggregation -- The finalized 30-minute resolution data set was filtered to remove any remaining invalid values (i.e. assigned qualifier flags of 'I' = invalid value or 'X' = excise row), then padded with empty rows to produce a monotonic time series data set with even time steps. The data records were then aggregated (grouped) by Year, Month, Day, Site, Longitude and Latitude, and relevant summary statistics were calculated for each measured variable in each group and added as data columns. Quality control rules were defined for each calculated column to flag statistics based on days with more than 35% missing values as invalid, and more than 10% missing values or 35% flagged values as questionable. Columns listing the number and percentage of missing and flagged values in the original data set for each day were also added as data columns for reference by quality control rules. Following aggregation, summary statistics flagged as invalid were removed from the daily-aggregated data set and converted to missing (NaN). b.
